... nanoparticles are submicron-sized polymeric colloidal particles in which a therapeutic agent of interest can be embedded or encapsulated within their polymeric matrix or adsorbed or conjugated onto the surface [49]. Depending upon the method of preparation, these are of two types — nanospheres and nanocapsules. Nanocapsules are systems in which the drug is confined to a cavity surrounded by a unique polymer membrane, while nanospheres are matrix systems in which the drug is physically and uniformly dispersed [50-52]. Various types of polymer- based nanoparticles are rendered in Fig. 1. Drug nanoparticles have been shown to improve bioavailability and enhance drug solubility because of reduced particle size up to nanosize and encapsulating the drug in to water-soluble polymer. These nanoparticles serve as an excellent vehicle for delivery of a number of biomolecules, drugs, genes, and vaccines to the site of interest in vivo. The early nanoparticles were mainly formulated from polyalkyl- cyanoacrylate. They easily cross mucosal barrier due to their nanosize but they also have some disadvantage like short life span due to rapid clearance from the body by phagocytic cells. In recent years, the problem of phagocytic removal of nanoparticles has been solved by modifying the surface of nanoparticles [53]. The surface modification protected nanoparticles from being phagocytozed and removed from the blood vascular system after intravenous injections. The use of polymeric nanoparticle for drug delivery is a strategy that aims to optimize therapeutic effects while minimizing adverse effects. Nanoparticles can be prepared from a variety of materials. The selection of the base polymer is based on various designs and end application criteria. It depends on many factors such as (1) size of the desired nanoparticles, (2) properties of the drug (aqueous solubility, stability, etc.) to be encapsulated in the polymer, (3) surface characteristics and functionality, (4) degree of biodegradability and biocompatibility and toxicity, (5) drug release profile, and (6) antigenicity of the final product. Criteria for ideal polymeric carriers for nanoparticles and nanoparticle delivery systems [54] are given below in Table 6. Polymers used in controlled drug delivery, including nanoparticles, may be classified as either (1) natural and synthetic or (2) biodegradable and nonbiodegradable. Examples of naturally occurring biodegradable and biocompatible polymers used to prepare nanoparticles include: cellulose, gelatin, pullulan, chitosan, alginate, and gliadin. Example of synthetic biodegradable polymers used to prepare nanoparticles include: polylactic acid, poly-(lactide-co-glycolide) (PLGA), polyanhydrides, poly- ε -caprolactone, poly-alkyl- cyanoacrylates, and polyphosphazene. Biodegradability and biocompatibility are important properties of polymeric materials that are to be injected or implanted into the body. Non- biodegradable polymeric nanoparticles may be used for controlled drug delivery and also in the complimentary field of diagnostic imaging. Examples of nonbiodegradable, synthetic polymers include polymethacrylate, and polymethylme- thacrylate (PMMA) that has been widely used in a variety of pharmaceutical and medical applications. Specifically, PMMA Eudragit® nanoparticles can be prepared by nanoprecipitation method [55] that involves adding hydroalcoholic solution of the polymer to an organic solvent. Incorporation of poly-acrylic acid into nanoparticles increased the transfection efficiency of DNA. Polystyrene particles have been used as diagnostic agents. Among water-soluble polymers available chitosan is one of the most extensively studied. This is because chitosan possess some ideal properties of polymeric carriers for nanoparticles since it is biocompatible, biodegradable, nontoxic, and inexpensive. Furthermore, it possesses positively charge and exhibits absorption enhancing effect. These properties render chitosan a very attractive material as a drug delivery carrier. In the last two decades, chitosan nanoparticles have been extensively developed and explored for pharmaceutical application [56-58]. Chitosan is a natural polymer obtained by deacetylation of chitin, a component of crab shells. Chitosan is a poly- cationic polymer, that comprise of D -glucosamine and N acetyl- D -glucosamine linked by b-(1, 4)-glycosidic bonds. The various methods used to prepare chitosan-based nanoparticles and their applications have been extensively reviewed [59]. Chitosan can entrap drugs by numerous mechanisms including chemical cross-linking, ionic crosslinking, and ionic complexation [60]. Chitosan has been reported to be very suitable for preparation of nano- and microparticles for controlled drug release. Chitosan, particularly, chitosan nanoparticles offer many advantages due to their better stability, low toxicity, and simple and mild preparation methods, providing versatile routes of administration and has gained more attention as a drug delivery carrier and as biomedical material [61, 62]. Also, chitosan was selected for nanoparticles because of its recognized muco-adhesivity and ability to enhance the penetration of large molecules across mucosal surface [56]. They have the ability to control the release of active agents and avoid the use of hazardous organic solvents while fabricating particles since they are soluble in aqueous acidic solution. Moreover, chitosan is a linear polyamine containing a number of free amine groups that are readily available for cross-linking whereas its ...

The COVID-19 pandemic, caused by SARS-CoV-2, poses a significant global health threat. The spike glycoprotein S1 of the SARS-CoV-2 virus is known to induce the production of pro-inflammatory mediators, contributing to hyperinflammation in COVID-19 patients. Triphala, an ancient Ayurvedic remedy composed of dried fruits from three plant species—Emblica officinalis (Family Euphorbiaceae), Terminalia bellerica (Family Combretaceae), and Terminalia chebula (Family Combretaceae)—shows promise in addressing inflammation. However, the limited water solubility of its ethanolic extract impedes its bioavailability. In this study, we aimed to develop nanoparticles loaded with Triphala extract, termed “nanotriphala”, as a drug delivery system. Additionally, we investigated the in vitro anti-inflammatory properties of nanotriphala and its major compounds, namely gallic acid, chebulagic acid, and chebulinic acid, in lung epithelial cells (A549) induced by CoV2-SP. The nanotriphala formulation was prepared using the solvent displacement method. The encapsulation efficiency of Triphala in nanotriphala was determined to be 87.96 ± 2.60% based on total phenolic content. In terms of in vitro release, nanotriphala exhibited a biphasic release profile with zero-order kinetics over 0–8 h. A549 cells were treated with nanotriphala or its active compounds and then induced with 100 ng/mL of spike S1 subunit (CoV2-SP). The results demonstrate that chebulagic acid and chebulinic acid are the active compounds in nanotriphala, which significantly reduced cytokine release (IL-6, IL-1β, and IL-18) and suppressed the expression of inflammatory genes (IL-6, IL-1β, IL-18, and NLRP3) (p < 0.05). Mechanistically, nanotriphala and its active compounds notably attenuated the expression of inflammasome machinery proteins (NLRP3, ASC, and Caspase-1) (p < 0.05). In conclusion, the nanoparticle formulation of Triphala enhances its stability and exhibits anti-inflammatory properties against CoV2-SP-induction. This was achieved by suppressing inflammatory mediators and the NLRP3 inflammasome machinery. Thus, nanotriphala holds promise as a supportive preventive anti-inflammatory therapy for COVID-19-related chronic inflammation.

The lipid-based drug delivery system (LBDDS) is a well-established technique that is anticipated to bring about comprehensive transformations in the pharmaceutical field, impacting the management and administration of drugs, as well as treatment and diagnosis. Various LBDDSs verified to be an efficacious mechanism for monitoring hypertension systems are SEDDS (self-nano emulsifying drug delivery), nanoemulsion, microemulsions, vesicular systems (transferosomes and liposomes), and solid lipid nanoparticles. LBDDSs overcome the shortcomings that are associated with antihypertensive agents because around fifty percent of the antihypertensive agents experience a few drawbacks including short half-life because of hepatic first-pass metabolism, poor aqueous solubility, low permeation rate, and undesirable side effects. This review emphasizes antihypertensive agents that were encapsulated into the lipid carrier to improve their poor oral bioavailability. Incorporating cutting-edge technologies such as nanotechnology and targeted drug delivery, LBDDS holds promise in addressing the multifactorial nature of hypertension. By fine-tuning drug release profiles and enhancing drug uptake at specific sites, LBDDS can potentially target renin-angiotensin-aldosterone system components, sympathetic nervous system pathways, and endothelial dysfunction, all of which play crucial roles in hypertension pathophysiology. The future of hypertension management using LBDDS is promising, with ongoing reviews focusing on precision medicine approaches, improved biocompatibility, and reduced toxicity. As we delve deeper into understanding the intricate mechanisms underlying hypertension, LBDDS offers a pathway to develop next-generation antihypertensive therapies that are safer, more effective, and tailored to individual patient needs.

Plants experience diverse abiotic stresses, encompassing low or high temperature, drought, water logging and salinity. The challenge of maintaining worldwide crop cultivation and food sustenance becomes particularly serious due to drought and salinity stress. Sustainable agriculture has significant promise with the use of nano-biotechnology. Nanoparticles (NPs) have evolved into remarkable assets to improve agricultural productivity under the robust climate alteration and increasing drought and salinity stress severity. Drought and salinity stress adversely impact plant development, and physiological and metabolic pathways, leading to disturbances in cell membranes, antioxidant activities, photosynthetic system, and nutrient uptake. NPs protect the membrane and photosynthetic apparatus, enhance photosynthetic efficiency, optimize hormone and phenolic levels, boost nutrient intake and antioxidant activities, and regulate gene expression, thereby strengthening plant’s resilience to drought and salinity stress. In this paper, we explored the classification of NPs and their biological effects, nanoparticle absorption, plant toxicity, the relationship between NPs and genetic engineering, their molecular pathways, impact of NPs in salinity and drought stress tolerance because the effects of NPs vary with size, shape, structure, and concentration. We emphasized several areas of research that need to be addressed in future investigations. This comprehensive review will be a valuable resource for upcoming researchers who wish to embrace nanotechnology as an environmentally friendly approach for enhancing drought and salinity tolerance.

Methods: PLGA nanoparticles loaded with Glycyrrhizin were synthesized by an adapted emulsion-evaporation method. Nanoparticles were evaluated for particle size, entrapment efficiency and Polydispersiblity index (PDI). Further, Box Benkhen design was applied for optimization of the formulation parameters and the effect of three independent variables such as PLGA concentration, amount of glycyrrhizin, polyvinyl alcohol (PVA) concentration on particle size, polydispersiblity index and the entrapment efficiency (response variables) were investigated. The antioxidant capacity of optimized nanoparticle formulation loaded with glycyrrhizin was compared with free glycyrrhizin by DPPH assay. Results: The particle size, entrapment efficiency and PDI of optimized Glyc-NPs was found to be 144.20 nm, 68.0% and 0.315 respectively. Optimized Glyc-NPs showed sustained release of drug 79.06% in 48 hours with improved free radical scavenging activity than isolated Glycyrrhizin. Conclusion: PLGA nanoparticles were found to be suitable carrier for Glycyrrhizin at lower levels than originally required for enhanced functional properties.
... Chitosan films contain inherent antibacterial action and prevent the development of a wide range of bacteria and fungi, including Salmonella Typhimurium and Staphylococcus aureus. One of the reasons for chitosan's antibacterial properties is its positively charged amino group, which interacts with the negatively charged microbial cell membrane, causing the outflow of proteinaceous and other intracellular components of the microorganisms [23].

This study describes the preparation, physicochemical characterization, controlled release, and bioavailability of chitosan nanoparticles (CTSNPs) loaded with salvianolic acid B (SlB) and tanshinone IIA (TnA). It also aimed to assess their antibacterial activity against foodborne pathogen. SlB and TnA were loaded on CTSNPs with ionic gelation method. They were then in vitro characterized via infrared and electron microscopy. SlB/TnA/CTSNPs showed excellent colloidal properties (size 129.3 nm and zeta-potential + 31.8 mV); the encapsulation efficiency (EE) of SlB/CTSNPs and TnA/CTSNPs was 51.43 and 88.36%, respectively. The loading capacity (LC) of SlB/CTSNPs and TnA/CTSNPs was 7.85 and 12.61%, respectively. SlB and Tan II were released in vitro from SlB/TnA/CTSNPs for over 45 h, demonstrating that these NPs are effective at regulating the release of SlB and TnA. SlB/TnA/CTSNPs outperformed chitosan, SlB, and TnA alone in terms of bactericidal efficacy against foodborne pathogens (Staphylococcus aureus and Salmonella Typhimurium). S. aureus was more susceptible than S. Typhimurium. After only 10 h of exposure, the scanning microscopic pictures of bacteria treated with SlB/TnA/CTSNPs revealed that cells had completely exploded or lysed. In terms of health and food safety, these eco-friendly nanosystems could be a desirable substitute for synthetic preservatives.

Introduction Olanzapine (OLZ) is a psychotropic class drug commonly used to treat schizophrenia, bipolar disorder, and acute manic episodes. It has less water solubility, resulting in a slow dissolution rate and oral bioavailability. Therefore, the development in oral dosage forms is required to enhance the drug solubility. Method The solid dispersion of olanzapine is prepared by spray drying technique. The solution of polyvinylpyrrolidone K-30 (PVP K-30), mono amino glycyrrhizinate pentahydrate (GLY), OLZ and silicon dioxide were dissolved in distilled water and ethanol and spray dried to get the solid dispersion. Solid dispersion was characterized for surface morphology, solubility, encapsulation efficiency (EE), X-ray diffraction (X-RD), Differential Scanning Calorimeter (DSC) and drug-polymer interaction by Fourier transforms infrared spectroscopy. Results The amorphous nature of the drug's incorporation in solid dispersion was confirmed by X-RD analysis. Prepared solid dispersion showed higher solubility, 11.51 mg, than pure OLZ (0.983 mg ml⁻¹), while the range of EE was found to be between 64 to 90 %. Conclusions The solubility and dissolution rate of the OLZ can effectively increase by spray-dried solid dispersion. Plackett–Burman screening design plays a vital role in understanding the effect of independent variables on EE and solubility.
