A biodegradable engineered nanoplatform combining anti-angiogenic activity and targeting of cancer cells to improve the anticancer activity of docetaxel (DTX) is here proposed. Indeed, we have developed biodegradable nanoparticles (NPs) of poly(ethylene glycol)-poly(ε-caprolactone), exposing on the surface both folate motifs (Fol) for recognition i...

Herein, we have developed sprayable dispersions of mucoadhesive nanoparticles (NPs) made of zein, a hydrophobic plant-based protein, for the buccal delivery of curcumin (CUR), a poorly water-soluble polyphenol. NPs were prepared by the liquid-liquid dispersion method using an antisolvent water solution without or with beta-cyclodextrin (CD). NPs we...

The presence of rare but highly tumorigenic cancer stem cells (CSCs) within the tumors is recognized as one of the major reasons of failure of conventional chemotherapies, mainly attributed to the development of drug resistance and increasing metastatic potential. Here, we propose a therapeutic strategy based on the simultaneous delivery of docetax...

Given the limited number of materials available to design delivery platforms for nutrients, the rational combination of raw materials already approved as food ingredients and their processing through nano-micro technology can offer a unique tool for innovation. Here, we propose a nano-in-micro strategy to produce powders based on the hydrophobic pr...

Nanoparticles (NPs) based on amphiphilic block copolymers of polyethylene glycol (PEG) and biodegradable polyesters are of particular current interest in drug nanodelivery due to their easily manipulated properties. The interaction of these NPs with biological environments is highly influenced by shell features, which drive biological identity afte...

Inhibition of tumor angiogenesis is considered as a valuable clinical strategy to treat some tumors, although benefits in term of progression-free and overall survival have been modest. Recent findings have pushed toward the use of antiangiogenic drugs in combination with chemotherapy regimens to potentiate therapeutic outcome. Herein, we propose a...

Correction for ‘Biodegradable nanoparticles bearing amine groups as a strategy to alter surface features, biological identity and accumulation in a lung metastasis model’ by Diletta Esposito et al., J. Mater. Chem. B , 2018, 6 , 5922–5930.

Cancer therapies based on the combinations of different drugs and/or treatment modalities are emerging as important strategies for increasing efficacy and cure, decreasing unwanted toxicity and overcoming drug resistance, provided that optimized drug concentration ratios are delivered into the target tissue. To these purposes, delivery systems such...

Polymer-based nanoparticles (NPs) with a cationic charge have been emerged recently as a potent nanotool due to their unique ability to penetrate deeply inside tumor tissue and to interact preferentially with plasma membrane of cancer cells. In this paper, we propose a general strategy to obtain biodegradable cationic NPs of poly(epsilon-caprolacto...

Polymeric nanoparticles (NPs) of poly(ε-caprolactone) (PCL) covered with a hydrophilic poly(ethylene glycol) (PEG) shell are usually prepared from diblock PEG-PCL copolymers through different techniques. Beside PEG, NPs can be decorated with targeting ligands to accumulate in specific cell lines. However, the density and conformation of PEG on the...
