A comb-type multifunctional macromonomer G10 has been synthesized and characterized to replace triethylene glycol dimethylacrylate (TEGDMA) as a new type macromonomer in 2,2-bis(4-(2-hydroxy- 3-methacryloxypropoxy) phenyl)-propane (Bis-GMA) dental resin system. Photopolymerization kinetics of the dental resin system were monitored by real-time IR (...

A fluorinated acrylate monomer (4-TF-PQEA) without BPA (bisphenol-A) structure was synthesized and mixed with triethylene glycol dimethacrylate (TEGDMA) to used as dental resin system in order to achieve lower water sorption and reduce human exposure to BPA derivatives. Double bond conversion (DC) was measured using Fourier transform infrared spect...

... The characteristic absor bands of pure CTS are presented in Table 1. Several have authors reported FTIR sp of collagen type I and GMA [30][31][32][33][34]. The relative intensity of the primary amide group related to stretching vibration of C=O bonds at 1650 cm −1 decreased, especially for (CTS-g-GMA)-Col and ((CTS-g-GMA-AuNPs)-Col nanocomposites. ...

Herein, we report the synthesis of Au nanoparticles (AuNPs) in chitosan (CTS) solution by chemically reducing HAuCl4. CTS was further functionalized with glycidyl methacrylate (chitosan-g-glycidyl methacrylate/AuNP, CTS-g-GMA/AuNP) to improve the mechanical properties for cellular regeneration requirements CTS-g-GMA/AuNP. Our nanocomposites promote excellent cellular viability and a positive effect on cytokine regulation in the inflammatory and anti-inflammatory response of the skin cells. After 40 days of nanocomposite exposure to a skin wound, we proved that our films had better skin wound healing capacity in comparison with a commercial one (TheraForm®) and the presence of the collagen allows better cosmetic aspect in the skin regeneration in comparison with the nanocomposite with an absence of this protein. Electrical percolation phenomena in such nanocomposites were used as a guiding tool for best nano-composite performance. Our results suggest that chitosan-based Au nanocomposites show great potential for skin wound repair.
