Abstract:A series of reactive oxygen species-responsive degradable poly(amino acid)s (PAAs) was synthesized via in situ melting polycondensation. The PAAs were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and mechanical property analysis. The degradation and biocompatibility of the PAAs were also studied to evaluate their applicability as biomedical materials. The results show that the PAAs posse… Show more
“…Then, it was proven that the methionine content accelerated the poly(amino acid) degradation in oxygen-rich environments. 61 Apart from the NPs, polypeptides can self-assemble forming fibers that work as precursors of hydrogel formation. That is the case of a PEG-containing peptide that conjugates the coupling of an a-acyl-brominated tetra-phenylalanine peptide (FFFF) with a disulfide-bridged polymeric PEG scaffold, MeO-FFFF-PEG-FFFF-OMe.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
