Nanocomposites of Microbial Polyglutamic Acid and Nanoclays Compatibilized by Organophosphonium Surfactants
(Wiley, 2018)
Ionic coupling of bacterial poly(γ-glutamic acid) (PGGA) with alkyltrimethylphosphonium surfactants is reported to render comb-like PGGA complexes with a biphasic-layered structure displaying periodicity at the nanoscopic ...

Biodegradable double cross-linked chitosan hydrogels for drug delivery: Impact of chemistry on rheological and pharmacological performance
(Elsevier, 2020-12)
This study investigates the impact of dual ionic and covalent cross-links (ion-XrL and cov-XrL) on the properties of chitosan-based (CTS) hydrogels as eco-friendly drug delivery systems (DDS) for the model drug diclofenac ...
