WebIn the current work, a facile strategy for the light-stimuli actuator was proposed based on a homogeneous chitosan (CS)/graphene oxide (GO) nanocomposite hydrogel. Controllable actuation of the CS/GO hydrogel film has been realized as a result of the water gratitude induced by the near-IR (NIR)-light illumination. WebGraphene oxide (GO) was cross-linked with chitosan to yield a composite (GO-LCTS) with variable morphology, enhanced surface area, and notably high methylene blue (MB) …

WebJan 3, 2024 · We investigated a novel drug delivery system comprising nanoparticles based on chitosan/graphene oxide (GO)/folic acid for targeted delivery of chemotherapeutic drugs. In this research, GO is accompanied with chitosan as natural cationic polysaccharide to increase compatibility. First, GO was synthesized, then chitosan was grafted to it by … WebJul 15, 2024 · Chitosan is a multifunctional polymer with abundant reactive amino groups and hydroxyl groups on its backbone, which significantly contributes to the preferential sorption and diffusion of water in CS membranes and also make it easy to be modified [31]. WebJul 1, 2024 · Chitosan quaternary ammonium salt, namely hydroxypropyltrimethyl ammonium chloride chitosan (HACC), is a quaternized chitosan derivative, which is usually synthesized by introducing a permanently positively charged group through an etherification reaction (Du et al., 2024; Verheul et al., 2008; Zhao et al., 2015; Zhao et al., 2024 ). phone number to scream into
