Gold Nanorods Crosslinking Pnipam Hydrogels Via Dynamic
Jan 22, 2021 Gold nanorod AuNR nanocomposite hydrogels have attracted increasing attention due to the photothermal effect of AuNRs. However, a facile strategy that avoids multi-step surface modification for synthesis of AuNR crosslinkers is still a critical challenge. Here, AuNRs crosslinking PNIPAM hydrogels were prepared by polymerization of NIPAM with N,N-bisacryloylcystamine
Goldchitosan Nanocomposites With Specific Near
Goldchitosan nanocomposites were synthesized and evaluated as a therapeutic agent for the photothermal therapy. Gold nanoparticles Au NPs with controllable optical absorption in the near infrared NIR region were prepared by the reaction of chloroauric acid and sodium thiosulfate. To apply these particles to cancer therapy, the bare Au NPs were coated with chitosan CS, O-carboxymethyl ...
