Coupling of chitin whisker (CTWK) or water-soluble chitosan (WSCS) with magnetic nanoparticles (MAG) via a covalent linkage by using a silane coupling agent in an aqueous system is proposed. The use of the silane coupling agent glycidoxypropyltrimethoxy, having a trimethoxy silane as well as an epoxide functionality, allows one step coupling between CTWK or WSCS and MAG. The MAG derivatives obtained...
Chitosan nanospheres (CSNS) with a core-corona structure containing hydrophobic phthaloyl group and a hydrophilic poly(ethylene glycol) group perform as the backbone to allow interaction with magnetic nanoparticles (MAG). Having hydrophilic corona favors the coverage of MAG on the CSNS surface to form CSNS–MAG. In contrast, having hydrophobic core allows the incorporation with MAG if the MAG is in...
