We report for the first time the use of quaternized chitosan (QCHI) for the immobilization of gold nanopartides (NP) and glucose oxidase (GOD), the characterization of the resulting platform and its biocatalytic activity ...

The electrochemical behavior of the cationic polymer chitosan-gtmac (Ch-GTMAC), at the polarized water / 1,2-dichloroethane interface was studied. This polymer was obtained by nucleophilic reaction of chitosan (Ch) with ...

The antimicrobial activity of chitosan and derivatives to human and plant pathogens represents a high-valued prospective market. Presently, two low molecular weight derivatives, endowed with hydrophobic and cationic character ...

We report for the first time the use of quaternized chitosan (QCHI) for the immobilization of gold nanoparticles (NP) and glucose oxidase (GOD), the characterization of the resulting platform and its biocatalytic activity ...

Self-assembled multilayers of quaternized chitosan (QCHI) and gold nanoparticles (AuNPs) were built up on quartz and gold substrates. To evaluate the effect of the surface coverage of AuNPs on the structural, optical and ...

With increasing emphasis on environmental care 7 and use of renewable resources, simple and effective dendroniza- 8 tion processes were performed to obtain chitosan derivatives. We 9 present different alternatives for ...
