Luminous Chitosan-Dye Nanocomposite Particles with Enhanced Lifetime and Stability

Abstract:

Nanoparticular chitosan-dye nanocomposites were prepared by a facile ionotropic gelation, which show a much improved stability against UV and ozone attack. The nanocomposites do not contain any toxic material. Also, as natural occurring biopolymeric chitosan is used as the matrix material, the nanocomposite is biocompatible and biodegradable with high bioaffinity. After suitable bioconjugation, the developed luminous chitosan-dye nanocomposites can be used as target biolabels in various medical and biomedical applications.
