Abstract Biocompatible polymer chitosan has note-worthy applications in biomedical science. Nanohybrids
synthesized by using chitosan as an encapsulating unit for polyoxometalates (POMs) and
study of its biomedical applications is a fast-emerging field. In this research work, a lacunary
polyoxometalate (α-K8SiW11O39) has been synthesized and then alkylsilane has been inserted
into its lacunary position. It has been then reacted with 2-hydroxy-1-naphtaldehyde followed by
copper metalation and finally encapsulated into chitosan by using the ionotropic gelation
technique, in which the chitosan and the POM served as cation and anion, respectively. The
bands in UV-Vis spectra at characteristic wavelength indicate… More >
