Abstract
A convenient room-temperature bioinspired technique has been developed to synthesizehybrid nanocomposites consisting of well-dispersed CdS quantum dots (QD) and thesubstrate silk fibroin fibers (SFF). The biomaterial SFF provides both a supportingsubstrate and functional sites for the in situ generation of QD-CdS, which is supported byFTIR and PL measurements. The solid QD-CdS/SFF nanocomposites could be usefulin photocatalyst, novel luminescence and photoelectron transfer devices. TheQD-CdS/silk fibroin (SF) colloid, in which SF acts as both an inherent biocompatibilizerand an efficient passivator of trap sites on the QD-CdS surface, is also availablefor some potential applications in the biological fields. The bioinspired methodand relevant ideas could extend to fabricating other functional hybrid materials.
