Abstract

We report here on the use of peptide-amphiphile (PA) nanofibers displaying the S(P)RGD peptide sequence on their exterior as templates for the mineralization of cadmium sulfide (CdS). At low Cd:PA ratios, the nanofibers nucleate and organize quantum-confined 3-5 nm CdS nanocrystals into linear arrays. Tubular structures, in which the PA fibers are completely encapsulated by the semiconductor, are produced at higher Cd:PA ratios.
