Abstract

Cadmium sulfide and lead sulfide semiconducting nanoparticle chains have been fabricated for the first time by exploiting a general property of proteins, amyloidogenicity. The diameter of the CdS and PbS nanowires was tuned in the range of ∼50 to ∼350 nm by changing the process parameters. The nanoparticle chains were characterized by field emission scanning electron microscopy, UV-visible spectroscopy, transmission electron microscopy, electron energy loss spectroscopy and high-resolution transmission electron microscopy.
