27 March 2006 The synthesis of silicon and germanium quantum dots for biomedical applications
Author Affiliations +
Silicon quantum dots have been synthesized in micelles. Particle sizes have been ascertained by transmission electron microscopy and UV-Vis absorption and photoluminescence spectroscopy. The surface of the silicon and germanium particles produced have been modified to produce hydrophobic and hydrophilic particles by reaction with either with 1-heptene or allylamine respectively. For biological applications control of the surface character of the nanocrystals is essential. FTIR spectra show the surface modification of the particles by 1-heptene or allylamine.
