Abstract
Quantum dots (QDOTs) have been widely recognized by the scientific community and the biotechnology industry, as witnessed by the exponential growth of this field in the past several years. We describe the synthesis and characterization of visible and near infrared QDots - a critical step for engineering organic molecules like proteins and peptides for building nanocomposite materials with multifunctional properties suitable for biological applications.

Normalized photoluminescence emission spectra of core CdTe QDOTs covered with varying CdSe shell. A clear shift from the visible towards the near infrared spectra can be observed by sequential deposition of Cd and Se shell precursors.
