NHS Mediated CdTe Quantum Dots/Albumin Conjugates and Labeling C. Elegans1

Luminescent quantum dots (QDs) are a promising alternative to organic dyes for biomedical assays and imaging. A new conjugation method, NHS mediated conjugating, for QDs and BSA was introduced. The QDs-BSA conjugates were confirmed, and their stability has been proved. Caenorhabdilis etegans (C. etegans) were used as animal models, and the imaging of QDs in the organism was studied.
