Abstract

Water soluble CdSe(S) quantum dots (QDs) were synthesized, modified and linked to antibodies, to give a CdSe(S) QD-antibody conjugated compound. The QD modification process was found to be effective by using X-ray photoelectron spectroscopy (XPS), circular dichroism and UV-visible and photoluminescence spectroscopies. The QDs were linked to the antibodies using ethyl-3-(dimethylaminopropyl)carbodimide (EDC) as the coupling agent and the stability and optical properties of both the QDs and QD-antibody conjugated compound were investigated.
