Although it is known that fluorescent techniques making use of standard organic dyes are widely used for this purpose, the development of a new method was proposed using nanotechnology; in particular the use of nano optical reporters also called quantum dots (QDs). In order to achieve this goal, the research work was divided into four main tasks: (1) synthesis and characterization of CdSe/ZnS core-shell QDs; (2) design of dihydrolipoic acid (DHLA) ligands appended to oligo and poly (ethylene) glycols (PEG) with different functional groups to generate biocompatible QDs; (3) bioconjugation of QDs to monoclonal antibodies based on sophisticated protocols and (4) some chemical and biological applications of the synthesized non-conjugated and conjugated nanoparticles.(...)
