Abstract

Quantum dots are bright and stable fluorescence signal sources, but for most of applications they need an additional hydrophilization step. Unfortunately, most of existing approaches lead to QD’s fluorescence quenching, so there is a need for additional enhancing of hydrophilized QD’s brightness like UV irradiation, which can be used both on water insoluble QD’s with oleic acid ligands (in toluene) and on hydrophilized QD’s covered with UV-stable polymer (in aqueous solution). For synthesis of bright water-soluble fluorescent labels CdSe/CdS/ZnS colloidal quantum dots were covered with PAMAM dendrimer and irradiated with UV lamp in quartz cuvettes for 3 hours at the room temperature and then compared with control sample.
