Radiative and nonradiative rate fluctuations of single colloidal semiconductor nanocrystals
Article Abstract:
The fluctuations of the photophysical characteristics of difference types of semiconductor nanocrystals (NCs) are investigated using spectral and time-resolved single-molecule fluorescence spectroscopy. The results show that the addition of antiblinking reagents such as mercaptoethylamine accelerates the observed fluctuations between different photophysical states.

Photoinduced electron transfer between fluorescent dyes and guanosine residues in DNA-hairpins
Article Abstract:
The inter- and intramolecular quenching efficiency of DNA nucleotides with rhodamine and oxazine derivatives in aqueous solution is studied. The results show that similar to the aggregation tendency of organic dyes, oxazine and rhodamine dyes tend to aggregate with DNA nucleotides in aqueous surroundings.
