Study of the Fluorescence Based Applications of Pyrene-Tagged Poly(N-vinyl-2-pyrrolidone)
2016
In this study we have explored the fluorescence based applications of luminescent pyrene-tagged PNVP (PyPNVP) reported in our previous work (Int. J. Polym. Mater. Polym. Biomater. 2016, 65, 269−276). PyPNVP has successfully acted as “turn off” chemosensor for metal ions Cu2+, Hg2+, and Pb2+. It has also successfully acted as a fluorescent probe for critical micellar concentration (CMC) determination of amphiphilic block copolymer of poly(d,l-lactide) and poly(N-vinylpyrrolidone) (PDLLA42-b-PNVP120) (Mn = 19 400 g/mol and PD = 1.52). It has also successfully shown an interaction with both plasmid and calf thymus (CT) deoxyribonucleic acids (DNAs) as evidenced by its fluorescence quenching. A different magnitude and type of quenching has been observed for both the cases which may be useful in distinguishing different kinds of DNAs. In order to further understand the potential of PyPNVP in various biotechnological processes, its binding property with bovine serum albumin (BSA) has also been studied. The effi...
