Fishing for G-quadruplexes in solution with a perylene diimide derivative labeled with biotins
2018
A new fluorescent, non‐cytotoxic perylene diimide derivative with two biotins at the peri position, PDI2B, has been synthesized. This molecule is able to interact selectively with G‐quadruplexes with scarce or no affinity towards single‐ or double‐stranded DNA. These features have made it possible to design a simple, effective, safe, cheap, and selective method for fishing G‐quadruplex structures in solution by use of PDI2B and streptavidin coated magnetic beads. The new cyclic method reported leads to the recovery of more than 80 % of G‐quadruplex structures from solution, even in the presence of an excess of single‐stranded or duplex DNA as competitors. Moreover, PDI2B is a G4 ligand that…
Fabbricazione di LED bianchi tramite down-conversion di coloranti basati su perilene
2012
A high efficiency cool white LED was obtained by generation of yellow down-conversion from a GaN/InGaN blue LED. Using photoluminescence of a perylene-based polymer dye we achieved a good substitute for conventional inorganic color conversion.
