Hot Article: Photocrosslinking the polystyrene core of block-copolymer nanoparticles

Researchers from Princeton University and University of Connecticut have shown that 4,4′-diazidobiphenyl is an efficient photoactivatable crosslinker for polystyrene.

Crosslinking of the core of polystyrene-block-poly(ethylene oxide) copolymer nanoparticles was achieved by encapsulation of small molecule aryl diazides (4,4′-diazidobiphenyl) and subsequent photolysis. Nanoparticles modified in this way showed high thermal stability and have potential to be used as nanobeads for PCR. It was also found that 4,4′-diazidobiphenyl can confer solvent resistance to thin films of polystyrene.
