We are working specifically with the reactivity of disulphide bridges in proteins - and we have verified that we can open them with UV light, provided that they are flanked with an aromatic group, eg TRP. In the open reactive state they can react with gold surfaces, or gold nano particles.
As of yet we have not tried Silver, or Aluminum, but we expect Silver to be working well.
It could be interesting to mount antimicrobial peptides onto Silver nanoparticles, and check if their antimicrobial efficiency goes up or not

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.
There is only one important assumption: you have to be interested in nano!
Nanopaprika is always looking for new partners, if you have any idea, contact me at email@example.com
