Abstract
Ag nanocluster–silica composite films have been obtained by Radio-Frequency (RF) co-sputtering on soda-lime substrates: their characteristic Localized Surface Plasmon Resonance (LSPR) can be employed for sensing applications after grafting of a specific molecule (folic acid) for the recognition of cancer cells. Preliminary results on the surface functionalization of Ag nanocluster–silica composite films by folic acid and the ability of functionalized layers to selectively recognize the proper antibody will be discussedFile in questo prodotto:
