摘要
Biological passivation of porous silicon (PSi)-based optical devices is demonstrated. Infiltration by small amphiphilic fungal proteins called HFBs changes the wettability of the PSi surface (see figure) and protects the sponge-like structure against dissolution by basic solutions. This protein membrane leaves the sensing ability of an optical transducer unchanged, adding chemical stability that can be the key in biomolecular experiments.
