Due to its properties porous silicon is a material with high potential to be applied in bio-delivery carriers and biosensors. To enhancement the capacity of porous silicon as biosensor, gold nanoparticles are introduced in its structure. One of the most used methods to obtain porous silicon/Au nanoparticles is metal salt-assisted chemical etching. The high surface of porous silicon matrix and the Au nanoparticles allow the increment of the sensitivity of the biosensor. This structure can be use
