Theporous silicon smart particles (PSSP) was directly prepared by a chemistry etching reaction with silicon wafer. The DBR layer is chemically further functionalized with biotin before the etching of the host layer. Resulting porous silicon (PS) was removed from the Si substrate by an applying of electropolishing current. Prepared Ge-NPs were infused into the host layer of PS free-standing film. Samples were then made into particles by ultrasonic fracture in an organic solution. PSSP is used as biosensor for the detection of avidin. PSSP is characterized by FE-SEM, FT-IR, EDX, Fluorescence spectroscopy. |
