ABSTRACT

This chapter outlines the synthesis, fabrication, modification, and properties of silicon nanowires (SiNWs) and their applications in biomedicine such as biosensors, biomaterials, tissue engineering, and drug delivery. It believes not only for the life science community but also for engineers and physicists to broaden their research areas. SiNWs have already proved their invaluableness in the field of biomedicine. Their physical and chemical versatility will only increase the number of areas where they are useful in the future. Field effect transistors (FET) biosensor applications already provide unmatched sensitivity which we predict to increase as SiNW fabrication and synthesis methods are coupled with new advanced nanofabrication methods. Monodispersed colloids result in a narrow diameter distribution and nanowire density is controllable by colloid concentration. Moreover, these colloids can be deposited on substrate surfaces in patterns by using soft lithography methods to obtain patterned SiNW arrays.
