This chapter presents a literature survey of the applications of porous silicon in BioMEMS (biological/biomedical microelectromechanical systems). This material possesses properties particularly suitable for biomedical purposes biocompatibility, biodegradability, photoluminescence, ability to precisely control the pore size and shape, and possibility to easily modify the surface chemistry. Many applications can, for instance, be found in the fields of sensing and delivery of therapeutics. It is expected that the number of BioMEMS using porous silicon will continue to increase in the future with the development of lab-on-a-chip/microfluidic devices. 

As can be seen in both tables, pSi presents numerous applications in the BioMEMS held due to properties particularly suitable for biomedical purposes (Salonen and Lehto 2008) biocompatibibty, biodegradability, photoluminescence (Canham 1990), ability to precisely control the pore size and... 

To meet this unmet need in regenerative tissue engineering, a breakthrough was recently made in developing soft and elastic biodegradable photoluminescent polymers (BPLPs) with mnable and in vivo detectable fluorescence with emission from...

Above all metalloid materials that have heen isolated as nanostructures, silieon nanoparticles (SiNPs) have rapidly drawn the attention of the seientific community primarily due to the demonstration of its efficient visible photoluminescence and high hiocompatihility. Contraiy to the perceived poor hiocompatihility of silicon, SiNPs are either bio-inert, bioactive or biodegradable depending on its porosity and pore size. Hence, they have been explored as biocompatible luminescent drug delivery systems for in vitro and in vivo applications. ...
