ABSTRACT
The importance of silicon photonic devices extends beyond passive
structures for light guiding and light emission. Nanostructured
silicon devices have emerged as gas, chemical, and biological
sensors, aswell as drug delivery agents,molecular separationmedia,
and interfaces for tissue engineering. While early silicon-based
sensing devices were based on bulk silicon properties, more recent
devices take advantage of the unique properties of nanostructured
silicon-based devices. This chapter highlights several advances in
the area of biological applications of silicon nanostructures.
