The rapidly developing field of porous silicon-based biosensors that utilize optical transduction is comprehensively reviewed by distinguishing the differing strategies for small- and moderate-size biomolecular analytes and the challenges with analysis of complex biofluids. A number of topics are identified for future research that should lead to one-shot disposable chip-based systems becoming commercially avialable.
