Investigation of PL spectra of porous silicon with inclusions of organic molecules

Abstract

Development of biosensors based on nanostructured solid matrix is actual and promising task. One of the most suitable materials for this purpose is silicon. First, the technology for producing of porous silicon is well developed, that allows to obtain the thin nanostructural layers with reproducible parameters, namely, thickness, pore size, surface morphology, etc. Second, the surface of porous silicon absorbs and good keeps the biological complexes which can be sensitive to various kinds of toxic molecules.
