The paper "The Photophysics of Porous Silicon: Technological and Biomedical Implications" from LNBE has been published in the Yadernaya Fizika i Inzhiniring.

A review article from the Nano-Heterostructures Group of LNBE has been published in the 2013 second issue of the Russian journal Yadernaya Fizika i Inzhiniring [Nuclear Physics and Engineering]. The article outlines the current views on the mechanisms of a wide range of photophysical phenomena characteristic of porous silicon and their potential practical applications.

Studies carried out during the past two decades have shown that porous silicon has a unique combination of structural, optical, and photophysical properties. Photonic crystals, sensors of organic and inorganic compounds, photovoltaic devices, etc. based on this material are being developed and manufactured.

Studies on the energy and charge transfer from optically excited porous silicon to molecules and other objects adsorbed on its surface constitute a special field of research. These studies have extremely numerous, sometimes unexpected, practical implications. Energy and charge transfer underlies the operation of photochemical sensors, efficient ion sources for mass spectrometry, antitumor drugs, and targeted drug delivery systems. Porous silicon is biocompatible; hence, it is advantageous over most other organic and inorganic materials used in biology and medicine.

The paper gives a comprehensive summary of recent advances in the photophysics of porous silicon, a systematic overview of characteristic photoprocesses, and most graphic examples of their practical applications.
