Even if the first published article on a porous silicon (PSi)-based biosensor dates back to more than twenty years ago, this technology still attracts great attention from many research groups around the world. In this brief review, the pros and cons of porous silicon-based optical biosensors will be highlighted on the basis of some recent results and published papers on this subject. The aim of the paper is to give a straightforward introduction to PhD students and young researchers on this subject, which is particularly full of educative content, since it is highly multidisciplinary. Fabrication of PSi-based optical biosensors requires competencies related to many different scientific topics ranging from material science, physics and optics to healthcare and environmental monitoring through surface chemistry and more.

Abstract PSi structures have unique physical and optical properties, which are being exploited for a numerous biomedical applications including biosensing, bioimaging, tissue engineering, and drug delivery. Different PSi optical structures can be fabricated to improve the sensitivity of the optical measurements. A very high surface area per volume of PSi can be used for the higher loading of target analytes in a small sensor area, which helps in increasing sensitivity and allows the miniaturization of biosensor. The specificity of PSi biosensor to the target analyte can be inferred by immobilizing the corresponding bioreceptor such as DNA, enzyme, or antibody via different conjugation chemistries. Finally, PSi is biocompatible material that offers additional advantage in comparison to other sensing platforms for in vivo implantable biosensing applications. This paper reviews fabrication, surface modification, biofunctionalization, and optical biosensing applications of PSi structures with special emphasis on in vivo and PSi photonic particles biosensing.

AbstractThe electrical reliability properties of PZT (54/46) thin films have been measured for the purpose of integrating this material with silicon-based microelectromechanical systems. Ferroelectric thin films of PZT were prepared by metal organic decomposition. The charge trapping and degradation properties of these thin films were studied through device characteristics such as hysteresis loop, leakage current, fatigue, dielectric constant, capacitancevoltage, and loss factor measurements. Several unique experimental results have been found. Different degradation processes were verified through fatigue (bipolar stress), low and high charge injection (unipolar stress), and high field stressing (unipolar stress).

AbstractSilicon-based polymers with σconjugated electrons have specific properties; photoreactivity for microlithography and photoconductivity for hole transport materials. To explore the possibility of combining these two properties to develop photoresists with electronic transport capability, photoconductivity of polysilanes is investigated in connection with their photoinduced chemical modification. Increase in photocurrent is observed accompanying photoreaction of poly(dimethylsilane) vacuum deposited films. This increase is found to be greatly enhanced in oxygen atmosphere. Such changes of photocurrent can be explained by charge transfer to electron acceptors from Si dangling bonds postulated to be formed during photoreaction.
