Porous silicon a nanostructure for applications in nanoenergetic devices and biosensors

Porous silicon (SP) has established itself as a key material in the development of nanoenergetics and biosensors, standing out for its unique properties and ability to integrate into MEMS (Microelectromechanical Systems) systems. This work addresses the fabrication of SP nanostructures and SP microcavities using electrochemical anodizing and analyzes the impregnation of SP with solid oxidants for applications in micropropulsion and impulse generation. The reflectance spectrum is obtained so that the optical properties of SP and SP microcavities are studied so that optoelectronic devices have good performance. The results demonstrate the ability of SP to generate high combustion rates and its usefulness as an energy material in integrated systems, as well as its stability and efficiency that can be improved in future studies through passivation techniques. In addition, macropore formation SP and SP microcavities can be used as biosensors for immobilization of receptors with different sizes and varied applications. This article underlines the versatility and potential impact of SP on advanced technologies, opening up new avenues for its application in science and engineering.
