Porous Silicon Nanostructures for Optical Sensing, Photodetection and Biomedical Applications
This community develops silicon-based nanostructures—primarily porous silicon, quantum dots, and nanowires—to create optical sensors, photodetectors, and biomedical devices.
The work centers on the fabrication of porous silicon and silicon nanocrystals using electrochemical etching and laser ablation. These structures are engineered for their optical properties, specifically photoluminescence and structural color, to serve as substrates for gas sensors, photodetectors, and biosensors. A significant portion of the research involves depositing other materials, such as metal oxides or gold nanoparticles, onto these silicon surfaces to enhance sensitivity or functionality. The applications range from detecting chemical gases and biological molecules to creating components for solar cells and medical implants.
The largest share of the community's output is found in silicon research, accounting for 2.4% of all silicon research, and 8,403 papers here. Erbium research also features prominently, with 1,154 papers representing 3.5% of that element's tracked literature.
The community comprises 11,791 papers, published most frequently in Applied Physics Letters, MRS Proceedings, and Journal of Applied Physics.
Recent work continues to focus on synthesizing nanoparticles via laser ablation for photodetectors and gas sensors, as well as modifying porous silicon for biomedical applications such as drug delivery and biosensing.
