Congrats Soren! Best Talk of the Day at Porus Semiconductor – Science and Technology Conference
May. 4, 2026—Biofunctionalized Zwitterionic Polymers for High Specificity Porous Silicon Biosensing Porous silicon (PSi)-based optical biosensors are a promising platform for rapid, quantitative diagnostics, offering label-free molecular detection with high intrinsic sensitivity and compatibility with paper-based lateral flow assays and smartphone readout. However, their operation in complex biological media remains limited due to biofouling and hydrolytic instability....
Congrats Ginny! Parkhutik Prize, Most Outstanding Poster at Porus Semiconductor – Science and Technology (PSST) conference
May. 4, 2026—Control of Fluid Flow in Paper-based Porous Silicon Biosensor for Enhanced Sensor Performance Porous silicon (PSi)-on-paper sensors are a promising platform for sensitive and quantitative rapid diagnostic tests. Here, we report a combined vertical and lateral flow geometry in which lateral-flow microchannels control the incubation time of target molecules in the PSi membrane active...
Congrats Chris! Best Poster Presentation Award in the SPIE Active Photonic Platforms conference at SPIE Optics and Photonics
Aug. 22, 2025—Heterogenous integration of VO₂ nanopatches on subwavelength-engineered antislot photonic crystal for optical switching We report the heterogeneous integration of the optical phase change material, vanadium dioxide (VO₂), on a subwavelength-engineered silicon antislot photonic crystal cavity as the foundation for a high extinction ratio, ultrafast optical switch. Two 50 × 250 nm patches of VO₂ are...
Congrats Sebastian! Best layout Award for his poster at VINSE 14th Annual Undergraduate Research Symposium
Aug. 1, 2025—Paper Based Microfluidic Channels for Porous Silicon Biosensors Developing low cost, highly sensitive, and accessible biosensing platforms is critical for widespread diagnostic applications. Porous silicon (PSi) is a promising material for these platforms due to its high surface area for detecting molecules, chemical and biological compatibility, and ease of fabrication. Integrating PSi membranes with paper...
