  • Photonic Crystal Nanobeam Biosensors Based on Porous Silicon 
    Rodriguez, Gilberto A.; Markov, Petr; Cartwright, Alyssa P.; Choudhury, Moinul H.; Afzal, Francis O.; Cao, Tengfei; Halimi, Sami I.; Retterer, Scott T.; Kravchenko, Ivan I.; Weiss, Sharon M. (Optics Express, 2019)
    Photonic crystal (PhC) nanobeams (NB) patterned on porous silicon (PSi) waveguide substrates are demonstrated for the specific, label-free detection of oligonucleotides. These photonic structures combine the large active ...
  • Porous Silicon Sensors 
    Cao, Tengfei; Carfano, Caitlin; Rodriguez, Gilberto A.; Choudhury, Moinul H.; Afzal, Francis O.; Weiss, Sharon M. (Progress in Biomedical Optics and Imaging - Proceedings of SPIE, SPIE Digital Library, 2019-03-05)
    Porous silicon (PSi) has been recognized as an advantageous material for use in optical biosensors due to its large internal surface area, ability to form multilayer optical structures, and compatibility with standard ...
  • Thermally Carbonized Porous Silicon for Robust Label-Free DNA Optical Sensing 
    Layouni, Rabeb; Choudhury, Moinul H.; Laibinis, Paul E.; Weiss, Sharon M. (Scopus, 2020)
    In this work, thermal carbonization is shown to provide the necessary surface passivation to enable highly robust DNA detection on a porous silicon (PSi) platform, overcoming previous corrosion challenges with detection ...
