  • Patent number: 11911999
    Abstract: Fluorescence-based techniques are the cornerstone of modern biomedical optics with applications ranging from bioimaging at various scales (organelle to organism) to detection and quantification of a wide variety of biological species of interest. However, feeble fluorescence signal remains a persistent challenge in meeting the ever-increasing demand to image, detect and quantify biological species of low abundance. Disclosed herein are simple and universal methods based on a flexible and conformal elastomeric film adsorbed with plasmonic nanostructures, referred to as “plasmonic skin” or “plasmonic patch”, that provide large and uniform enhancement of fluorescence on a variety of surfaces, through an “add-on-top” process.
    Type: Grant
    Filed: May 6, 2022
    Date of Patent: February 27, 2024
    Assignee: Washington University
    Inventors: Srikanth Singamaneni, Jingyi Luan, Jeremiah Morrissey, Evan Kharasch
  • Patent number: 11813056
    Abstract: The present disclosure is directed to microneedle patches for direct sampling and ultrasensitive detection of protein biomarkers in dermal interstitial fluids. The microneedle patches are comprised of polymers with high protein absorption capability (e.g. polystyrene) and are modified with capture biorecognition elements that are specific to target analytes in the interstitial fluid (ISF). Systems and methods are further provided for detection of a target ISF analyte obtained by in vivo sampling of the ISF using a microneedle patch.
