Latest Patents

Qi-Huo Wei holds a patent for a "Real-time, single-step bioassay using nanoplasmonic resonator with ultra-high sensitivity." This invention features a nanoplasmonic resonator (NPR) that comprises a metallic nanodisk with alternating shielding layers. The NPR is designed to have a tagged biomolecule conjugated or tethered to its surface, allowing for highly sensitive measurements of enzymatic activity. The technology enhances Raman signals in a reproducible manner, enabling fast detection of protease and enzyme activity, such as Prostate Specific Antigen (paPSA), in real-time at picomolar sensitivity levels. Experiments conducted on extracellular fluid (ECF) from paPSA-positive cells demonstrate the NPR's capability for specific detection in complex bio-fluid backgrounds, achieving real-time single-step detection in very small sample volumes.
