ALEXANDRIA, Va., June 2 -- United States Patent no. 12,644,833, issued on June 2, was assigned to Purdue Research Foundation (Lafayette, Ind.).
"Depth-resolved mid-infrared photothermal imaging of living cells and organisms with sub-micron spatial resolution" was invented by Delong Zhang (Brighton, Mass.) and Ji-Xin Cheng (Newton, Mass.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods for sensing vibrational absorption induced photothermal effect via a visible light source. A Mid-infrared photothermal probe (MI-PTP, or MIP) approach achieves 10 mM detection sensitivity and sub-micron lateral spatial resolution. Such performance exceeds the diffraction limit of infrared microscopy and allows...
