US Patent Issued to Trustees of Boston University on Nov. 11 for "Widefield interferometric defocus-enhanced (WIDE) mid-infrared (MIR) photothermal microscopy" (Massachusetts Inventors)

ALEXANDRIA, Va., Nov. 11 -- United States Patent no. 12,467,842, issued on Nov. 11, was assigned to Trustees of Boston University (Boston).

"Widefield interferometric defocus-enhanced (WIDE) mid-infrared (MIR) photothermal microscopy" was invented by Ji-Xin Cheng (Newton, Mass.) and Qing Xia (Boston).

According to the abstract* released by the U.S. Patent & Trademark Office: "A wide-field microscopy system and method for imaging a sample include directing infrared light onto the sample to selectively heat the sample.
