MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202621053545 A) filed by Sage University on April 27, 2026, for Apparatus And Method For Detecting Particulate Residues On Biological Surface.
Inventors include Dr. Prashant Jain; Ms. Sakshi Agrawal; Prapti Shukla; Suryaa. S; Abhishek Singh; Kairav Mishra; and Himesh Parmar.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: ABSTRACT The present disclosure relates to apparatus and methods for detecting particulate residues on biological surfaces. The apparatus (102) includes a first detector assembly (104) performing laser-induced breakdown spectroscopy and a second detector assembly (106) performing X-ray fluorescence spectroscopy on independent physical principles. A hardware processor (110) acquires elemental concentrations from both assemblies, compares them to generate a concordance score, and issues a verification flag when the score falls below a predetermined threshold. A hardware security element (108), comprising a secure key storage area, an asymmetric cryptographic signing engine (112), and a non-transitory storage medium (114), receives a data packet containing the elemental concentrations, concordance score, and verification flag. The asymmetric cryptographic signing engine (112) generates a cryptographic signature on the data packet, storing a signed evidence record on the non-transitory storage medium (114) that remains independently verifiable against post-measurement alteration.
