MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202521103274 A) filed by D. Y. Patil Education Society, Kolhapur, Maharashtra, on Oct. 27, 2025, for 'method for detection of ovarian cancer biomarker using carbon quantum dots.'
Inventor(s) include Prof. Dr. Arpita Pandey-Tiwari; Ms. Pranoti A. Kamble; and Prof. Dr. Chandrakant Dnyandev Lokhande.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates method for ovarian cancer biomarker detection by carbon quantum dots(CQDs). The invention is unique in detection of breast cancer biomarker using Antibody CA-125 conjugated L-CQDs from human serum samples. The ovarian cancer biomarker is detected by decrease in fluorescence intensity peak as monitored in fluorescence spectroscopy. The claimed ovarian cancer antigen detection method shows many advantages including label free, rapid, simple, cost-effective, high sensitivity which helps to overcome the limitations of high cost and time consumption exhibited by many other traditional clinical assays for cancer detection using biomarker from human serum."
