MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202621030724 A) filed by Sardar Vallabhbhai National Institute Of Technology, Surat, Gujarat, on March 13, for 'method for selective screening of imipramine using eu3+ ion-doped cr2ctx mxene qds.'
Inventor(s) include Suresh Kumar Kailasa; Pooja Dharni Dhar Singh; and Z. V. P. Murthy.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "Disclosed method (100) for selective screening of the antidepressant drug Imipramine (IMP) using Eu3+ ion-doped Cr2CTx MXene QDs comprising exfoliating Cr2AlC MAX phase to produce Cr2CTx MXene QDs by selective etching of Al using ZnCl2 as the etching agent. The method (100) further comprising obtaining a Cr2CTx MXene QDs colloidal dispersion solution upon sonicating a collected precipitate by centrifugation, dispersed in deionised water. Furthermore, the method (100) comprising adding EuCl3 solution to the obtained Cr2CTx MXene QDs colloidal dispersion solution to generate a mixture solution. Furthermore, the method (100) comprising obtaining Eu3+:Cr2CTx MXene QDs by vigorously stirring the mixture solution on a magnetic stirrer at an elevated temperature. Furthermore, the method (100) comprising sensing IMP, upon addition of IMP due to the obtained probe Eu3+:Cr2CTx MXene QDs, by employing ratiometric analysis on fluorescence spectral data of the probe Eu3+:Cr2CTx MXene QDs, before and after addition of the analyte IMP."
