MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202611000874 A) filed by Nims University, Jaipur, Rajasthan, on Jan. 5, for 'isotachophoretic pad-serum separator.'
Inventor(s) include Gayatri Pandey; Akshat Pratap Singh; and Vaibhav Tamrakar.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "An isotachophoretic pad-serum separator (100) for pre-processing menstrual blood samples to obtain a low-viscosity, analyte-rich fraction suitable for diagnostic assays. The separator comprises a porous sample application pad (101) configured to receive the menstrual blood sample, an isotachophoretic microstrip (102) in fluidic communication with the pad, including a leading ion (LI) zone (102a) containing a first electrolyte salt and a trailing ion (TI) zone (102b) containing a second electrolyte salt of lower electrophoretic mobility, and a diagnostic test zone (103) positioned downstream of the microstrip. Upon hydration, the LI and TI zones generate an ionic gradient that separates charged analytes from viscous and cellular components, delivering a clarified fraction to the diagnostic test zone (103). The invention enables passive, power-free, and efficient serum extraction for use in hormonal, biomarker, or infectious disease assays, particularly adapted for field and home-based diagnostic applications."
