His innovative work has implications in various industries, particularly in chemical mechanical planarization and molecular interaction detection.
Latest Patents
One of Gupta's latest patents focuses on polymeric microgels for chemical mechanical planarization (CMP) processing. This invention involves the preparation of organic-inorganic composites as colloidal particles of a cross-linked, thermally responsive polymer. Hybrid PNIPAM-polysiloxane particles and composite polymeric particles with embedded nanoparticles of inorganic metal-oxides such as CeO2 and TiO2 were formed. The incorporation of unaggregated nanoparticles was promoted using temperature-responsive microspherical gels of N-isopropylacrylamide (NIPAM) with interpenetrating linear chains of poly(acrylic acid) (PAA). Experimental results indicated that the planarization of silicon oxide wafers using these hybrid particles exhibited lower topographical variations and surface roughness compared to slurries consisting solely of silica or ceria nanoparticles, while achieving similar removal rates and better or comparable frictional characteristics.
Another notable patent by Gupta involves optical amplification of molecular interactions using liquid crystals. This invention provides a method for detecting an analyte by contacting it with a recognition moiety. This interaction causes a portion of mesogens proximate to the recognition moiety to switch orientations, which can then be detected, allowing for the identification of the analyte.
