Title: Innovations by Inventor Shamim Ahmad
Introduction
Shamim Ahmad is a notable inventor based in New Delhi, India. He has made significant contributions to the field of biosensors, particularly in the quantitative estimation of cholesterol and potassium levels in human blood serum. With a total of two patents to his name, his work showcases the intersection of technology and healthcare.
Latest Patents
One of Shamim Ahmad's latest patents is a potentiometric cholesterol sensor designed for the quantitative estimation of total cholesterol in human blood serum. This innovative sensor utilizes a molecular imprint of cholesterol, allowing for accurate measurements within the typical cholesterol range of 150-250 mg/dl found in human blood serum. The sensor device employs an Ion Selective Field Effect Transistor (ISFET) coated with a molecular imprint of cholesterol on the SiO+SiN dielectric gate, ensuring specific selectivity towards cholesterol amidst other organic constituents.
Another significant invention by Ahmad is a biosensor aimed at determining potassium concentration in human blood serum. This biosensor employs dibenzo-18-crown-6 (DB18C6) as an ionophore, which demonstrates excellent selectivity towards potassium, even in the presence of sodium at much higher concentrations. The invention reports the fabrication and characterization of an ISFET coated with a monolayer of crown ether, dissolved in chloroform, on the gate of the electrode, allowing for sensitive detection of potassium levels ranging from 137 to 200 mg/litre.
