Life in Your Hand: Diagnose Yourself with Handheld Electronic Molecular Biosensors for Disease Biomarkers

Date: April 29, 2025

Time:  1 p.m.

About this Seminar

We all want to know: “Am I sick, Will I get sick, Will I be cured?” Currently, the fundamental causes for diseases are imprecise and treatments are still evolving. An early and precise diagnosis is our best hope. For personalized mass scale diagnoses, we need digital diagnosis tools and devices which are easy, less invasive, precise and can be performed at home, at POC and at hospital. Our innovative enabling nano-biotechnology provides tangible hope. Dr. Lal will discuss his new digital diagnostic platform which allows testing by ourselves for diseases and infections at our own time and place. Lal’s device consists of nucleic acid probes (aptamers) and graphene FET electrical recording sensors. G-FET sensor has a single electron charge transfer sensitivity during analyte-probe interactions and aptamer probes attain highest specificity by 3D conformation-based interaction with an analyte. As such, his team’s molecular diagnostics has three unique features they call “10,10.10” (ten minutes, ten dollars, ten times better than any available tests).
