A research team from the School of Physics’ Advanced Centre of Research in High Energy Material (ACRHEM) of the University of Hyderabad (UoH) announced on Tuesday, August 8, 2023, the development of a high “Q” Helmholtz Photoacoustic (PA) cell sensor with a movable piston arrangement for low-level detection of acetone biomarker.
The fabricated Helmholtz PA cell is made of aluminium and detecting acetone is a vital biomarker in diagnosing various diseases such as diabetes, asthma, and lung cancer.
“We have achieved unparalleled sensitivity, detecting acetone at levels as low as parts per trillion (PPT). This holds immense promise for non-invasive medical diagnostics and may revolutionise disease detection. It can also be used for detection of trace explosives and atmospheric pollutants, volatile solvents and others,” said ACRHEM’s A.K. Chaudhary and research scholar Arjun V.S. Kidavu.
