VIT-A.P. researchers demonstrate low-cost photonic tech for non-invasive disease screening

VIJAYAWADA Scientists from CATS Global (CASTLE Advanced Technologies and Systems), Nashik, Maharashtra, and VIT-A.P. University, Amaravati, Andhra Pradesh, have developed and demonstrated an innovative, low-cost optical sensing approach that could pave the way for affordable, non-invasive disease screening through breath analysis.

According to a press release from the VIT-A.P., the research article titled ‘Photonic elastic-backscatter fingerprinting of exhaled-breath metabolites for non-invasive disease screening’, authored by professors Rao Tatavarti, Sridevi Nadimpalli and P. Arulmozhivarman Pachiyappan, was published on November 6, 2026, in the international journal Scientific Reports, published by Springer Nature.

The study explores a photonic sensing technique that uses a simple, low-power laser and a position-sensitive optical detector to identify distinctive optical signatures associated with disease-related chemical compounds.
