Why in news
Scientists from CATS Global and VIT-A.P. University developed a low-cost optical sensing approach to screen diseases through non-invasive breath analysis.
Background
The study, published in Scientific Reports, utilizes a low-power laser to identify chemical signatures of diseases. The technology aims to replace expensive laboratory instruments with compact systems that detect variations in volatile organic compounds.
Facts for Prelims
- S&TThe sensing method uses a low-power laser to identify chemical signatures of diseases.
- FactThe technology detects variations in volatile organic compounds (VOCs) in human breath.
- BodyThe research was a collaboration between CATS Global and VIT-A.P. University.
