New Disease Biomarkers Data Have Been Reported by Researchers at Pt. Ravishankar Shukla University (Nanomaterial-enabled Portable Paper-based Colorimetric and Fluorometric Devices: Progress In Point-of-care Diagnosis).

Researchers at Pt. Ravishankar Shukla University in Raipur, India have published a review paper on the development of colorimetric and fluorometric paper-based analytical devices (PADs) for rapid point-of-care diagnosis of disease biomarkers. The paper discusses the principles of colorimetry and fluorometry and their application in detecting various biomolecules. Metal nanoparticles and quantum dots are highlighted as versatile sensing probes in these devices. The review provides an overview of the fabrication techniques, integration with portable devices, and diverse applications of these paper-based diagnostic platforms. The researchers conclude that the combination of metal nanoparticles and quantum dots with paper-based devices shows promise for advancing point-of-care diagnostics. [Extracted from the article]
