TL;DR: In this paper, a brief review strongly recommends the application of saliva/tears and exhaled breath as clinical samples using technics such as highperformance liquid chromatography-laser-induced fluorescence, photoacoustic spectroscopy, and e-Nose, respectively, for the fast diagnosis of viral infections.

TL;DR: In this paper, a comprehensive account of applications of tear analysis using different techniques, their comparison and overall progress achieved till now is presented, with a special emphasis on eye diseases, and the authors recommend tear fluid as a reliable clinical sample to be probed by highly sensitive optical techniques to diagnose different health conditions.

TL;DR: The potential of optical spectroscopy based techniques for regular screening and early diagnosis of “Killer” diseases (various types of cancers, cardiovascular diseases, etc.) is discussed with focus on routine use under low-resource settings.

TL;DR: In this paper , a review of the current progress and prospects in biomarker research for the diagnosis of cardiovascular diseases is presented, which discusses the analysis of clinical samples such as whole blood, blood serum, and other body fluids using techniques like high-performance liquid chromatography-LASER/LED-induced fluorescence, Raman spectroscopy, mainly, optical methods, combined with nanotechnology and micro-fluidic technologies, to probe patterns of multiple markers (marker signatures) as compared to conventional techniques.
