Abstract: Ongoing changes in the analytical field are demanding novel technological diagnostic tools that could enable a quick, accurate, reliable and cost-effective testing avoiding the expensive, complex and time-consuming procedures typically employed in standard analytical evaluation. The result of those tests open the way to implement appropriate actions in time, leading to an improved socioeconomic outcome. Optical biochemical and chemical sensors have positioned themselves as one of the best options to be such novel technological diagnostics tools. The unique characteristics of optical sensing as its inherently high sensitivity, compactness, reliability, electromagnetic immunity, easy interconnectivity, possibility of remote sensing, wide detection range using a minimum volume of sample and reagents, and low cost, have promoted them as the preferable solution. Main applications of this technology will be in clinical diagnostics, but the technology will be beneficial in other impactful fields, as genomics, proteomics, pharmacology, health care, environmental monitoring, food analysis, agriculture, intracellular sensing, defense, and security, among others.
