Optical biosensors have many advantages over traditional analytical methods. They enable the identification of several biological and chemical compounds directly, instantly, and without the need of labels. Their benefits include excellent specificity, sensitivity, compact size, and low cost. In this review, the main focus is placed on the nucleic acid-based optical biosensor technologies, including colorimetric, fluorescence, surface plasmon resonance (SPR), Evanescent-Wave Optical, Fiber optic and bioluminescent optical fibre. The fundamentals of each type of biosensor are briefly explained, and particular emphasis has been placed on the achievements which have been gained in the last decade on the field of diagnosis of infectious viral diseases. Concluding remarks concerning the perspectives of further developments are discussed.

“…Whispering gallery mode (WGM) microresonators have shown immense potential for the detection of various environmental targets such as temperature 1 , pressure 2 , and humidity 3 as well as biological targets [4][5][6][7] . The enormous sensitivity of the WGM platform comes from the resonators ability to trap and confine light in micron-sized circular geometries utilizing constructive interference 8 .…”

Whispering Gallery Mode (WGM) microresonators are a class of optical sensors with the ability to trap and confine light under optical resonance conditions. Typically, this resonance is excited inside a WGM resonator using expensive and bulky tunable diode lasers, which can be a limiting factor in low-resource settings and in developing economies. In the manuscript, we describe a method of “reverse tuning” to modify the resonance conditions, paving the way for lower cost WGM excitation and ultimately lower cost sensing. We demonstrate three different methods of reverse tuning the WGM using temperature, pressure, and refractive index in a microbubble resonator (MBR), a subclass of WGM sensors that is particularly well-suited for reverse tuning using the three aforementioned methods. By reducing the cost of the MBR platform through reverse tuning, we can make these ultra-sensitive devices more practical and accessible in low-resource settings.
