Critical review on oligonucleotide based detection with optical microresonators

Our critical review is published in Lab on a Chip. The use of Whispering Gallery Mode (WGM) type optical microresonators as chemical and biological sensors have created a significant interest accompanied with considerable excitement in the broad field of biosensing, particularly by virtue of their extremely high sensitivity. These microstructures form cavities in which light is temporarily trapped within, and this trapping is highly sensitive towards the perturbations occurring at …
