Aptasensors Based on Whispering Gallery Mode Resonators [PDF]
Biosensors, 2016 In this paper, we review the literature on optical evanescent field sensing in resonant cavities where aptamers are used as biochemical receptors. The combined advantages of highly sensitive whispering gallery mode resonator (WGMR)-based transducers, and of the unique properties of aptamers make this approach extremely interesting in the medical field,

Whispering-Gallery Mode Resonators for Detecting Cancer [PDF]
Sensors, 2017 Optical resonators are sensors well known for their high sensitivity and fast response time. These sensors have a wide range of applications, including in the biomedical fields, and cancer detection is one such promising application. Sensor diagnosis currently has many limitations, such as being expensive, highly invasive, and time-consuming.

Whispering Gallery‐Mode Microdroplet Tensiometry [PDF]
Advanced Photonics Research, 2021 Droplets are ideally suited to support high‐Q‐factor whispering gallery modes (WGMs) due to their perfectly smooth surface. WGMs enable extremely precise measurements of the droplet properties such as size and shape. Herein, a simple, fast, and very precise technique to measure interfacial tension (IFT) between two immiscible liquids based on WGMs is ...

Whispering gallery modes for a transmission problem [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2023 We construct a specific family of eigenfunctions for a Laplace operator with coefficients having a jump across an interface. These eigenfunctions have an exponential concentration arbitrarily close to the interface, and therefore could be considered as whispering gallery modes. The proof is based on an appropriate Agmon estimate.
