Optical biosensors have exhibited worthwhile performance in detecting biological systems
and promoting significant advances in clinical diagnostics, drug discovery, food process …

The term whispering gallery mode (WGM) was first introduced to describe the curvilinear
propagation of sound waves under a cathedral dome. The physical concept has now been …

Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

The early detection of cancer can significantly reduce cancer mortality and saves lives. Thus,
a great deal of effort has been devoted to the exploration of new technologies to detect early …

We present a comprehensive overview of sensor technology exploiting optical whispering
gallery mode (WGM) resonances. After a short introduction we begin by detailing the …

Single-molecule detection has long relied on fluorescent labeling with high quantum-yield
fluorophores. Plasmon-enhanced detection circumvents the need for labeling by allowing …

This review article discusses progress in surface plasmon resonance (SPR) of two-
dimensional (2D) and three-dimensional (3D) chip-based nanostructure array patterns …

Optical systems combining balanced loss and gain provide a unique platform to implement
classical analogues of quantum systems described by non-Hermitian parity–time (PT) …

Optical whispering-gallery mode (WGM) microresonators, confining resonant photons in a
microscale volume for long periods of time, strongly enhance light-matter interactions …

Biosensing relies on the detection of molecules and their specific interactions. It is therefore
highly desirable to develop transducers exhibiting ultimate detection limits. Microcavities are …
