A historical review of experimental imaging of the beating heart coronary microcirculation in vivo
Journal of Anatomy, Volume 242, Issue 1, Page 3-16, January 2023., 2023 Intravital imaging of the beating heart microcirculation in vivo has been challenging. The past 50 years has seen changes in ways to both stabilise and image the heart with a shift from learning about coronary vascular anatomy and physiology to the role of thromboinflammation and other microcirculatory disturbances in cardiovascular disease.

Optical humidity sensor based on a liquid whispering-gallery mode resonator [PDF]
arXiv, 2016 We experimentally demonstrate the use of a novel liquid state, whispering-gallery-mode optical resonator as a highly sensitive humidity sensor. The optical resonator used consists of a droplet made of glycerol, a transparent liquid that enables high optical quality factor, doped with rhodamine 6G, which acts as fluorescent emitter.

Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes
Advanced Optical Materials, EarlyView.This study explores spectrally tunable photonics barcodes using carbonized polymer dots (CPDs) based on whispering gallery mode (WGM) photoluminescence. CPDs offer wavelength‐dependent emission from visible to near‐infrared (NIR), thereby enabling variable WGM emissions.

Plasmonic random laser on an optical fiber tip [PDF]
arXiv, 2020 Random lasing occurs as the result of a coherent optical feedback from multiple scattering centers. Here, we demonstrate that plasmonic gold nanostars are efficient light scattering centers, exhibiting strong field enhancement at their nanotips, which assists a very narrow bandwidth and highly amplified coherent random lasing with a low lasing ...
