Lossy Mode Resonance Sensors in Uncoated Optical Fiber

IEEE Sensors Journal, 2023
This work demonstrates that the use of an unconventional optical fiber allows for generating lossy mode resonances (LMRs), without the need for an external high refractive index (RI) thin film. The basic idea consists of using a few centimeters of an optical fiber having a large core and cladding with higher RI, which is spliced between two multimode ...

Generation of leaky mode resonance and lossy mode resonance with the same optical platform

Optics Express
Leaky mode resonance (L e MR) and lossy mode resonance (L o MR) refer to two different surface waves but are easily confused. Herein, we comprehensively investigated the excitation mechanism and sensing performance of both L e

Electrochemical lossy mode resonance for detection of manganese ions

Sensors and Actuators B: Chemical, 2023
In this work we propose electrochemical lossy mode resonance (eLMR) as a powerful method for the detection of manganese (Mn) ions. The sensor is based on a simple planar waveguide (sodasingle bondlime glass coverslip) coated with a thin layer of indium tin oxide (ITO) to obtain an optical resonance effect.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
