Rapid and sensitive label-free sensors are needed for many biochemical applications including early diagnostics and prognostics, monitoring food and water quality, chemical threat sensing, and early ...

Figure 1. Overview of FLOWER based photothermal microscopy system. A schematic illustration of the photothermal microscopy setup. The pump light travels through free space, guided by a galvo mirror ...

Microtoroid resonators, when paired with noise reduction via the frequency locked whispering evanescent resonator technique, can detect zeptomolar concentrations and single molecules. This protocol ...

Resonators are devices that exhibit resonance, a phenomenon where a system oscillates with greater amplitude at specific frequencies. In the context of nanotechnology, resonators are nanoscale ...

USA, May 14, 2024 / EINPresswire.com / -- Microtoroid resonators are one of the most sensitive biochemical sensors, capable of detecting single molecules. Light is most commonly coupled into these ...
