Applications of Laser-Induced Fluorescence in Medicine [PDF]

Sensors, 2022
Fluorescence is the most sensitive spectroscopic method of analysis and fluorescence methods. However, classical analysis requires sampling. There are new needs for real-time analyses of biological materials, without the need for sampling.

In Situ Femtosecond-Laser-Induced Fluorophores on Surface of Polyvinyl Alcohol for H₂O/Co²⁺ Sensing and Data Security

Sensors, 2021
In situ fluorophores were induced on polyvinyl alcohol (PVA) bulk materials by direct femtosecond laser writing. The generation of fluorophores was ascribed to localized laser-assisted carbonization.
