A Systematic Study of Laser‐Engineered Fluorescence in Carbon Black

Advanced Photonics Research, 2022
The feasibility of laser‐engineered fluorescence emission from carbon black (CB) with three laser sources of different wavelengths—660 nm (red), 532 nm (green), and 405 nm (blue) is demonstrated. From which the 660 nm focused laser beam produces the most

Optical Characterization of Ciprofloxacin Photolytic Degradation by UV-Pulsed Laser Radiation

Molecules, 2021
Ciprofloxacin is one of the most prescribed antibiotics in treating bacterial infections, becoming an important pollutant of the wastewaters. Moreover, ciprofloxacin is hard to be destroyed by conventional water treatment processes; therefore, efficient ...

Effectiveness of laser fluorescence–based device in detecting the extent of re-mineralisation in primary teeth compared to the conventional method: An In vitro study

Indian Journal of Dental Research, 2022
Background: Laser fluorescence (LF)–based clinical device DIAGNOdent™ is at present being used to detect caries. Can the same be used to detect therapeutic remineralisation of early white spot lesions?

Methods of Caries Incipient Well-timed Diagnostics

Česká Stomatologie a Praktické Zubní Lékařství, 2011
Caries incipient is characterized by subsurface demineralization of enamel. Optimal fluoridation with adequate oral hygiene and correction of diet can stop caries's progress or even lead to remineralization of lesion.

Applications of Laser-Induced Fluorescence in Medicine

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. This article presents examples of proprietary applications of laser-induced fluorescence (LIF) in medicine with ...
