Fluorescence spectroscopy for the detection of tongue carcinoma - validation in an animal model
(Spie-soc Photoptical Instrumentation Engineers, 2014)
Re-absorption and scattering of chlorophyll fluorescence in canopies: A revised approach
(Elsevier Science Inc., 2020-09)
The measurement of chlorophyll fluorescence in remote way represents a tool that is becoming increasingly important in relation to the diagnosis of plant health and carbon budget on the planet. However, the detection of ...
Effect of different artificial aging protocol-son fluorescence of resin composites
(2018-01-01)
This study evaluated the effect of different artificial aging on fluorescence of resin composites. Forty-five cylindrical specimens (6mm in diameter and 1mm thick) were made of each resin composite: IPS Empress Direct, ...
Automated flow system for sildenafil enrichment using surfactant coated solid-phase with fluorescence detection
(Elsevier Science, 2012-08)
In this work, Amberlite XAD-1180 resin is used for on-line surfactant-mediated pre-concentration of sildenafil as a prior step for its fluorescent detection. In order to activate the column for sildenafil pre-concentration, ...
