Fluorescence Enhancement Effect of TiO2 Nanoparticles and Application for Photodynamic Diagnosis. [PDF]
Int J Mol Sci, 2019 Photodynamic diagnosis (PDD) can improve diagnostic accuracy by using PDD agents such as 5-aminolevulinic acid (ALA). However, the weakness and photobleaching of fluorescence of PDD agents may lead to insufficient fluorescence visibility for the ...
