“As the chromophoric part of the molecule is inserted deeper in the membrane, singlet oxygen is produced by photosensitization at a greater depth.”

“The search for new compounds with potential photosensitization activity for biological systems is relevant to the science of photobiology.”

“Thus it appears that PHP-mediated cytotoxicity proceeds through both membrane and mitochondrial photosensitization.”

“The onset of photosensitivity occurred following a sunlamp session in which the lamp exploded while being used.”

“Essential oils may cause photosensitivity, skin irritation or may sensitize the skin.”

“As with many psychoactive drugs, tachycardia is also prevalent with deliriant use, as is photosensitivity due to enlarged pupils.”

“It is metabolised by the skin cells' normal biochemical pathways within 48 hours and so does not lead to prolonged photosensitisation.”
