Photosensitizers are light absorbers that alter the course of a photochemical reaction. They usually are catalysts. [1] . They can function by many mechanisms, sometimes they donate an …

photosensitization, the process of initiating a reaction through the use of a substance capable of absorbing light and transferring the energy to the desired reactants. The technique is …

PDT uses photosensitizers (PSs, non-toxic dyes) that are activated by absorption of visible light to initially form the excited singlet state, followed by transition to the long-lived excited triplet state.

Photosensitized molecular oxygen is a powerfully oxidative species that severely hampers the photosynthetic efficiency of plants and causes health problems such as cataracts in humans.

2021年9月1日 · The concept of photosensitization had its origins in the serendipitous discovery in the 19th century that dye molecules could enhance the spectral range of photographic emulsions.

Photosensitization reactions have been demonstrated to be largely responsible for the deleterious biological effects of UV and visible radiation, as well as for the curative actions of …

Photosensitized reactions refer to indirect photochemical reactions in which a photosensitizer molecule absorbs light and induces chemical changes in another chemical species, leading to …

Photosensitization is a reaction to light that is mediated by a light-absorbing molecule, which is not the ultimate target. Photosensitization can involve reactions within living cells or tissues, or …

Photosensitization reactions have been demonstrated to be largely responsible for the deleterious biological effects of UV and visible radiation, as well as for the curative actions of …

Photosensitization involves the absorption of radiation by a strongly absorbing substance, the photosensitizer and its collisional transfer to another substance which is non-absorbing at the …
