PHOTOSENSITIZERS - Names and Identifiers
PHOTOSENSITIZERS - Introduction
PHOTOSENSITIZERS are a class of substances that can absorb light energy and convert it into chemical energy. They have the following properties:
1. Absorption of light of a specific wavelength: The PHOTOSENSITIZERS absorbs light energy in a specific wavelength range, and its absorption peak is usually located in the ultraviolet or visible light region.
2. has an excited state: when the PHOTOSENSITIZERS absorbs light energy, its electrons will transition to an excited state, that is, a high-energy state.
3. chemical reactivity: excited PHOTOSENSITIZERS may react with other substances, such as oxidation, reduction, photolysis, etc.
PHOTOSENSITIZERS are widely used, some of the main uses include:
1. Chemical and biological research: PHOTOSENSITIZERS can be used as exciters and energy transfer receptors for the study of photochemical reactions, energy transfer and photobiology.
2. Chemical synthesis: PHOTOSENSITIZERS plays a catalytic role in photocatalytic reactions and can be used in organic synthesis reactions, such as photo-oxidation, photo-reduction, photo-polymerization, etc.
3. Medicine: Certain PHOTOSENSITIZERS are used in photodynamic therapy, which uses the properties of PHOTOSENSITIZERS to generate reactive oxygen species in the body to destroy cancer cells or treat other diseases.
PHOTOSENSITIZERS can be prepared in a variety of ways, common methods include chemical synthesis, natural extraction and genetic engineering. During the preparation process, attention should be paid to the purity and stability of the PHOTOSENSITIZERS to ensure its effectiveness and safety.
When using the PHOTOSENSITIZERS, the safety information to be aware of includes:
1. Avoid excessive exposure: The dose must be strictly controlled when using PHOTOSENSITIZERS, and avoid contact with unprotected skin or eyes.
2. photolysis effect: some PHOTOSENSITIZERS may produce photolysis effect when exposed to light, which needs to be stored and processed under the condition of avoiding light.
3. adverse reactions: individuals may be allergic to PHOTOSENSITIZERS or adverse reactions, such as skin inflammation, allergic reactions. Adequate testing and evaluation should be performed prior to use.
In general, the correct use of PHOTOSENSITIZERS and compliance with relevant safety procedures are essential. When using, you should read the product description carefully and take appropriate protective measures to ensure the safety of the experiment.
