fotodünaamiline

Fotodünaamiline refers to processes or phenomena that are activated or influenced by light. This term is commonly used in scientific contexts, particularly in photochemistry and photobiology. In photochemistry, fotodünaamiline reactions involve molecules absorbing light energy and undergoing chemical changes. This can lead to the formation of new chemical bonds, the breaking of existing ones, or the rearrangement of atoms within a molecule. Examples include photosynthesis in plants, where light energy is converted into chemical energy, and the degradation of certain materials upon exposure to sunlight.

In photobiology, fotodünaamiline effects relate to how living organisms respond to light. This can encompass a wide range of biological processes, from vision, where photoreceptor cells in the eye detect light, to phototropism in plants, where growth is directed towards a light source. Another significant area is photodynamic therapy (PDT), a medical treatment that uses light-activated drugs to destroy abnormal cells, such as cancer cells. The term emphasizes the crucial role of light as an energy source or trigger for these transformations.
