Photodynamic dyes

Definition

Dyes that are capable of generating reactive oxygen species (ROS) upon exposure to light, leading to the destruction or inactivation of target organisms, cells, or viruses. While not directly related to entomology or arachnology, these dyes can be used in studies involving the control of pests or in research related to insect or arachnid physiology.

Etymology

From Greek 'photo-', meaning 'light', and 'dynamic' meaning 'moving' or 'active'.

Example

Photodynamic dyes are used in various applications, including medical treatments like photodynamic therapy for cancer.

Related Terms

• Photodynamic action
• ROS
• Light activation

Usage Notes

Photodynamic dyes often exhibit specific absorption spectra and require specific wavelengths of light for their activity. In entomology or arachnology, they might be used in research involving pest control or physiological studies.
