Light-sensitive dyes are special chemicals that change their properties when exposed to light. These dyes can absorb specific wavelengths of light and then release energy in different forms, such as heat or fluorescence. They are commonly used in various applications, including photography, where they help capture images, and in solar cells, where they improve energy conversion. These dyes are also important in scientific research and medical diagnostics. For example, they can be used in bioluminescent imaging to visualize biological processes in living organisms. Their ability to respond to light makes them valuable tools in both industry and science.
