Optical Excitation in Life Science Research

In life science research, optical excitation plays an important role in many experiments, such as fluorescence microscopy and photoacoustic imaging. When light is shone on living tissues, certain substances can be excited and emit fluorescence or generate sound waves, which can then be used for analysis and diagnosis. However, the optimal excitation wavelength and intensity are often specific to each experiment and sample, making it necessary to carefully select and adjust the parameters for each experiment. In addition, the photo-toxicity of optical excitation should also be carefully considered, as it may cause damage to tissues and cells. Therefore, it is essential to use safe and effective optical equipment and methods in life science research to ensure accurate and reliable results.
