...this is closer to the 405nm spectrum! Any lower wavelength, and your eyes would bleed UV tears. Kidding—this is not the logic behind our team t-shirt color. Rather, we aim to match the calcium indicator fluorescent blue in the state of bound and unbound calcium ions when excited by UV-light. We considered going for 355nm wavelength t-shirts (the wavelength spectra of our UV-LED excitation source), but as you know...the human eye cannot detect 355nm light, and we don't want to wear invisible shirts :)
We are very appreciative of our supporters!
