Staphyloxanthin is prone to photobleaching under blue light irradiance. a) Absorption spectrum of crude STX extract (brown) and emission profile of a blue LED (black). b) Schematic illustration of a portable LED‐based wide‐field photobleaching device. c) Pictures of crude STX extract exposed to 460 nm light and ambient light at different time intervals. d) Absorption spectra of crude STX extract over different 460 nm light exposure time. e) OD of crude STX extract at 470 nm adapted from (d) over 460 nm light exposure time. Data points were fitted by Equation (1).
