Neurochemical signals like dopamine (DA) play a crucial role in a variety of brain functions through intricate interactions with other neuromodulators and intracellular signaling pathways. However, studying these complex networks has been hindered by the challenge of detecting multiple neurochemicals simultaneously. To overcome this limitation, we developed a single-protein chemigenetic DA sensor, HaloDA1.

A single-chromophore-based photoactive agent (MB-DOPA) capable of rapid sensing of nanomolar hypochlorous acid (HOCl) and in-situ generating photocytotoxicity to cancer cells was developed using dopamine moiety as the recognition unit and methylene blue (MB) moiety as the fluorescence signaling unit. Specifically, HOCl triggered conversion of the nonfluorescent MB-DOPA to MB enabling far-red fluorescence emission (λ ∼ 683 nm) and additional ability to photogenerate O species. Owing to the catechol nature of dopamine characterized with strong electron-donating property, MB-DOPA underwent HOCl-mediated conversion with response time of ∼20 s and a strong fluorescence OFF-to-ON contrast by a factor of more than 3000.

The influence on the development of the outer segments of the rat retina of far red and red light in different sequences was investigated. The far red treatment appeared to be dominating, and for animals treated with far red light first, further treatment of red light could not bring the outer segment growth back to normal. The treatments also initiated different dopamine uptakes in the retinas.
