Today I spent some time on a draft of one of my cover art projects, which is going to be submitted with an article to the Journal of Inorganic Biochemistry. What's happening is that this big honking molecule acts like a cage for zinc that can distract it from its usual biological endeavors. However, if the molecule is exposed to a certain wavelength of light, photolysis occurs, which means that a bond breaks and the molecule separates into fragments that are no longer strong enough to contain zinc. Being able to control zinc concentration in a time-dependent manner can hopefully answer some interesting questions about neurobiology!
