| 1. An optically controlled microfluidic chip comprising:
(a) a reservoir containing a fluid;
(b) an aperture, wherein said fluid is capable of emitting from said reservoir through said aperture; and
(c) an optical control for sensing light and regulating the emission of said fluid through said aperture based on an amount
of light received,
wherein said fluid is emitted from said reservoir through said aperture by diffusion when said optical control is not illuminated,
and wherein said optical control reduces the emission of said fluid in response to said received light.
