Schematic of the swelling behavior of the CdTe QD PA hydrogel hybrid material utilized in a microfluidic valve (a). Increase in fluid flow as a result of changing pH from 10 to 2 (b). Closed valve with swollen and photoluminescent hybrid material under white light (c) and UV-light (d). Opened valve with shrunken and non-photoluminescent hybrid material under day light (e) and UV-light (f)
