Genetically engineered protein calmodulin (CaM) was utilized as a model hinge-motion binding protein for the development of chemically tunable microlenses. An alternative method for the creation of microlenses by providing a one-step fabrication method for chemically tunable stimuli-responsive hydrogen microdomes were presented. The applications of these microlenses in the field of micro-optics and biosensing were also demonstrated. Stimuli-responsive hydrogels are applied in bioseparations, sensors, actuators, drug delivery, and biomedicine, because of their ability to respond reversible to an external stimulus that creates a measurable effect on the properties of the material. The practical applications of these microlenses are restricted to multimeric proteins that binds to multiple recognition elements on the surface of the hydrogel, thus altering the crosslinking of the surface of the microlens.
