Nano Tech-mod
Inverse Opal (IO), with biocompatibility, can be applied to optical nanostructures for better vision. For instance, the deformable and conformal silk hydrogel inverse opals may provide night vision or IR vision to humans. The hydrogel silk is produced with molucules under UV exposure.

OBJECTIVES
Photonic crystals are composed of porous nanostructures. The small feature size of these structures can be designed for a myriad of uses, from structural color to tunable wetting.
Concept
Inverse Opal (IO), with biocompatibility, can be applied to optical nanostructures for better vision. For instance, the deformable and conformal silk hydrogel inverse opals may provide night vision or IR vision to humans. The hydrogel silk is produced with molucules under UV exposure. One of the precedent is the tapetum lucidum of the cat which can reflect the incoming light to the retina, enhancing visibility. Inspired by this, we want to explore artificial ocular prostheses to complement human night vision.
