"light-sensitized common polymers and micro-LED light sources... self-enclosed, porous, high-resolution channels carrying aqueous solutions and separating small biomolecules... photolithography technique... display structural color linked to pore size... allow patients to monitor vital health markers wearing small patch... relevant biomolecules such as insulin and the SARS-COV2 shell protein were compatible with our channels. I think that diagnostic devices are a promising future for this technology"
