Pd-porphyrins are used as cross-linkers to generate an oxygen-responsive polyamide hydrogel. The implantable hydrogel is stable in vivo for weeks, biocompatible, and the high density of the Pd-porphyrin enables transdermal detection. By changing Pd chelation for Cu and free base porphyrins, an intensity-matched companion hydrogel is developed for a ratiometric sensing strategy.
