- Abstract
Hydrogels are gels with water as the dispersion medium and three-dimensional porous polymer networks cross-linked chemically or physically. The combination of drug-carrying nanoparticles with hydrogel-based delivery systems can achieve high targeting through hydrogels and prolong the duration of drug release by employing nanoparticles. The aldehyde groups in the polymer chain segments can react with amine groups in the skin tissue to prepare hydrogels with mucoadhesive properties, thus, enabling in situ polymerization of hydrogels adhering to wet biological tissue surfaces. These self-patterned hydrogels have layered wrinkled microstructures and interconnected ridges on their surfaces that improve the skin compliance and signal-to-noise ratio (SNR) of hydrogels, which allows hydrogel-based pressure sensors with high sensitivity and accurate sensing of dynamic pressure [[17]].
