Electrically Controlled Click‐Chemistry for Assembly of Bioactive Hydrogels on Diverse Micro‐ and Flexible Electrodes

Inside Cover: In article 2200557, Ivan Rusev Minev and co-workers use electrochemical method to assemble semi-synthetic hydrogels directly on electronically conductive surfaces by using an electrochemical-chemicalchemical (ECC) mechanism. Hydrogels consisting of poly (ethylene glycol) (PEG) heparin building blocks (functional biomolecule) are crosslinked spatially controlling the click reaction between their thiol maleimide moieties electro-assisted 3D printing method. The gels grown as coatings or 2D patterns ITO, gold, PtIr microelectrode.
