Figure 1

Schematic illustration of the bioinspired multifunctional MNs with adhesive and antibacterial abilities. The MNs have a mussel byssus-inspired PDA hydrogel as the base and are loaded with polymyxin derived from P. polymyxa. Each MN is surrounded with a circle of concave chambers, which mimic the suction cups of octopi.
