Scheme 1: Schematic illustrations of A-LIP-PEG for stimulating osteogenesis.

aSchematic illustration of A-LIP formation. b A-LIP, SH-PEG, and Ag + constructed by Ag–S coordination form an adhesive, liposome-laden, injectable, self-healing, and antibacterial hydrogel (A-LIP-PEG). c A-LIP-PEG was locally injected into an osteoporotic fracture and a bone marrow cavity, and the A-Lip released from A-LIP-PEG adhered to the lesion site in situ to release drugs.
