Targeted and sustained delivery of biologicals to improve neovascularization has been focused on stimulation angiogenesis. The formation of collaterals however is hemodynamically much more efficient, but as a target of therapy has been under-utilized. Although there is good understanding of the molecular processes involving collateral formation and there are interesting drugable candidates, the need for targeting and sustained delivery is still an obstacle towards safe and effective treatment. Molecular targeting with nanoparticles of liposomes is promising and so are peri-vascularly delivered polymer-based protein reservoirs. These developments will lead to future arteriogenesis strategies that are adjunct to current revascularization.

Healing of diabetic wounds is significantly impeded by a complex environment comprising biofilm formation, excessive inflammation, and compromised angiogenic capacity, leading to a disordered physiological healing process. Restoration and maintenance of a normal and orderly healing process in diabetic wounds remain unmet therapeutic objectives. Herein, an innovative bimetal-phenolic network hydrogel system is designed with a concentric circular structure, enabling dual-drug delivery with differentiated release kinetics.
