Figure 1.

An overview of different platforms that are engineered to release NO (counterclockwise from center: liposomes, micelles, dendrimers, particles, metal–organic frameworks, hydrogels, freestanding films, implantable devices). NO can be delivered from encapsulated NO donors, which carry NO and stabilize the radical until release is required. NO can also be delivered via enzymatic conversion of custom‐made synthetic NO prodrugs or endogenous NO donors (using natural enzymes or nonproteinaceous enzyme mimics).
