Desirable characteristics of drug-eluting scaffolds adapted and updated from [

| Desirable characteristics of growth factor-eluting scaffolds (adapted from [24]) | |
| Low immunogenic and antigenic response. | | Controllable breakdown into benign biodegradable products occurring contemporaneously with new bone formation. | | Good mechanical properties during breakdown, while retaining a porous structure capable of cellular infiltration | | Good “biocompatibility”*. | | Ability to load a growth factor with high efficiency and elute a therapeutical dosage over a sustained period of time relevant to the application. | | Ability to be readily sterilised without either loss of mechanical function or denaturation of delivered drug. | | Adaptability to wound site, surgical malleability. | | Relatively long shelf-life, allowing for ease of access to a surgeon. | |

*We use the Williams definition of “biocompatibility” found in [38].
