“…Importantly, collagen sponges are already used in clinical practice for bone regeneration, so incorporation of this nanosilicate/growth factor system into a pre-established material could expedite clinical translation. Moreover, nanosilicates can also be combined with various ranges of natural and synthetic polymeric hydrogel systems including gelatin, 19,51 kappa carrageenan, 36,52 and poly(ethylene oxide) 53 for sustained and prolonged delivery of therapeutic proteins. These nanocomposite systems have been investigated for both injectable systems 54 and 3D printed constructs.…”
