Reference

Synthetic polymer NPs

VEGF, PDGF, bFGF

Double emulsion

The system allowed spatiotemporal control of GF release, which promoted angiogenesis

Cardiovascular regeneration

70

Chitosan coated-BSA NPs

BMP-2

Modified desolvation

The chitosan coatings improved the stability of BSA NPs and realize the sustained release of BMP-2 for a long term

Bone regeneraiton

71

Heparin/chitosan/poly(γ-glutamic acid) NPs

FGF-2

Polyelectrolyte complex

Approximately 85% of the bound FGF-2 was released from the polysaccharide-based NPs within 48 h. After 48 h, there was very little GF release up to 72 h

Ischemic tissue regeneration

72

Biopolymer- coated liposomes

FGF-2

Modified emulsification- ultrasonication

The entrapment efficiency was 72 %, and the system realized the sustained release of EGF

Regenrative medicine application

73

Nanostructured lipid carriers (NLC)

EGF

Emulsification ultrasonication based method

The EGF-NLC promoted wound healing associated with number of arranged microvasculature, fibroblast functions, collagen deposition in full-thickness excisional model

Wound healing

74

Inorganic NPs

EGF

Copre-cipitation

The system showed receptor-mediated targeted delivery and high diagnostic potency

Therapy of brain tumor

75

Chitosan- functionalized MSNs

BMP-2

Templated sol-gel method

The initial burst release and following sustained release of BMP-2 is favorable to promote osteoblast differentiation and ectopic bone formation

Bone regeneration

76

Protein nanocapsules

VEGF

Aqueous assembly

The sustained released VEGF from nanocapsules resulted in enhanced vascular formation in vitro and in vivo

Angiogenesis

77

PLGA nanocapsules

BMP-2

Free-radical polymerization

Compared to the direct use of native BMP-2, sustained release of BMP-2 from the nanocarriers successfully enhanced bone formation with better bone quality and reduced the side effects
