Common nanocomposite hydrogel wound dressings.

Nanocomposites	Hydrogel Resin	Wound Types	Advantages	Challenges	Ref.
Silver nanoparticles (AgNPs)	Chitosan hydrogel	Acute wounds	Self-cleaning and antibacterial properties.	Crosslinking and 3D printing	[180,181,182]
AgNPs	Chitosan and hyaluronic acid	Diabetic foot ulcers	Resisting antibiotic bacteria	Crosslinking and fabrication of the nanomaterial	[183]
AgNPs	Surface-grafted collagen	Acute wounds	Inhibiting of bacterial growth and increase in membrane water absorption	Agglomeration	[184]
TiO2	Collagen	In vivo and in vitro excision wounds.	Accelerate healing	Crosslinking and fabrication of the nanomaterial	[185]
Nano ZnO	Chitin hydrogel	Acute and chronic wounds	Enhanced swelling, blood clotting and antibacterial effect. Absorbing large volumes wound exudate. Controlled degradation, enhanced blood clotting and excellent platelet activation.	Fabrication of the nanomaterial	[178]
Nano ZnO	Nitrocellulose	Hard to cover cut wounds	Flexibility, softness, transparency and conformability.	3D printing	[186]
Gelatin oxidized starch nanofibers	Lawsonia inermis (henna)	Treating second degree burn	Enhanced fibroblast attachment, proliferation, collagen secretion and antibacterial activity.	3D printing	[187]
