In vivo results. In the subcutaneous implant model (a), copper addition (zein/CuBG) caused the inhibition of the induced infection (b) in comparison with zein (control) and zein/BG. All zein (c-d-e), zein/BG (f-g-h) and zein/CuBG (i-j-k) coatings supported similar tissue thickness formation of about 50–55 μm. Vessels count (d-g-j) confirmed that zein/CuBG coatings recruited the highest number of vessels (indicated by red arrows) that were verified as newly formed (<50 μm) by the diameter spread evaluation (l).
