Potential Wound Healing of PLGA Nanoparticles Containing a Novel L-Carnitine–GHK Peptide Conjugate

Figure 4

(a) Effect of materials and NPs on wound healing. Wounds closure over time was measured as percent of original area: 1 - Untreated; 2 - L-carnitine; 3 - PLGA; 4 - GHK; 5 - GHK-L-carnitine conjugate; and 6 - Conjugate-loaded PLGA NPs.
