This project aims to develop prototypes of biofunctionalized prostheses for use in veterinary medicine containing formulations of rationally synthesized compounds (CRS) known to have antimicrobial activity for efficacy and toxicity tests in ex vivo and in vivo models. For the methodological development, pig ear skin was used for the penetrability study with a gray resin test piece containing 8-hydroxyquinoline (8-HQ). Immediately after skin preparation, the epidermal side of the sample was placed in contact with the prosthesis printed in gray resin containing 8-Hydroxyquinoline 10mg for a period of 6 hours. After this period, the skin was placed in formalin for a period of 20 days, then prepared for the production of slides for penetrability analysis. The method for determining antifungal activity was Disk Diffusion in Sabouraud agar. The prostheses were made based on the concept of planning, development and testing called “Do It Yourself” (DIY). The parts were modeled in free online software (“TinkerCAD”) and were made with gray resin in a 3D printer.
