Fig. 8. Demonstration of PEG-PAM coating technology of hip implant in operating room.

PEG, PAM, photoinitiators are pre-weighted into a container. Chloroform is supplied at the appropriate volume to make a 6% solution of polymers. Pre-weighted antibiotics are thoroughly mixed with the dissolved polymers and either added to a sprayer apparatus or in a container to be painted. The polymer + antibiotic mix is then evenly applied to the implant surface. In this example, the antibiotic is red and easily seen on the implant surface. If needed a biocompatible dye can be added to the mixture for visualization. Following complete coverage, the implant is UV cured for two minutes.
