The Brown researchers have created nanoscale surfaces for implanted materials that mimic the contours of natural skin, which attract skin cells that, over time, build a natural seal against bacterial invasion. The group also created a molecular chain to sprinkle skin-growing proteins on the implant to hasten skin growth. Laboratory tests showed a near doubling of skin cell density on the implant surface, with the keratinocyte density, within five days, reaching a point at which the skin layer bridging the abutment and the body had been created. According to Thomas Webster, an associate professor of engineering and orthopedics, &#8220;You definitely have a complete layer of skin. There&#8217;s no more gap for the bacteria to go through.&#8221; The team&#8217;s next step is to perform in vivo studies. Human trials could follow successful in vivo studies, although Webster says such trials could be years away.
