Thomas Webster, an associate engineering professor at Brown University, and Brown researcher Dongwoo Khang, along with Grace Park, a research scientist (and one of Webster's former PhD students) at Becton, Dickinson and Company, a Franklin Lakes, N.J.–medical technology firm, say they grew cartilage cells by placing chondrocytes (cartilage-forming cells) and carbon nanotubes together on a polycarbonate urethane surface. As expected, cartilage cells grew around the nanotubes, which are so strong that scientists now use them to reinforce plastic. Researchers say they hastened new cell production by sending electrical surges through the nanotubes, which are also excellent conductors of electricity
