According to an article in Biotech Business Week dated October 30, 2006 , Spire Corporation (SPIR) was awarded a two-year grant by NIH-NIAMS to develop a new coating for orthopedic implants using nanomaterials. The new technology is supposed to greatly reduce wear and tear on the implants caused joint articulation in the human body.
