Finding Early Signs of Arthritis

Atomic-force microscopy could advance osteoarthritis drug development.
Osteoarthritis, which affects about 14 million people in the United States alone, occurs when cartilage between joints degrades and disappears, leaving joint bones to grind painfully against each other. Therapies can alleviate some of the pain, and some patients undergo joint replacements, but there is no cure. Now nanotechnologists at the University of Basel, in Switzerland, have demonstrated that the molecular changes characteristic of the disease’s earliest stages can be detected using an atomic-force microscope (AFM). The researchers hope that using the extremely sensitive technique to monitor response to osteoarthritis therapies will speed the development of more-effective drugs for the disease.
