Researchers at the University of California Santa Barbara in the US have developed a new method of nanoscopic imaging for use in the early detection and diagnosis of multiple sclerosis and similar diseases.

Using nanoscoping imaging, researchers studied the myelin sheaths around the nerves of multiple sclerosis patients and observed differences in the appearance, size, and sensitivity to pressure of domains in the healthy and diseased monolayers.

The findings are expected to pave the way for new experimental methods for early detection, diagnosis, staging, and possible treatment of pathological tissues that are precursors to multiple sclerosis and other membrane-associated diseases.

University of California Santa Barbara chemical engineering and materials professor Jacob Israelachvili said defects in the molecular or structural organisation of myelin membranes lead to reduced transmission efficiency, which results in various sensory and motor disorders or disabilities, and neurological diseases such as multiple sclerosis.

Multiple sclerosis is characterised by the appearance of lesions or vacuoles in the myelin sheath, and eventually results in its complete disintegration.
