French startup develops polymer liquid to aid nerve healing

A French startup has created a biodegradable material designed to improve recovery from nerve injuries. The thick, sticky liquid is already being used by surgeons in the United States.

Roughly 500,000 Americans require treatment each year for nerve damage. Common causes include accidents in the kitchen or workshop, and many patients never regain full sensation in affected areas such as the fingers.

The company has developed special polymers that form the basis of the new material. It is described as a thick and sticky liquid that supports healing after surgery.

Deployment of the product with American surgeons has begun, according to the report.

Duke University researchers report that boosting the transfer of healthy mitochondria from support cells to sensory neurons reduced pain-like behaviors in mouse models of diabetic and chemotherapy-related peripheral neuropathy, an approach they say could address a root driver of nerve pain rather than simply blocking pain signals.

Researchers at Drexel University have discovered that certain viscous liquids can snap apart like solids when stretched with sufficient force. The finding, detailed in a study published in Physical Review Letters, challenges traditional views of fluid dynamics by linking the behavior to viscosity rather than elasticity. This phenomenon was observed in simple liquids such as tar-like hydrocarbons and styrene oligomer.
