Electrospinning is a technique that uses high voltage to deposit polymer nanofibers onto a surface from a liquid polymer solution. By using collection surfaces of various shapes and sizes as molds, this process can create standalone nanofibrous materials or coat nanofibers onto existing devices and materials.

​

The process begins with the selection of a biodegradable or non-degradable polymer, manufactured under GMP conditions or supported by an FDA master file. This polymer is dissolved into a specialized solvent system. When high voltage is applied, the solution forms a fine jet that accelerates toward the nearest grounded surface. As the solvent rapidly evaporates, a solid layer of polymer nanofibers—our proprietary Bio-Spun™ material—is deposited.

These nanofibrous materials offer unique microstructural and biological advantages compared to conventional woven or knitted materials commonly used in medical devices.

While this is a simplified overview, BioSurfaces’ Bio-Spun™ technology is the result of over two decades of dedicated research and development.
