PROBLEM
Surgical mesh is used to prevent bacteria and carry oxygen, especially for surgical wound sites. Current mesh technologies are often expensive, however, and can lead to long-term post-surgical complications such as adverse bodily response to a foreign object.
SOLUTION
Purdue researchers have introduced a new solvent-free, cost-efficient, scalable process for making strong, flexible, biodegradable surgical mesh. This approach has been tested with various compositions of calcium peroxide on polymer fibers to develop a mesh with excellent oxygen permeability.

ABSTRACT
Resorbable Surgical Mesh Impregnated with Calcium Peroxide

Researchers at Purdue University have developed a new resorbable surgical mesh that is impregnated with calcium peroxide for regeneration of tissue at dermal wound sites. Surgical mesh is used to prevent bacteria and carry oxygen, especially for surgical wound sites however, current mesh technologies are often expensive and can lead to long-term post-surgical complications such as adverse bodily response to a foreign object. Purdue researchers introduce a new solvent-free, cost-efficient, scalable process for making strong, flexible, biodegradable surgical mesh. This approach has been tested with various compositions of calcium peroxide on polymer fibers to develop a mesh with optimal porosity, verified by scanning electron microscopy (SEM), which allows for excellent oxygen permeability. The new mesh was cultured with HMS-32 skin cells in vitro, exhibiting 90-92% cell viability as well as having ability to prevent necrosis by reducing hypoxia-induced cell death within six days.
