摘要：
A microfibrillar cellulose substrate having a defined morphology and optimized concentrations of free radicals formed by milling a source material containing alpha cellulose with non-metalic cutting surfaces into a sterilized fine powder with a particle size of approximately 20 to 35 micrometers. A gauze selected from the group consisting of a woven, nonwoven, and extruded netting substrate for supporting the microfibrillar cellulose substrate. The microfibrillar cellulose substrate may be carried between a first layer of the gauze and a second layer of the gauze by affixing the first and second gauze layers closed around their perimeter.
