Artificial skin from agricultural waste

Artificial skin from agricultural waste

Bacterial nanocellulose has a number of advantages over its plant analogue, regular cellulose. Its fibers are longer, wider and stronger. Such pulp has practically no impurities that would impair its strength and absorbing properties.

Russian scientists developed a new method of obtaining a nutrient medium for the synthesis of bacterial nanocellulose. As a source of raw materials, they used oat husks and miscanthus biomass. Researchers used chemical accelerating enzymes to turn raw materials into sugar solutions to produce nanocelluloses.

Bacterial nanocellulose could be instrumental in creating of artificial skin: it plays an active role in stimulating regenerative processes, helping to heal wounds. Due to the large surface area and porous structure, nanocellulose is able to absorb a significant amount of various substances that can be used in medicine to create bandages. The high strength of bacterial nanocellulose makes it possible to use it as a material for 3D printing of certain types of human tissue, for example, cartilage.
