Engineers from Nanyang Technological University in Singapore have found a new material for 3D bioprinting, it
First, the researchers made from solid particlespollen microgel and mixed it with hyaluronic acid and biocollagen. Then they printed a bioscaffold from the resulting bioink - this is a three-dimensional polymer that is implanted into the body and helps with cell restoration.
Collagen was then added to the bioscaffold tocreate reference points for human tissue cells. As a result, the researchers found that the bioscaffold is 96-97% effective: it is filled with cells that then reproduce and continue to form biological tissue.
The authors note that only materials made from inverted colloidal crystalline hydrogels have such efficiency: their creation requires much more time and effort.
The authors believe the pollen microgel could be used to create a new class of environmentally friendly 3D printing materials.
