RALEIGH – 3D-printable gels with improved and highly controlled properties can be created by merging micro- and nano-sized networks of the same materials harnessed from seaweed, according to new research from North Carolina State University. The findings could have applications in biomedical materials – think of biological scaffolds for growing cells – and soft robotics.
Described in the journal Nature Communications, the findings show that these water-based gels – called homocomposite hydrogels – are both strong and flexible. They are composed of alginates – chemical compounds found in seaweed and algae that are commonly used as thickening agents and in wound dressings.
Merging different-size scale networks of the same alginate together eliminates the fragility that can sometimes occur when differing materials are merged together in a hydrogel, says Orlin Velev, S. Frank and Doris Culberson Distinguished Professor of Chemical and Biomolecular Engineering at NC State and corresponding author of the paper.
