That’s right. printing atomic force microscope images. The AFM image above is of a hydrogel, a network of polymers that’s mostly water, but has a huge number of crosslinked polymers.
The newly developed hydrogel precursor comprises alginate (natural polysaccharide derived from brown algae), RGD peptide-containing mussel adhesive protein, calcium ions, phosphonodiols ...
Graphene and carboxyl-functionalized multiwalled carbon nanotubes (C-MWCNTs) were composited and integrated into a double-network hydrogel composed of sodium alginate (SA) and polyacrylic acid (PAA) ...
