New Bio-Ink Improves Cell Viability in Bioprinting
Researchers from the University of Wollongong (Australia) have advanced the realm of bioprinting with the development of a new improved bio-ink capable of printing living human cells into three-dimensional structures, according to a study published in the November issue of Biomaterials Science. The new bio-ink improves the viability of the cells. “To date, none of the available inks has been optimized in terms of both printability and cell suspending ability,” said Cameron Ferris, co-author and associate researcher at the Australian Research Council Centre of Excellence for Electromaterials Science, in a statement. “Our new bio-ink is printable and cell-friendly, preventing cell settling and allowing controlled deposition of cells.” The bio-ink is based on a biopolymer and two surfactants in a standard tissue culture medium. The ink was able to reproducibly print different cell types from commercial inkjet print heads, the researchers reported.
