Researchers at Tufts University develop bio ink that withstand being processed by inkjet printers.
Utilizing a silk-based ink, researchers at Tufts University at Medford, Mass, have developed a more heat resistive bio-ink that can be printed on inkjet printers.
Bio-inks have, in the past, been used to be drawn directly onto human skin et al to help monitor such medical concerns as glucose levels, but the fact that the inks are highly heat sensitive has meant it is impracticable to be produced on a wider scale via inkjet printers.
But now, thanks to the Tufts team, it has created a silk-based ink that contains bacteria-sensing agents that can produced on such printers, meaning a wider application of biomolecules.
