Bio-artificial tissue scaffold. Coloured scanning electron micrograph (SEM) of bio-artificial tissue created by 'printing' a viscous polymer mixture through fine inkjet nozzles. The technique, known as 'pressure assisted spinning' uses three inkjet needles nested inside one another to seperately deliver cells, a viscous polymer and pressurised air. This technique arranges cells more precisely than other bioprinter technologies. Bioprinters could one day build artificial tissues and organs for replacement organ surgery. Photographed in 2009 at the laboratory of Suwan Jayasinghe at the University College London, UK.
