Mar. 9, 2006 – Dimatix, a provider of commercial and industrial ink jet products, announced that its researchers, in conjunction with several universities, have used its cartridge-based Dimatix Materials Printer (DMP) system to ink jet fluids containing fluorescently labeled proteins, enzyme mixes, genomic DNA, oligonucleotides, and living bacteria and yeast.

Through these experiments, the DMP, a system for high-precision jetting of functional fluids, has shown proven repeatability in printing aqueous, emulsion and solvent-based fluids.

“We’re making major advances in ink jetting biofluids through the work we’ve been doing with the DMP at several universities,” said Jan Sumerel, manager of biomedical sciences, in a prepared statement.

Dimatix’s DMP-2800 series printer can deposit 10 picoliter-sized droplets of fluid to print feature sizes as small as 40 microns on any type of surface, including plastic, glass, silicon, membranes, gels and paper. With the piezo ink jet deposition system, users can array biological fluids including buffers and reagents. Because of the unique single-use cartridge based system, the company says, cross contamination between samples is eliminated.
