3D-Printed DNA “Glue” Could Lead to Bio-Engineered Tissues/Organs


In an article entitled “3D Printing with Nucleic Acid Adhesives” published in ACS Biomaterials Science & Engineering, researchers have successfully  demonstrated an inexpensive process that according to the ACS article creates ” DNA-coated nanoparticles made of either polystyrene or polyacrylamide. DNA binding adhered these inexpensive nanoparticles to each other, forming gel-like materials that they could extrude from a 3-D printer. The materials were easy to see and could be manipulated without a microscope. The DNA adhesive also allowed the researchers to control how these gels came together. They showed that human cells could grow in the gels, which is the first step toward the ultimate goal of using the materials as scaffolds for growing tissues.”  Read more at: http://www.acs.org/content/acs/en/pressroom/presspacs/2015/acs-presspac-january-14-2015/dna-smart-glue-could-someday-be-used-to-build-tissues-organs.html or the full article:
