3-D Photografting Grows Bio Tissue

Facebook X LinkedIn Email
VIENNA, Aug. 27, 2012 — Photografting, a new form of three-dimensional printing that uses lasers to precisely attach molecules at specific places in a material, could soon make it possible to grow biological tissue or to create microsensors. Many ways exist to create 3-D objects on the micrometer scale. But tuning chemical properties of materials at micrometer precision is extremely complicated. The new method was devised by two Vienna University of Technology teams led by professors Jürgen Stampfl and Robert Liska, both of whom have received considerable attention for previous work with 3-D...Read full article

    hydrogel
    A hydrogel is a three-dimensional network of polymer chains that are hydrophilic, meaning they have a strong affinity for water. This network structure allows hydrogels to absorb and retain large amounts of water while maintaining their structural integrity. Hydrogels are often soft and flexible, resembling natural tissues, which makes them useful in various biomedical, pharmaceutical, and engineering applications. Hydrogels can be synthesized from natural or synthetic polymers. Natural...

    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
