Printed Electronics with GeSiM Bioprinters: GeSiM bioprinters offer qualitative advantages over the competition. Two important points: The variety of different extrusion tools allows to print a huge range of polymers, more than just biocompatible materials. The high XYZ accuracy – particularly with BS5.x instruments – allows to print at higher resolution then many other bioprinters [...]
Drug Release of Antibiotics through 2-phase 3D-printed Hydrogel Structures: Anti-inflammatory antibiotics are crucial for the treatment of open fractures and large, open wounds. Several ways to administer such medication are known, but the controlled local application at the wound area is often difficult. A team from University Hospital Dresden now published a new approach, using [...]
Bioengineering, Ordering Up Organs: Radio New Zealand (RNZ, “Our Changing World”) interviews the users of a GeSiM BioScaffold printer BS3.1 at University of Otago. It belongs to the core instruments for Dr. Jaydee Cabral, a research fellow at the Chemical Department. She uses the unit successfully since 2017, working on different projects. Beside of biomaterials [...]
3D Printing of Multi-layer Scaffolds to mimic Patient Specific Implants: Customers at University Hospital of TU Dresden conducted a research study for the future therapy of osteochondral defects. They developed a workflow, based on a magnetic resonance imaging (MRI) dataset derived from a real clinical case. MRI provides more information on cartilage tissue and muscles, [...]
Array-based Chemical Synthesis: DNA- and protein microarrays are available for many years, nowadays widely used for modern in-vitro diagnostics. They are based on prefabricated biomolecules, tethered on solid surfaces by special surface chemistry (E.g. Amino-silane slides). When the spotted arrays are exposed to the analyte, just one specific reaction can happen on each spot with [...]
We are proud to present a new sales partner in Europe: The company Bio-Science Kft. will support the GeSiM marketing, sales and service activities for the bioprinters in Hungary. Bio-Science – a traditional Hungarian company – sells laboratory equipment to customers in the fields of life science, chemistry and pharmacy. The company is headquartered in [...]
Fluidautomation at your Fingertip: Hard- and software for automated fluid handling are available in many variations these days. If complexity, flexibility and speed are paramount in your F/E tasks, you should take a look at the new MicCell-FluidProcessor from GeSiM. Complex procedures, comprising single steps like pumping, mixing, dispensing, measurements and temperature control, are easy [...]
One Step towards Artifical Liver Models: The sophisticated tools of the GeSiM bioprinters enable high-level tissue engineering. Here we present a recent paper published by the Centre for Translational Bone, Joint and Soft Tissue Research at the Faculty of Medicine of TU Dresden. The liver is a pretty complex organ, consisting of different cell types [...]
PDMS Spotarrays with the Microarray Printer Nano-PlotterTM: Polydimethylsiloxane (PDMS) is a widely used silicone elastomer with interesting properties such as low cost, biocompatibility and optical transparency. Cost-effective prototypes of flow-through cells are popular in microfluidics. PDMS has a cross-platform meaning for the GeSiM product portfolio: Our microcontact printers do fine and precise surface reliefs featuring [...]
Melt Electro Writing Scaffolds seeded with Stem Cells: Melt Electro Writing (MEW) allows to create much smaller pores compared to syringe powered extrusion. Smaller pores are supposed to offer better conditions for cell proliferation. Our customers at University of Otago, Dunedin, NZ, used thin (3…4 layers) MEW scaffolds from PCL 50,000. Mesenchymal stem cells (T0523) [...]
