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) [...]

Microfluidics made by GeSiM: The Heart of a State-of-the-Art Water Monitoring System: Beside of bioinstruments, 25 years of experience in development of microfluidic flow-through-cells predestine GeSiM as a supplier of microfluidics for sophisticated miniaturized systems for pharmaceutical research, life sciences and biotechnology. The German Fraunhofer-IKTS Dresden is heading a publicly funded research project (BMBF project [...]

GeSiM now sells Bioinks: We are proud to launch the collaboration with the Korea based company InnoRegen, Inc., better known by their former name Bioink Solutions, Inc. InnoRegen develops and markets bioinks for 3D bioprinting, tissue engineering and 3D cell cultivation since several years. GeSiM is now sales partner, InnoRegen products are available from GeSiM [...]

Melt Deposition Modelling of Bioactive Organic/Inorganic Hybrid Scaffolds: Hybrid materials/ blends offer more potential to mimic artificial bones because of better biological/physical properties. E.g. cell adhesion might be much better than for pure PCL. 3D printing of such material, however, could be challenging due to difficult viscoelastic properties. A team at LPC lab (University of [...]

Peptide Chitosan/Dextran Core/Shell vascularized 3D Constructs for Wound Healing: Vascularization is still a challenge when creating artificial tissue by 3D printing. New Zealand researchers successfully put a step forward using the core/shell extruder of the GeSiM bioprinter BS3.1. This tool prints two different materials in a coaxial manner. The team at University of Otago used [...]

An Animal Study for Insulin Delivery by Microneedles: Microneedle arrays are miniature puncturing devices that disrupt the skin barrier to deliver therapeutic agents trans dermally, in a pain free manner. Common drawbacks associated with typical microneedle coating techniques such as dip-coating, suffer from poor controllability of the outcome in terms of coating morphology, spatial deposition [...]
