Our Service for Your Microarrays
Pre-sales feasibility tests with your materials, tailored instruments and after-sales service will take you to success. Please contact us for further details…
Manufacturing of Array Based Diagnostics
Manufacturing of state-of-the-art diagnostic kits requires more precise liquid handling than ever before. The Nano-Plotter is your solution to address these needs. The instrument covers the volume range from Picolitre to Microlitre, well appropriated for but not limited to the classical microarray format. The flexible software prints lines on Nitrocellulose membranes and applies Nanolitre volumes to microfluidic cartridges…
Arraying into 96-Well Plates
Micro titer plate based assays allow multi-parameter analysis with arraye of capture molecules bound to the well bottom. Today commercial plates in the 96-well SBS format support reproducible tethering of proteins and other biomolecules to the plate bottom…
No Crosscontaminations with Larger Sample Sets
The effective tip cleaning system of the Nano-Plotter avoids carry-over when processing larger sets of samples. The GeSiM Nano-Plotter keeps each sample species separated from the next one very precisely. Here we provide basic information…
Reverse Phase Protein Arrays (RPPA)
A simple, robust and highly parallel assay architecture for monitoring of protein expression and activation. Our microarray printers are perfect to do lysed-cell arrays…
Glycoprotein Arrays
Complementary to the popular antibody arrays, this application uses pre-separated proteins from cellular lysates or other biofluids. This work was conducted by the Lubman Research Laboratory, University of Michigan, Ann Arbor (USA)…
Loading of Biosensors
Label free detection of biomolecules is an attractive solution for users, but challenges liquid handling technology. Small but exact sample aliquots need to be tethered onto tiny areas of electronic chips. No problem for the Nano-Plotter camera system. Read how electrical biochips are manufactured at Campton Diagnostics…

Heatable piezoelectric dispensers enable micro dosage of Nanolitre volumes of high-viscous adhesives…
Collision of Droplets
The high kinetic energy of flying microdroplets supports mixing of mixable liquids when pre-dispensing mixing is not feasible…
Fibronectin Patterns Printed with µCP
Fibronectin coating is popular to enforce cell adhesion to surfaces. Microcontact printing allows partial and well-defined preparation of surfaces. Here HUCB-NSC were grown on microcontact printed fibronectin squares…
Micro Needle Arrays by NIL
High-aspect-ratio 3D objects like micro needles are feasible with the GeSiM micro-contact-printers. Micro needle arrays are a popular research field for alternative subcutaneous drug delivery…
Nanoplasmonic Sensor Structure by NIL
The performance of label-free SPR detection can be improved by nano-structured surfaces made by NIL (Nano-Imprint Lithography). This customer project focuses on the design of a waste-water sensor…
Picolitre Wells for Cell Biology
NIL with UV-curable adhesives allows the design of Picolitre wells to attract single cells per well…

What are GeSiM bioprinters used for…?
Melt Deposition Modelling of Bioactive Organic/Inorganic Hybrid Scaffolds
Bioactive hybrid materials, e.g. blends of PCL/glass show a great potential to mimic artificial bones. However, Additive Manufacturing (AM) with these materials could be challenging due to difficult physical properties, e.g. viscoelasticity. A team at the LPC (University of Clermont, France) is using the GeSiM HT-extruder on a BioScaffold printer BS3.2 successfully and printed such formulations for the first time accordingly to CAD models…
Melt Electro Writing of Milk Protein/PCL Blends for Skin Regeneration
The influence of milk proteins on the properties of PCL was investigated by the Department of Chemistry at the University of Otago, New Zealand. Special focus was put on the usage of the Melt Electro Writing unit of the GeSiM BioScaffold printer BS 3.1. The used milk proteins, Lactoferrin and Whey Protein, are supposed to increase the biological functionality of PCL…
Melt Electro Writing Scaffolds seeded with Stem Cells
Another project at the University of Otago investigates the influence of scaffold pore sizes on growth and proliferation of mesenchymal stem cells. The cells were placed in a “sandwich” structure, consisting of different pieces of very thin PCL scaffolds made by Melt Electro Writing (MEW). A new method was developed for monitoring cell proliferation inside of opaque scaffold structures…
PCL-PEG Blends for Tissue Engineering
A customer at Friedrich-Alexander University Erlangen (FAU) succeeded in improving the properties of PCL for tissue engineering by adding PEG. These biopolymers shall be optimized towards a quicker degradation/mass loss when getting in contact with body fluid…
Struts and Capsules
A group from the FAU Erlangen added prefabricated capsules enriched with cells to hydrogels before printing. Different components desirable for bone regeneration, e.g., cells and bioactive proteins, can be incorporated both in the capsules and struts. This enables compartmentalization of components, which facilitates greater flexibility in modification of the scaffold…
Green Bioprinting
A team from the Technische Universität Dresden printed algae cells suspended in hydrogel together with mammalian cells. The cocultivation of algae in close vicinity to human cells could enable a sustained delivery of oxygen or secondary metabolites with therapeutic potential to human cells without the need of external supply. The fabrication of patterned coculture scaffolds can be easily realized by two-channel plotting…
Alginate/Methylcellulose Blends
Immediate cross linking of Alginate after printing can be avoided – Accordingly to an approach of researchers at the Technische Universität Dresden. The addition of Methylcellulose (MC) to low concentrated alginate leads to an enhanced viscosity and therefore improved printing conditions…
Bioprinting: The Future of Surgery?
In a joint research project with the Technische Universität Dresden a scaffold model of a human scaphoid bone was printed from Calcium Phosphate Cement. The STL data of the scaphoid bone were achieved by segmentation of DICOM data resutling from a CT Scan…
As FAST as Possible
An EU funded Consortium (Horizon 2020) was setup to optimize bulk and surface properties of scaffold materials for implants. GeSiM has been engaged for the development of high-performance syringe extruders for printing of polymer gradients through a single tool and within one layer. Further GeSiM adapted the NADIR plasma pen to the the BioScaffold printer BS5.1; now it can be used with all other GeSiM bioprinter tools…
