How does Arrayjet technology work?

For inkjet microarrays, aspiration is separate from deposition. Both take place within the same contained printing environment.

Sample Loading

Samples are loaded into the base of the printhead via a JetSpyder™ – Arrayjet’s patented aspiration device. As little as 0.5 µl of 12 or 32 samples can be aspirated at once – enough to print 2000 x 100 pL spots.

Aspirator detaches

After sample loading, the JetSpyder™ detaches from the printhead, which is cleaned and prepped for printing.

On-the-fly Inkjet Printing

The printhead glides across the substrates at 0.35 m/s, depositing sample without stopping or making contact. This is how we achieve our industry-leading speed.

How do Inkjet Microarrays compare?

Alternative approaches to printing microarrays include spotting with pins or dispensing via glass tips.

ARRAYJET’S INKJET GLASS TIPS PIN-SPOTTING
On-the-fly printing is up to 10x faster than glass tips, and 100x faster than pins. Stop-start sample deposition limits speed. Pin-spotting action for sample deposition is very slow.
Contactless deposition, compatible with a wide range of surfaces. Contactless deposition, compatible with a wide range of surfaces. Contact printing creates ‘donut’ shaped spots, invites cross contamination, and can damage print surfaces.
Inkjet printhead is highly robust, and also commercially available. Fragile glass tips break often and are expensive to replace. Pins are easily broken or bent and need replacing.
Print layout can be customised at the touch of a button. Print layout is limited. Print layout is fixed and requires a different set of pinheads for each array design.
Compatible with most biological samples, and optimal for printing small molecules. Compatible with many biological samples. Incompatible with higher-viscosity samples that can block pins.

COMBINATORIAL LIBRARY SCREENING

ArrayPlex™ Spot-On-Spot Microarrays

Arrayjet’s unique inkjet approach to bioprinting allowed us to develop ArrayPlex™ – our patented microarray platform. With ArrayPlex™ we can create multi-layered microarrays, allowing two libraries to be screened against each other. This takes throughput to the next level, generating millions of data points each week.

ArrayPlex™ is compatible with all sample types and detects hits at an equal or higher sensitivity to ELISA.
