Lab-on-a-chip devices often require one or more reagents to provide accurate test results. These reagents can be added either as a liquid during the assay or pre-loaded on the device in a dried format. This dried format will then be reconstituted during the assay, thus reducing handling steps for the end-user and ensuring a longer shelf life for the product.
Micronit offers the ability to deposit picolitre spots with high accuracy on your desired substrate using an in-house automated piezo actuated non-contact dispensing system. This technology is ideal for depositing reagents or spotting microarrays on microscope slides, biosensors, membranes, microfluidic devices and many other substrates. Varying droplet volumes allow for transferring common assays into a microfluidic format, thereby reducing the amount of costly sample and reagents required as well as the assay turnaround time. It is possible to accurately deposit the reagents in your desired array on basically any substrate type. Furthermore, the ability to control humidity and temperature allow for controlled drying of reagents for consistent functional results.
Our experts have experience in spotting various reagents including proteins (i.e. enzymes, antibodies), nucleic acids (i.e. oligonucleotides), buffers, nano particles (i.e. beads), sugars and surfactants that allow us to support the development, integration and/or miniaturisation of your assay to a microfluidic format.
