Multiplex tests and microarrays give the ability to detect many protein or DNA markers in one assay. In addition, since the assay results are obtained under the same conditions, a good ranking can be had. Furthermore, an added benefit is to use a minimal amount of precious sample. While there are several approaches to multiplexing, planar arrays offer an established platform that is amenable to a wide range of tests.
At axiVEND, we focus on multiplex tests and microarrays development and production by providing solutions used to create and read microarrays of all types. These can be printed on semiconductors, glass slides, and various plastic surfaces, such as microtiter plates. The arrays are typically used to achieve multiplexed testing for diagnostics applications, allergy testing, genetic identification, ... Examples include oligo arrays, antigen arrays, antibody arrays, small molecule arrays. They are used to look at protein profiles, gene expression, and to detect biomarkers or other analytes.
Spotters used for the creation of microarrays are also used for the ultra-low volume liquid deposition of materials into various structures. A prime example is the deposition of reagent into Microfluidics chips during their manufacturing. Pre-loading reagents into Microfluidics can help in creating minimally instrumented chips. These are in turn well suited for point-of-care / point-of-use devices.
Beyond biologicals, chemical reagents can be spotted onto electrochemical sensors to enable sensor chip manufacturing for environmental testing, such as for monitoring air and water quality, food supply safety, and biodefense.
