Solving for Substrate and Reagent Interactions On Biosensor Surfaces Coating the surface of a Biosensor with biologically active matrices is commonplace. The level of difficulty increases when you need to accomplish this with low microliter or sub-microliter volumes. Further complications arise when you need to have the matrix uniformly dispersed over a customized sensor shape without breaching boundaries. In short, this is no easy task! One of the greatest advantages of low-volume, non-contact dispensing is that the dispensing needle does not come into contact with the substrate–so dispensing quality is independent of substrate. As non-contact dispensing moves into more non-standard…[Read this article]
