With a global increased emphasis on biotechnology and alternative, biologically-based alternative fuel development, more and more analytical work is being done utilizing fluids that contain biological material. whether the work involves blood cell counting or bacteria culturing (among many other life science applications), one commonality is often the need to transfer biological samples from one point to another. sometimes this is accomplished through manual means (e.g., with manual pipetting); however, high throughput is also a major driver that continues to push the development of more automated techniques. The challenge many researchers face is how various pumping technologies negatively impact cellular…[Read this article]
Non-contact Dispensing Technology
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]
