Functional Coating Layers in Biosensors, Microfluidic and Other Diagnostic Testing Kits
As growing industry of point-of-care, in-vitro diagnostic devices, need for precision coatings of active and non-active functional layers onto these devices is rapidly increasing.
Ultrasonic spray nozzles can spray onto targeted areas uniformly in ultra-low flow rate. Ultrasonic coating technology are highly controllable and repeatable, able to deposit precise thin films of solutions or suspensions such as biopolymers, proteins, EDTA, Heparin, amino acids, enzymes, blood plasma and preservatives.
