Abstract :

A multiple metal layer coated microfluidic channel has been prepared by a metal evaporating method for a miniaturized biosensor chip. Microfluidic sensor chips such as biochips, lab-on-a-chips and diagnostic chips are rapidly developed for medical, biochemical, and nano bio-technological applications. An electrode metal material such as Pt or Au was generally coated on a part of a microfluidic channel of a biosensor. However, a thin metal layer could be used as a reflective surface of an incident light in a microfluidic sensor chip that has a spectroscopic detector to analyze a biochemical material in a sample solution. Thus, a metal layer, Pt or Al/Pt, was coated on the whole surface of a microfluidic channel including bottom and top surfaces by metal evaporating procedures. Especially, Al was coated on the surface of a microfluidic chip to reflect UV light including visible light. Then, Pt was coated on the Al layer of the microfluidic chip to provide a chemically inert surface. The prepared metal coated microfluidic channels were characterized by optical and electrical microscopic methods and a spectroscopic method.
