Active Biochip Technology

Biochip technology is a novel technology that has received much attention around the world in recent years Biochips are essentially miniaturized analytical devices for biochemistry It can be divided into two categories: passive biochips and active biochips With features of rapidity,highefficiency and automation due to application of physical forces or fields for chip construction and assay,the active biochip is potentially a basic element for labonachip to realize the integration of bioassay processes,and it has become the most important field of biochip research In this article,typical active biochips are introduced Their principles,applications and progresses in development are described in detail
