Abstract:
Biological sensing technology has become a very active research field because it is a new interdiscipline about biology, chemistry, physics and information science and technology. Biosensor has been widely used in many areas such as medical science, pharmacy, environmental monitoring, defense and security after half a century of development. Printedelectronic technology is a frontier technology of the hybrid of modern printing technology and microelectronic technique, and is one of the best manners to fabricate biological sensors in industry scale. In this paper, the research progress of biosensor and its structure, type and sensing mechanism is introduced, the electrically conductive nano-materials, mediators, printing ink and action principle are summarized in different biosensors, the especially the application advantages and characteristics of screen printing, ink-jet printing, micro-contact printing and roll-to-roll printing in the preparation of biosensors.
