Abstract

The analytical community continues to search for cost-effective, reliable, and even portable analytical techniques that can give reliable and fast-response results for a variety of biochemicals. Advances in the field of microelectro- mechanical systems (MEMS) and their uses now offer unique opportunities in the design of ultrasensitive analytical devices. Microcantilevers (MCLs) have been emerged as a novel unique platform for label-free biosensor or bioassay. This short review summarizes the biosensors using microcantilever (MCL) technology. DNA-based, antibody-based, enzyme- based, and membrane-based MCL sensors are discussed. The review is intended to provide an experts in this field an overview of MCL biosensors and to help the non-experts in the field to acquire a good understanding of the development of MCL biosensors and the main issues to be considered for further development of this biosensor technique.
