Biosensors of in vitro detection of cancer and bacterial cells

This chapter describes some representative examples of in vitro detection of cancer and bacterial cells within the scope of biosensor systems. In cancer cell detection, priority is given to aptamers-based biosensors and the detailed information about the detection of cancer cells with the help of aptamers is explained. In the case of bacterial cells detection, electrochemical and optical biosensors that produce an electronic or optical signal proportional to the specific interaction between the target and the recognition molecule immobilized on the biosensor is elaborately exampled. In addition, microfluidics, LOC and paper-based detection systems for in vitro bacterial cells detection are emphasized in the chapter. © The Institution of Engineering and Technology 2016
