Investigation and Development of Functionalized Aptamer-based Biosensor
Due to the high sensitivity and selectivity,excellent stability and wide application areas,aptamer- based biosensors have been quickly developed in recent years. Various aptamer biosensors have been designed according to different principles. In the present paper, we have mainly reviewed the development of electrochemical,fluorescent and colorimetric aptamer sensors. The potential development about aptamer-based biosensors has been discussed.
