Electrochemical and Electrochemiluminescent Aptasensors

Aptamers have been widely used for the detection of target molecules owing to their chemical stability, easy modification and remarkable specificity and affinity for various target molecules. Electrochemical methods are well known for low cost, high sensitivity and usage of miniature instruments. Recently, the design of electrochemical aptasensors has attracted significant attention in the field of biosensors. This paper mainly reviews the developments of these aptasensors since 2005, and discusses the prospects.
