title: A label-free ultrasensitive electrochemical aptameric recognition system for protein assay based on hyperbranched rolling circle amplification.
abstract: A label-free ultrasensitive electrochemical aptameric sensor which combined the advantages of an aptamer and hyperbranched rolling circle amplification (HRCA) has been developed for specific recognition of a platelet-derived growth factor B-chain (PDGF-BB).
