Electrochemical investigation of DNA hybridization to ferrocene-labelled peptide nucleic acids on gold electrodes

摘要

@@ INTRODUCTIONGenetic testing is one of the foremost current topics in biochemical research,however,the traditionalmetho-ds for detecting DNA hybridization are too slow and labor intensive.Many different approaches have been proposed for genetic test[1] including DNA hybridiza-tion sensor,which,in particular,is one of the fastest growing arcas in genetic testing technology and has received increasing attentions for applications in clinical diagnostics,food quality control,and forensic science[2,3].
