Graphical Abstract
A coat to note: An electrochemical immunoassay strategy is developed using phospholipid-coated multiwalled carbon nanotubes (MWNTs) as the electrochemical labels (see scheme; PSA=antigen protein; MB=magnetic bead). This strategy affords great sensitivity and specificity in signal transduction.
