摘要:The authors describe a voltammetric method for the determination of arsenite [As(III)] based on an As(III)-specific binding probe DNA (SBP DNA; a single-stranded DNA) and the electrochemical indicator Methylene Blue (MB). The SBP DNA was first hybridized with a capture probe...

摘要:Core-shell Au@Ag nanorods (Ag@GNRs) were synthesized and utilized to construct a voltammetric biosensor for trichloroacetic acid (TCA). The biosensor was prepared by immobilizing hemoglobin (Hb) on a glassy carbon electrode (GCE) that was modified with the Ag@GNRs. Cyclic vo...

摘要:The authors describe a molecularly imprinted polymer (MIP) deposited on multiwalled carbon nanotubes (MIP/MWCNTs) for separation and preconcentration of L-cysteine (L-Cys). The MIP was characterized by scanning electron microscopy, X-ray diffraction and FT-IR and via adsorpt...
