      on slab optical waveguide with consecutive parallel Au and Ag deposition bands 
      coexistent with bisphenol A-immobilized Au nanoparticles.

AB  - A slab-type optical waveguide (s_OWG)-based microfluidic SPR measurement system 
      for bisphenol A was developed. This s_OWG possesses consecutive parallel gold and 
      silver deposition bands in the line of plasmon flow, allowing two individual SPR 
      signals to be independently obtained as a result of the difference in resonant 
      reflection spectra of these metals. As a molecular recognition element, 
      molecularly imprinted polymer nanoparticles (MIP-Np) were employed and 
      immobilized on the surface of each of the gold and silver deposition bands. The 
      resonant reflection spectra were measured on the MIP-Np-immobilized consecutive 
      parallel gold and silver deposition bands coexistent with BPA-AuNp. The Ag-based 
      SPR spectra showed a red shift (0.7 nm) when free BPA (0.1 mM) was passed over 
      the BPA-AuNp/immobilized MIP-Np complexes formed on the s_OWG, unlike the case 
      for the Au deposition band, while a large excess of BPA induced a blue shift due 
      to the competitive desorption of BPA-AuNp from the immobilized MIP-Np on the 
      s_OWG. By using the proposed detection system, binding events of other small 
      molecules could be monitored in conjunction with the use of MIP-Np and 
      labeled-AuNp.
