TI  - Immobilization of Pt Nanoparticles via Rapid and Reusable Electropolymerization 
      of Dopamine on TiO(2) Nanotube Arrays for Reversible SERS Substrates and 
      Nonenzymatic Glucose Sensors.

AB  - Inspired by mussel-adhesion phenomena in nature, polydopamine (PDA) coatings are 
      a promising route to multifunctional platforms for decorating various materials. 
      The typical self-polymerization process of dopamine is time-consuming and the 
      coatings of PDA are not reusable. Herein, a reusable and time-saving strategy for 
      the electrochemical polymerization of dopamine (EPD) is reported. The PDA layer 
      is deposited on vertically aligned TiO(2) nanotube arrays (NTAs). Owing to the 
      abundant catechol and amine groups in the PDA layer, uniform Pt nanoparticles 
      (NPs) are deposited onto the TiO(2) NTAs and can effectively prevent the 
      recombination of electron-hole pairs generated from photo-electrocatalysis and 
      transfer the captured electrons to participate in the photo-electrocatalytic 
      reaction process. Compared with pristine TiO(2) NTAs, the as-prepared Pt@TiO(2) 
      NTA composites exhibit surface-enhanced Raman scattering sensitivity for 
      detecting rhodamine 6G and display excellent UV-assisted self-cleaning ability, 
      and also show promise as a nonenzymatic glucose biosensor. Furthermore, the 
      mussel-inspired electropolymerization strategy and the fast EPD-reduced 
      nanoparticle decorating process presented herein can be readily extended to 
      various functional substrates, such as conductive glass, metallic oxides, and 
      semiconductors. It is the adaptation of the established PDA system for a 
      selective, robust, and generalizable sensing system that is the emphasis of this 
      work.
