    摘要: The present invention includes an article of manufacture or device, or related system, comprising a heterogeneous surface for selective analyte sensing or separation. Such an article can comprise a surface member and a plurality of spaced components extending therefrom and coupled thereto, such a surface member and spaced components providing a surface heterogeneity selected from different electrostatic interactions, different non-electrostatic interactions and a combination of such interactions, such that the interactions are at least partially sufficient for selective analyte interaction and/or separation. Each such component extension can be of a nanometer dimension about the Debye length of a medium comprising an analyte particle exposed to such a surface. An analyte particle, optionally of a mixture of particles, can be dimensioned from about 30 nm to 20 μm. In some embodiments, the extended components have a density at least partially sufficient for interaction of a single such component or multiple components with a single analyte particle, at a given Debye length. In other embodiments, such components have an average spatial density at least partially sufficient for selective particle interaction and/or separation.

    摘要: Textured heterogeneous surfaces and related articles as can be used in conjunction with methods for selective sensing and/or separation. When used for selective particle separation such a system can comprise a heterogeneous surface comprising a surface member and a plurality of components extending therefrom, such components spaced about and having a surface density, with heterogeneity comprising different interactions of the surface member and of the extended components with a particle exposed thereto. Various surface heterogeneities and different interactions can be utilized. However, in certain embodiments, competing electrostatic interactions, or a combination of electrostatic and non-electrostatic interactions, with a particle can be utilized. Such a system can utilize a surface member having a charge difference with respect to the components extending therefrom.

    摘要: Poly(anilineboronic acid)/phosphate nanoparticle dispersions are produced in high yields using the reactivity of the boronic acid moiety with phosphate in the presence of fluoride. The poly(anilineboronic acid)/phosphate dispersions have been characterized using spectroscopic, microscopic and electrochemical techniques. According to 11B NMR studies, the formation of anionic tetrahedral boronate group in phosphoric acid in the presence of fluoride forms the basis of self-doped, stabilized PABA nanoparticle dispersion. Transmission electron microscope images show that 25-50 nm diameter PABA nanoparticles are formed under these conditions. UV-vis, FT-IR-ATR spectroscopic and cyclic voltammetric results confirm the formation of the conducting form of PABA. Films produced from these particles exhibit enhanced redox stability and potential dependant conductivity under neutral and basic pH conditions due to the formation of a boron-phosphate complex containing fluoride, which results in a self-doped form of the polymer.
