Abstract: The present disclosure relates to a probe capable of electrochemical and Raman spectroscopic monitoring wherein a Raman-active gold microshell having conductivity is attached to the tip of a glass microcapillary tube in which a conductive material is coated on an inner wall thereof by electroless plating. By coupling the probe with a system capable of moving the probe, the activities of various catalyst materials can be detected quickly and information of intermediate products moving from and adsorbed on the surface can be provided.

Abstract: A method for the fabrication of a mesoporous metal electrode in a non-liquid crystalline phase was tested. Specifically, there was tested the efficacy of the method for the fabrication of a mesoporous metal electrode which comprises forming the mesoporous metal electrode on a substrate by chemical or electrochemical reduction of a mixture comprising a solvent, a structure-directing agent, and a source of a metal, characterized in that the mixture is maintained in a non-liquid crystal phase. Furthermore, the usefulness of the mesoporous metal electrode thus prepared from the non-liquid crystalline phase was also tested. The mesoporous metal electrode prepared from the non-liquid crystalline phase had a large surface area, and a roughness factor thereof was controlled by charges passed during electroplating. The method made it possible to fabricate the mesoporous metal electrode in the non-liquid crystalline phase, even more flexible than a liquid crystalline phase.

Abstract: The present invention relates to a mesoporous platinum electrode for detecting biochemical substrate, comprising an electrode and a mesoporous platinum layer covering the surface thereof, and a method for detecting a biochemical substrate using the mesoporous platinum electrode. Using the present invention, glucose concentration can be selectively determined while excluding interference of interfering agents.

Abstract: The present invention relates to the microsphere whose surface is covered with hot spots and the method for identifying chemicals through Surface Enhanced Raman Scattering (SERS) using the same. The microsphere having hot spots, according to the present invention, includes a microsphere and metal networks as a shell which covers the surface of the microsphere, and nano-sized pores are distributed randomly on the surface or in the interstitial space of the metal networks. The microsphere having hot spots, according to the present invention, can be individually manipulated under a conventional optical microscope. SERS spectra of the monolayer of molecules on Pt or Au can be measured using single microsphere having hot spots mentioned as a sensitive probe. The microsphere having hot spots can be applied for decoding the microspheres with Raman tags flowing in a microfluidic system.

Abstract: The present invention relates to a microchip using polyelectrolyte salt bridge for cytometry, velocimetry, and cell sorting. The microchip comprises; a) an inlet for solution to be analyzed, b) a microchannel which provides a moving passage for solution to be analyzed, c) at least one outlet for solution to be analyzed which has passed through the moving passage, d) at least one electrode system comprising a first and a second salt bridges connected to the microchannel (the two salt bridges face each other), and a first and a second reservoirs connected to said each salt bridge (the reservoir comprises electrode and standard electrolyte solution). The microchip detects analytes in the solution to be analyzed (for example, a cell) by detecting change of impedance. In detail, anion in the standard electrolyte solution, which is comprised in the first reservoir, moves from the first salt bridge to the second salt bridge across the microchannel.
