Embodiment

[0025] Electrochemical atomic force microscope probe holder--electrolytic cell device, the electrolytic cell 1" is made of polytetrafluoroethylene material, the shape is round or square, the outer diameter is 30.20mm, the inner diameter is 20.28mm, and the height is 5.40mm. Replace the perspective window of the AFM probe frame with ordinary quartz glass and use ITO transparent conductive glass (indium tin oxide transparent conductive film) with a thickness of 0.4mm, a length of 18.0mm, and a width of 9.0mm as the counter electrode 5", using a transparent conductive Glass as the perspective window of the atomic force microscope has little effect on the laser adjustment and detection of the atomic force microscope. A silver wire with a diameter of 0.4mm is fixed on the side of the electrolytic cell 1" as the reference electrode 2", and an ITO transparent conductive glass with a thickness of 0.4mm, a length of 9.0mm, and a width of 9.0mm is used as the working electrode 3". The c...

Abstract

The invention discloses an electrochemical atomic force microscope probe carriage-electrolytic cell device and belongs to the field of scanning probe microtechnique. Common glass is replaced with transparent conductive glass for a window of an atomic force microscope probe carriage, the transparent conductive glass is used as a counter electrode, the counter electrode is parallel to an operating electrode, the counter electrode is larger than the operating electrode in area, the problem of nonuniform electric field distribution is solved, and layout and installation of the electrodes in the electrolytic cell are simplified. Using the transparent conductive glass as the window of the atomic force microscope is nearly impervious to laser adjustment and detection of the atomic force microscope.

Description

technical field [0001] The invention relates to scanning probe microscopic imaging technology, in particular to an electrochemical atomic force microscope probe frame-electrolytic cell device, which belongs to the field of scanning probe microscopic technology. Background technique [0002] In 1986, Binning, Quate and Gerber invented the first atomic force microscope (Atomic Force Microscope, AFM), which can not only operate under vacuum and atmospheric conditions, but also work in a solution environment, and has nanometer to atomic resolution. For most biological samples, the solution environment is closest to its natural physiological state, and its biological activity can be maintained in a liquid environment; many chemical reactions also need to be carried out in a liquid environment. Therefore, the atomic force microscope working in solution environment has important practical application value and broad application prospect. [0003] Electrochemistry-Atomic Force Micr...
