Embodiment approach 1
[0048] The probe of the scanning probe microscope according to Embodiment 1 of the present invention is as figure 1 shown. Two or more monomolecular layers (1, 2, 3, 4, 5) are superimposed on the probe (1). In this specification, the term "monolayer" refers to a layer of specific molecules formed on an interface with a thickness of one molecule. Typical examples of monolayers include monomolecular films. Such as figure 1 As shown, the density of molecules contained in the stacked monolayers gradually decreases from the probe surface to the outer layer. As a result, the number of molecules contained in the outermost monolayer at the tip of the probe is limited to a minimum. Sensor molecules and catalyst molecules are used as molecules in the outermost monolayer on the probe (6), whereby in principle the chemical structure of individual molecules can be determined or processed. Meanwhile, when a molecule having a chemical sensor function or a catalytic function is used fo...
Embodiment approach 2
[0050] The probe of the scanning probe microscope according to Embodiment 2 of the present invention is as figure 2 shown. refer to figure 2 (A), forming an organic monolayer (20) on the surface of the probe (1). A monomolecular layer containing 100 or less molecules in a region (tip face) where the tip portion of the probe is in contact with the sample has a chemical sensor function or a catalytic function. Thus, in principle the chemical structure of single molecules in a sample can be determined or processed. In this specification, the terms "tip face" and "probe tip face" refer to the area of the probe where the tip portion of the probe comes into contact with the sample. Meanwhile, when a molecule having a chemical sensor function or a catalytic function is used in the outermost monolayer, the same function can be imparted to the probe. Furthermore, if the molecules are covalently linked between the probe and the monolayer thereon, and between individual monolayer...
Embodiment approach 3
[0053] The probe of the scanning probe microscope according to Embodiment 3 of the present invention is as image 3 shown. refer to image 3 (A), the probe of Embodiment 3 is characterized in that the surface of the probe is covered with a conductive polymer (30), and a catalyst (31) selected from inorganic and organic catalysts is contained in the polymer. image 3 (B) shows that at least one organic molecular film (32) is formed on the coating layer containing the conductive polymer (30), and there are molecules with chemical sensor function or catalytic function on the outermost organic molecular film on the tip surface of the probe instance of . exist image 3 In the example shown in (B), the functional molecule (33) is connected to the organic molecular film (32). Since the catalyst (31) contained in the conductive polymer and the functional molecule (33) on the outermost organic molecular film on the tip face of the probe have different functions, by a single process...
