Abstract

PURPOSE:To stably observe or measure a sample for a long time by closely adhering a cover glass having an observing specimen buried in an etching part to a slide glass with the specimen buried part being opposed. CONSTITUTION:A cover glass 2 etched to a prescribed depth is closely adhered to a slide glass 1 with a specimen 4 being buried in the etching part, and adhered by a sealing adhesive 3 to provide a microscopic sample. The covering pattern of a covering material is changed, whereby the etching can be formed as a groove of stripe, lattice, convex lens, or concave lens form. Further, when the specimen is changed by the oxygen or moisture in the air, a series of operation for micro-sample manufacture can be performed in a sealed vessel such as a glob box substituted with an inert gas such as nitrogen gas or argon gas.

2. Description of the Related Art Conventionally, in various fields such as microelectronics, biotechnology, and material science, for example, biological samples such as cells and DNA, minute samples such as metal samples, liquid samples, and emulsion samples, It is often necessary to observe and measure that area. Then, as one method for that purpose, observation and measurement using a microscope are performed.

In such observation and measurement using a microscope, it is necessary to prepare a sample to be the subject as a microscopic sample. Generally, when the sample is solid, the sample is placed on a slide glass. A method of mounting and placing a cover glass on it is adopted, and when a sample is a liquid, a method of putting a liquid sample on a hole slide glass and placing a cover glass on it is adopted.

However, in such a conventional method for preparing a microscopic sample, for example, a liquid sample is placed on a slide glass, electrodes are further mounted on the slide glass, and slide glass for surface treatment of the slide glass is used. Was extremely difficult to process. This is because the liquid sample spills from the slide crow during these operations and processing. Therefore, there is a limit in observing and measuring the electrochemical or photochemical properties of the sample under the microscope.

Further, for example, when handling a sample that changes due to oxygen or water in the air, since the sample may be altered during or after the preparation of the microscopic sample, the unstable sample in the air is stabilized. It was very difficult to make a storable microscopic sample. For example, if the sample has triplet excitons in the photochemical reaction, the triplet excitons are susceptible to triplet oxygen in the air, and the singlet oxygen generated at that time has a very high activity. Therefore, as a result, the specimen in the microscopic specimen may be altered.

As a means for preventing the photochemical reaction with respect to such a specimen, a method of removing air by passing an argon gas through an optical cell is generally used, and this method is applied to a method for preparing a microscopic sample. It was actually impossible to do because the sample is so small that volatilization and dissipation of the sample are unavoidable. The present invention has been made in view of the circumstances as described above, and it is possible to solve the drawbacks of the conventional microscopic sample and its manufacturing method and process the slide glass forming the microscopic sample. It is an object of the present invention to provide a new microscopic sample capable of stably observing and measuring a specimen for a long period of time without being affected by oxygen and water in the sample, and a method for producing the same.
