Background

The specimen slice is a common teaching aid for biological course teaching, is used for packaging a biological specimen on a flaky glass plate and presents the microscopic form of a specific tissue through microscopic observation. At present, for biological materials such as chromosomes and peripheral blood cells, a high-power microscope is needed for observation, and in order to overcome the problem that the object is not clear due to refraction of light when a high-power mirror is used, a cedar oil film is often needed to be constructed between a lens and a specimen slice.

After the specimen slice is used, the cedar oil is usually cleaned by adopting dimethylbenzene or ethanol and diethyl ether, then is washed clean by using a large amount of water, and then is dried in the air, so that the specimen slice can be repeatedly used. In the above-mentioned washing and drying processes, moisture or organic solvents easily intrude into the interior of the form sheet, and contaminate the biological material. In addition, the conventional specimen sheets are thin and smooth in surface, and thus are not easy to stably hold.
