2. Description of the Related Art
A microscope cooperated with a slide glass or a cell counter is a traditional device for measuring cells and bio-specimen in basic biology, biomedical research, medical diagnostics and materials science. However, the mechanism of the microscope is usually complex and the equipment of it is hard to be carried. Moreover, a researcher should be received a professionally training to operate it, and it consumes long time to analyze measuring results.
For example, in order to measure dynamic sample of particles, e.g. spermatozoa, such as translation speed and the rotational speed of particles, the expert should place a drop of the sample in a cell counter, put the cell counter in the microscope, and manually count the number of cells in a certain area of the cell counter. Since the depth of the certain area is predefined, thus the volume of the counted cells can be calculated and the concentration of the counted cells can be obtained. The above-mention steps should be performed by the expert in a biological laboratory, therefore, that is quite inconvenient for human subjects.
Hence, there is a need for a portable device for measuring cells and bio-specimen that can improve sampling speed and simplify measuring process.
