摘要

Method and apparatus for selecting the desired cells or parts of cells, distribution device of a sperm cell.Method for selecting a desired viable sperm cell suitable for in vivo or in vitro and viable sperm cell of the invention refers to a method that uses the orientation of aA sperm cell to determine the differences of the cell due to the size, mass, or density.The differences of cells, such as differences in the mass of DNA, are used to distinguish the sperm cells that contain X chromosome of sperm cell containing Y chromosome.Therefore, have use in procedures of in vitro and in vivo. The orientation of individual sperm cells is determined by measuring the fluorescent light.The method uses a detector to measure the magnitude of fluorescence (for the measurement of DNA (sex) of the flat surface of the spermatozoon).And a second detector to measure the magnitude of the fluorescent light petrographic derived from a light source separately.The light source is derived from part of a separate optical system by phase contrast or dark field to provide the data for guidance.It is important to note that all the excitement and the fluorescent light is excluded from the second detection system for optical filters of the passage.Thereby obtaining a clearer signal of the edge cu00f3ncava (no sign of the fluorescence of the flat surfaces of the spermatozoon).It is reported that the orientation of a sperm cell.When determined by the passage of light by using the optical sistma phase contrast or dark field through a sperm cell of interest, provides greater efficiencies.Higher processing speeds and greater reliability in the results obtained.An additional aspect of the invention describes a laser immobilization or ablative for restraining or destroy unwanted sperm.
