Microinjectiuon device and microinjection method

摘要

A microinjection apparatus includes a substrate (12) having holes for trapping cells using suction force and injecting a substance into the cells with a needle. Height detection marks (13) are provided on the substrate (12). A visibility is calculated from an image of a height detection mark (13), and an amount of deformation of the substrate (12) is determined from the visibility. An XYZ table, on which the substrate (12) is placed, is moved based on the amount of deformation.
