Abstract

This paper presents the design and microfabrication of a vacuum-based cell holding device for single-cell immobilization and the use of the device in mouse zygote microinjection. The device contains many through-holes, constructed via two-sided glass wet etching and polydimethylsiloxane (PDMS)-glass bonding. Experimental results of mouse zygote immobilization and microinjection demonstrate that the device is effective for rapid cell immobilization and does not produce negative effect on embryonic development.
