We automated removal of the swine oocyte zona pellucida using a 2DOF magnetically driven microtool (MMT) on a microfluidic chip. Multiple oocytes can be manipulated simultaneously highly stably, providing strong advantages over conventional manual manipulation using pipetting. We propose automating this process by activating a soft polymer microtool on a disposable microfluidic chip to stably mass-produce peeled oocytes – a breakthrough in high throughput and effective oocyte manipulation in cloning and fertility treatment.
