Traceable Impedance-Based Dispensing and Cloning of Living Single Cells

SLAS Technol. 2020 Jun;25(3):215-221. doi: 10.1177/2472630320905574. Epub 2020 Feb 18.

Abstract

Single-cell cloning is essential in stem cell biology, cancer research, and biotechnology. Regulatory agencies now require an indisputable proof of clonality that current technologies do not readily provide. Here, we report a one-step cloning method using an engineered pipet combined with an impedance-based sensing tip. This technology permits the efficient and traceable isolation of living cells, stem cells, and cancer stem cells that can be individually expanded in culture and transplanted.

Keywords: automated biology; engineering; microfluidics; microtechnology; systems.
