DNA Nano Device Sequencer

A multidisciplinary team of Brigham Young University scientists has developed a way to significantly reduce cell death when introducing DNA into egg cells. The researchers have created a microscopic lance that delivers DNA to the cells through electrical forces.

“Because DNA is naturally negatively charged, it is attracted to the outside of the lance using positive voltage,” said Brian Jensen, BYU professor of mechanical engineering. “Once we insert the lance into a cell, we simply reverse the polarity of the electrical force and the lance releases the DNA.”
