ElectroPen: An ultralow-cost piezoelectric electroporator

Electroporation is a powerful alternative to heat shock for delivering small molecules such as plasmids across cell membranes.  By application of an electrical field netivetly charged DNA is forced into elector-competent cells by an electrohoresis-type effect. Electroporators can be expensive, generally over $2000, hence the popularity of more chemical solutions such as heat shock. Enter […]
