Microelectromagnetic dispenser heads and uses thereof

Abstract

This invention relates generally to the field of moiety or molecule transfer. In particular, the invention provides a microelectromagnetic dispenser head, which head comprises: a core comprising a magnetizable substance, said core surrounded by a microcoil suitable for transmitting electrical current and generating a magnetic field via said magnetizable substance and said core having a tip suitable for attracting a magnetic or magnetically labeled moiety; and preferably further comprising one or both of the following: i) a shell that substantially shields magnetic field, generated via said microcoil, from the non-tip portion of said core; and/or ii) a cooling means for cooling said tip. Microelectromagnetic dispensers comprising the heads and methods for transferring moieties using the heads and the microelectromagnetic dispensers are also provided.
