Abstract
(EN)
There are disclosed apparatus and methods for the field-assisted acceleration of biological processes involving charged entities, including in particular the detection of target DNA in a biological sample. A reaction cell is provided with a dielectric surface, and a field is generated by inducing charge-separation in the dielectric material by applying a potential to an electrode in contact with the dielectric material.

Se describen un aparato ymétodos para la aceleración asistida por un campo de procesos biológicos que involucran entidades cargadas, incluyendo en particular, la detección del ADN objetivo en una muestra biológica. Se proporciona una celda de reacción con una superficie dieléctrica y se genera un campo induciendo la separación por cargas en el material dieléctrico, aplicando un potencial a un electrodo en contacto con el material dieléctrico.
