Abstract
he present invention relates to a microfluidic chip for attracting and destroying a specific biological element, said chip comprising:a reservoir (1) consisting of a matrix comprising a chemoattractant compound capable of attracting the biological elementat least one network of microchannels (2) arranged between the reservoir (1) and the external environment (3) of the chip and allowing the chemoattractant compound to pass to said environment and the biological element present in said environment to pass to the reservoir (1)at least one electrode (4) arranged between the reservoir (1) and the network of microchannels (2) or at the same location as the network of microchannels (2), said electrode (4) being capable of generating an electric field so as to destroy the biological element during its passage to the reservoir (1).
