Abstract:
Microfluidic microchip for the chemical, physical, and/or biological analysis or synthesis of substances, with a channel structure, wherein the substances are capable of moving, in accordance with the channel structure, under the imposition of an electrical potential, comprisinga channel structure with at least one leading channel connected in a substance conductive manner to at least one delivery channel for delivering the substances, and at least one discharge channel for discharging the substances at least two points of intersection, whereby between the point of intersection of the delivery channel and the leading channel on the one hand, and the point of intersection of the discharge channel and the delivery channel on the other, at least one leading channel section of predetermined length is formed; a first activation source coupled to the areas of the delivery channel and the discharge channel for forming a potential for providing the substantially continuous movement of the substances from the delivery channel via the leading channel to the discharge channel; at least a second activation source, coupled to the area of the leading channel section, for forming a pseudo-random modulated signal for causing pseudo-random modulated movement of the substances located in the leading channel section for forming separated substance volume units corresponding to the modulated signal.
