Magnetically-controlled micro-fluid system for e.g. 'lab-on-chip' system for determination of presence of bio-molecules, virus, biological cells
A micro-fluid system transports tiny particulate quantities of a biological or pharmaceutical liquid sample through a channel exposed to the effect of a magnetic force generated nearby. The channel is exposed to two or more magnetic sources, each separated from the other. - The magnetic force is generated by an electro-magnet by a spiral micro-coil. The coil longitudinal axis runs along or is transverse to the micro-channel. The coil has a core whose tip is directed at the micro-channel. The magnetic fields intersect at predetermined points in the channel. Each channel is in close parallel proximity to a second channel. The channels merge and the fluids combine under the effect of the magnetic sources. The magnetic field forces are variable and regulated.
