Abstract: A device for extracting nucleic acids includes a cover including a first opening and a second opening spaced apart from the first opening, a chip including a first terminal to communicate with the first opening and a second terminal to communicate with the second opening, and a flow channel of the chip including an inner surface onto which immobilized beads are dispersed for binding with nucleic acids in a fluid flowing in the flow channel.

Abstract: Within each of a microfluidic mixer apparatus and a microfluidic reactor apparatus, as well as respective methods for operation thereof, there is provided a substrate having formed therein an aperture. Within the microfluidic mixer apparatus and its method of operation there is introduced into the aperture at least a pair of reagents through a pair of channels which terminate obliquely at the aperture, such as to provide a swirling mixing of the pair of reagents. Within the microfluidic reactor apparatus, the aperture comprises a first end portion contiguous with a middle portion in turn contiguous with a second end portion, where the middle portion, but not the first end portion or the second end portion, has at least one baffle intruding therein.
