Disclosed herein is a novel method to fabricate magnetic silica nanomembranes using thin polymer cores based on silica deposition and self-wrinkling induced by thermal shrinkage. These micro- and nano-scale structures have vastly enlarged the specific area of silica, thus the magnetic silica nanomembranes can be used for solid phase extraction of nucleic acids. The magnetic silica nanomembranes are suitable for nucleic acid purification and isolation and demonstrated better performance than commercial particles in terms of nucleic acid recovery yield and integrity. In addition, the magnetic silica nanomembranes may have high nucleic acid capacity due to significantly enlarged specific surface area of silica. Methods of use and devices comprising the magnetic silica nanomembranes are also provided herein.

Disclosed is a detection apparatus that transfers magnetic particles through a plurality of chambers in a cartridge which includes the plurality of chambers and a channel connecting between the plurality of chambers, and that causes the magnetic particles to carry a complex of a test substance and a labelling substance, to detect the test substance on the basis of the labelling substance in the complex. The detection apparatus includes: a rotation mechanism configured to rotate the cartridge about a rotation shaft; a magnet configured to collect the magnetic particles in the chambers; a movement mechanism configured to move the magnet in a direction different from a circumferential direction of a circle in which the rotation shaft is centered; a detector configured to detect the test substance; and a controller programmed to control the rotation mechanism and the movement mechanism so as to transfer the magnetic particles from one of the chambers to another one of the chambers.
