Sandwich separation is based on forming a sandwich complex with a magnetic bead, buoyant bead, and a target. Once a sandwich formation is created, the sandwich can be separated using its dual physical properties, namely magnetism and buoyancy. Sandwich separation is highly specific, allows for removal of the beads that do not have any attached target, and reduces the number of background beads. Sandwich separation can also be used to allow for target detection in raw specimen. Also, improvement of detection capability is accomplished by performing AMBR measurements on a solid interface, where the rotational period speeds up and allows for dramatically reduced time-to-result.

A system for buoyant separation includes a separation container. Additionally or alternatively, the system can include an automated instrument, one or more processing components, and/or any other components. A method for buoyant separation can include any or all of: manipulating the separation container; adding materials to the separation container; removing materials form the separation container; otherwise processing the separation container; and/or any other processes.

A method and system for buoyant separation of a target constituent of a sample, the method comprising: at a process chamber, combining a volume of substrates having a first density with the sample, thereby producing a population of target-bound complexes comprising the target constituent bound to at least a portion of the volume of substrates; within the process chamber, physically separating the population of target-bound complexes from the sample based upon interaction between the volume of substrates and an applied force; aggregating the population of target-bound complexes at a collection region of the process chamber; extracting the population of target-bound complexes from the process chamber; and processing the target constituent from the population of target-bound complexes for further analysis.

A system for partially or fully automated, buoyancy-assisted separation includes and/or interfaces with an automated instrument.

Identification, quantification and characterization of biological micro- and nano-systems is enabled by magnetically spinning these natural, non-magnetic systems with the aid of induced magnetization. Biofriendly magnetic micro- and nano-labels enable magnetorotation in extremely weak electromagnetic fields. The spinning of these micromotors can be observed by a simple, CD-like, optical tracking system. The spinning frequency response enables real-time monitoring of single (cancer) cell morphology, with sub-microscopic resolution, yielding previously undeterminable information. Likewise, it enables super-low detection limits for any (cancer) biomarker.

The present invention relates to biological sensors. In particular, the present invention relates to the use of remotely driven nonlinear rotation of particles (e.g., magnetic particles) for detection of cells such as microorganisms (e.g., bacteria and viruses). The present invention further relates to the use of remotely driven nonlinear rotation of particles for measurement of physical properties of a solution (e.g., viscosity).
