摘要： The present invention concerns a device (1) for removing particles from a material in movement, wherein said particles comprise or are made of a substance that is attracted by a magnet. In a practical embodiment, the device (1) is used to remove iron particles from a stream of flour, for example flour produced in a mill and being dropped by way of gravity through the device (1) of the invention. The device (1) comprises a trapping arrangement (7) that is movably connected with respect to the device (1) in such a manner that a first trapping area (7a) is in a trapping position inside a channel (4) of the device (1) while a second trapping area (7b) is in a release position, releasing trapped particles. The trapping arrangement (7) then moves such that said second area (7b) gets into the trapping position and the first area (7a) to the release position. The device is self-cleaning and allows continuous removal of iron particles.

摘要： Provided herein are methods, systems, and devices for detecting and/or identifying one or more specific microorganisms in a culture sample. Indicator particles, such as surface enhanced Raman spectroscopy (SERS)-active nanoparticles, each having associated therewith one or more specific binding members having an affinity for the one or more microorganisms of interest, can form a complex with specific microorganisms in the culture sample. Further, agitating magnetic capture particles also having associated therewith one or more specific binding members having an affinity for the one or more microorganisms of interest can be used to capture the microorganism-indicator particle complex and concentrate the complex in a localized area of an assay vessel for subsequent detection and identification. The complex can be dispersed, pelleted, and redispersed so that the culture sample can be retested a number of times during incubation so as to allow for real-time monitoring of the culture sample.
