  • Publication number: 20230400392
    Abstract: The present disclosure provides a method of cell sedimentation and retention of target cells, for example circulating tumour cells, CTC, from a fluid sample onto a solid support. The method comprises placing a fluid medium comprising the target cells in a fluid chamber, the fluid chamber having an open end sealed against a surface of the solid support. The method further comprises subjecting the fluid medium to centrifugation within the fluid chamber to induce sedimentation of the target cells and promote cell adhesion to the surface of the solid support. The method further comprises, post-centrifugation, positioning a fluid absorbing element in the fluid chamber to remove fluid from the fluid chamber. The method further comprises controlling a flow rate of the fluid being absorbed by the fluid absorbing element such that the sedimented cells are not detached from the surface of the solid support.

  • Patent number: 11604119
    Abstract: The present disclosure provides a cell harvesting method and device for the efficient sedimentation and retention of cells from liquid samples onto a solid support with low cell losses and low impact on cell morphology. The device has two configurations, one being for use in a centrifuge to centrifuge the sample, a second for controlled release of the liquid post centrifugation. The device includes a base to hold a solid support that receives cells on a top surface thereof that releasably holds a fluid chamber which has a first opening with a gasket surrounding the opening with that bears against a top surface of the support. An opening receives the liquid sample and the gasket defines an area into which the targeted cells deposit. A first cap closes the second opening during centrifugation.

  • Patent number: 9989525
    Abstract: The present disclosure provides a diffraction based biosensor containing at least two diffraction gratings. The first grating is referred to as an in-coupling diffraction grating and the coherent light source (laser) is directed to illuminate the in-coupling grating, and the biosensor is configured such that a selected order of the light beam diffracted from the in-coupling diffraction grating illuminates a second biosensor grating coated with analyte-specific receptors which are selected to preferentially bind with analytes being tested for that may or may not be located in a sample being tested.
