20200284696 · 2020-09-10 ·

A collection device for collecting a sample dissected or ablated from an object includes a collection container configured to collect the dissected or ablated sample. An electrode pair is arranged on a side of a base of the collection container facing away from the object or on or in the base itself. The electrodes of the electrode pair are arranged concentrically. A voltage supply is configured to apply a voltage to the electrodes of the electrode pair such that a divergent electric field is generated at least in a region of the collection container.

Compositions and methods for laser capture microdissection

Compositions and methods for the simulataneous capture and release using micropattern surfaces for tissue and cell microdissection. In one example, a patterned thermoplastic film has a first surface and a plurality of projections attached to and extending outwardly from the first surface. The projections form a pattern on the thermoplastic film.

Method for laser microdissection, laser microdissection system and computer program

A method for laser microdissection includes: processing a microscopic examination object by a laser beam using tuples of coordinate values which respectively indicate positions of target points on the examination object at least in a first spatial direction and a second spatial direction orthogonal to the first spatial direction, positions of at least three reference points being ascertained beforehand in each case in the first and second spatial directions and also in a third spatial direction orthogonal to the first and second spatial directions; defining a reference plane based on the positions of the reference points; and determining, for the target points, further coordinate values indicating an expected position of the target points on the examination object in the third spatial direction in each case, as determined further coordinate values, the determining of the further coordinate values being performed depending on the defined reference plane.

Systems, methods and components for isolating cells from a fluid sample

A system for isolating preselected cell types from a fluid sample that includes a plurality of cell types includes a cell-capture fluidic chip, and a chip holder configured to receive the cell-capture fluidic chip and to maintain the cell-capture fluidic chip with a substantially fluid-tight seal while in operation. The chip holder is further configured to release the cell-capture fluidic chip to be removed from the chip holder for further processing. The cell-capture fluidic chip includes a substrate, a laser micro-dissection membrane disposed on the substrate, and a channel-defining layer disposed on the laser micro-dissection membrane. The laser micro-dissection membrane has a surface adapted to capture preselected cell types preferentially over other cell types of the plurality of cell types. The channel-defining layer is removable from the laser micro-dissection membrane for further processing of the cell-capture fluidic chip.
