Extraction of materials from regions of interest in a sample
First Claim
1. A method of extracting material from a region of interest, comprising:
- aligning one or more fluid channels of a fluid delivery base with an alignment member to define a region of interest on a sample, wherein the fluid delivery base and the alignment member are positioned on opposing surfaces of the sample such that the fluid delivery base and the alignment member are separated from one another by at least the sample and wherein the aligning comprises moving the fluid delivery base into a magnetic field of the alignment member, or moving a magnetic field of the fluid delivery base towards the alignment member;
delivering extraction fluid to the sample via the one or more fluid channels; and
collecting the extraction fluid via the one or more fluid channels.

Abstract
A system for extracting material from a region of interest includes a fluid delivery base comprising an inlet channel and an outlet channel formed within the fluid delivery base, a gasket affixed to the fluid delivery base, wherein the gasket comprises at least one opening exposing an open end of the inlet channel and an open end of the outlet channel; a support comprising a sample-supporting surface facing the gasket and an opposing surface; and an alignment member coupled to the opposing surface in a fixed position and such that the support is positioned between the fluid delivery base and the alignment member, wherein one or both of the alignment member or the fluid delivery base are biased towards one another by a force (e.g., a magnet or spring force) and wherein the fluid delivery base is separable from the support and configured to move along a plane of the sample-supporting surface to align with the alignment member.

18. A system for extracting a material from a region of interest of a sample, comprising:
-
a fluid delivery base comprising a fluid inlet channel and a fluid outlet channel fluidically coupled to the fluid inlet channel, the fluid inlet channel arranged to deliver an extraction fluid to an isolated portion of the sample corresponds to the region of interest, for extracting the material from the region of interest, and the fluid outlet channel arranged to collect the extraction fluid and the material extracted from the same region of interest; a gasket affixed to a sample-facing surface of the fluid delivery base, the gasket configured to isolate the region of interest upon direct contact with the sample; a support comprising a sample-supporting surface configured to hold the sample against the gasket and an opposing surface; and an alignment member coupled to the opposing surface such that the support is positioned between the fluid delivery base and the alignment member, wherein the fluid delivery base is separable from the support and configured to align with the alignment member under magnetic force.
