SYSTEM AND METHOD FOR DEFORMING AND ANALYZING PARTICLES
A system for deforming a plurality of particles carried in a sample volume includes a reusable substrate defining an inlet, configured to receive the sample volume, and an outlet, wherein the inlet or outlet is configured to couple to a module to introduce or collect a washing or flushing solution. A fluidic pathway is disposed in the reusable substrate and fluidically couples to the inlet and the outlet and includes a delivery region fluidically coupled to the inlet and configured to focus the plurality of particles along at least one streamline and a deformation region located downstream with respect to the delivery region and formed by an intersection of the fluidic pathway and an opposing inlet channel, wherein flow of a fluid from the opposing inlet channel at the intersection mechanically deforms the plurality of particles passing through the deformation region.
1 . A system for deforming a plurality of particles carried in a sample volume, the system comprising:
a reusable substrate defining an inlet, configured to receive the sample volume, and an outlet, wherein the inlet or outlet is configured to couple to a module to introduce or collect a washing or a flushing solution;
a fluidic pathway disposed in the reusable substrate and fluidically coupled to the inlet and the outlet and comprising:
a delivery region fluidically coupled to the inlet and configured to focus the plurality of particles along at least one streamline; and
a deformation region located downstream with respect to the delivery region and formed by an intersection of the fluidic pathway and an opposing inlet channel, wherein flow of a fluid from the opposing inlet channel at the intersection mechanically deforms the plurality of particles passing through the deformation region.
2 . The system of claim 1 , wherein the reusable substrate is configured for washing and reuse.
3 . The system of claim 2 , wherein the reusable substrate is self-washing.
4 . The system of claim 1 , wherein the reusable substrate is reusable for a plurality of uses and is configured to be replaceable.
5 . The system of claim 4 , wherein the reusable substrate comprises aligners that align the reusable substrate relative to a detection module configured to capture a morphology dataset comprising multiple positions and/or deformations of the plurality of particles upstream and downstream of the deformation region.
6 . The system of claim 4 , wherein the system is configured to be reusable for a certain number of uses.
7 . The system of claim 4 , wherein the system is configured it be reusable until failure by clogging.
8 . A method of using the system of claim 1 , comprising:
introducing a first sample volume into the inlet and mechanically deforming the plurality of particles therein;
introducing the washing or the flushing solution into the inlet or outlet from the module;
introducing one or more additional sample volumes into the inlet and mechanically deforming the plurality of particles therein, wherein the washing or the flushing solution is introduced into the inlet or outlet from the module prior to the one or more additional sample volumes being introduced into the inlet.
9 . The method of claim 8 comprising replacing the reusable substrate with another reusable substrate and introducing another sample volume into the inlet and mechanically deforming the plurality of particles therein.
