Abstract: The present disclosure relates to optical crosstalk reduction in particle processing (e.g., cytometry including flow cytometry using microfluidic based sorters, drop formation based sorters, and/or cell purification) systems and methods in order to improve performance. More particularly, the present disclosure relates to assemblies, systems and methods for minimizing optical crosstalk during the analyzing, sorting, and/or processing (e.g., purifying, measuring, isolating, detecting, monitoring and/or enriching) of particles (e.g., cells, microscopic particles, etc.). The exemplary systems and methods for crosstalk reduction in particle processing systems (e.g., cell purification systems) may be particularly useful in the area of cellular medicine or the like. The systems and methods may be modular and used singly or in combination to optimize cell purification based on the crosstalk environment and specific requirements of the operator and/or system.

Abstract: A microfluidic chip having a micro channel for processing a sample is provided. The micro channel may focus the sample by using focusing fluid and a core stream forming geometry. The core stream forming geometry may include a lateral fluid focusing component and one or more vertical fluid focusing components. A microfluidic chip may include a plurality micro channels operating in parallel on a microfluidic chip.

Abstract: The present disclosure provides improved particle processing (e.g., cytometry and/or cell purification) systems and methods that can operate in an autonomous fashion. More particularly, the present disclosure provides for assemblies, systems and methods for analyzing, sorting, and/or processing (e.g., purifying, measuring, isolating, detecting and/or enriching) particles (e.g., cells, microscopic particles, etc.) where human intervention is not required and/or is minimized. The systems, assemblies and methods of the present disclosure advantageously improve run performance of particle processing systems (e.g., cell purification systems, cytometers) by significantly reducing and/or substantially eliminating the burden of operation for human intervention by automating numerous functions, features and/or steps of the disclosed systems and methods.
