The present disclosure provides methods and systems for cell processing, including delivery of imaging agents into cells. The methods and systems may comprise the use of a microfluidic device. The microfluidic device may comprise a channel comprising a compressive element. The compressive element may be configured to reduce a volume of the cell and facilitate the formation of one or more transient pores in a cell membrane of the cell. The one or more pores may permit one or more imaging agents to enter the cell. Also provided are modified cells produced using the disclosed methods and systems and methods of imaging the modified cells in a subject.

Methods and systems for cell labeling and imaging

Described herein are methods and systems for mechanoporation-based high-throughput payload delivery into biological cells. For example, one system can process at least 1 billion cells per minute or at least 25 billion cells per minute, which is substantially greater than conventional methods. A cell processing apparatus comprises a processing assembly formed by stacking multiple processing components. Each processing component comprises channels, which may be used for filtration, mechanoporation, and/or separation of cells in the cell media. This functionality depends on the configuration of each channel. For example, each channel comprises one or more ridges such that each ridge forms a processing gap with an adjacent one of the processing components. The ridges may extend to the side walls or form a bypass gap with the wall. The processing gaps can be specially configured to compress cells as the cells pass through these gaps thereby initiating the mechanoporation process.
