Disclosed herein include systems, apparatuses, devices, and methods for introducing one or more components into a fluid. A first fluid and a second fluid can be co-injected into a fluidic channel of a flow cell. In some embodiments, the first fluid and a second fluid are immiscible (e.g. an aqueous buffer and a non-aqueous liquid). In some embodiments, the second fluid is less dense than the first fluid.

Precise delivery of components into fluids

Microfluidic devices are described that include a microfluidic channel, a first array of one or more magnets above the microfluidic channel, each magnet in the first array having a magnetic pole orientation opposite to a magnetic pole orientation of an adjacent magnet in the first array, and a second array of one or more magnets beneath the microfluidic channel, each magnet in the second array having a magnetic pole orientation opposite to a magnetic pole orientation of an adjacent magnet in the second array. The first array is aligned with respect to the second array such that magnetic fields emitted by the first array and second array generate a magnetic flux gradient profile extending through the channel. An absolute value of the profile includes a first maximum and a second maximum that bound a local minimum. The local minimum is located within the microfluidic channel or less than 5 mm away from a wall of the microfluidic channel. Methods of using the new devices are also described.

Microfluidic sorting using high gradient magnetic fields

Disclosed herein are methods, devices, and systems for loading and retrieval of particles. In some embodiments, a loading station comprise a tray configured to receive a microwell array, a first magnet, a second magnet, and an actuation mechanism configured to cause movement of at least one of the first magnet and the second magnet.

Loading station

Disclosed herein are methods, devices, and systems for efficient loading and retrieval of particles. In some embodiments, a fluidic channel of a flowcell comprises a ceiling, a first sidewall, and a bottom, wherein the contact angle of the ceiling is at least 10 degrees smaller than the contact angle of the first sidewall, and wherein the bottom of the fluidic channel comprises a substrate that comprises a plurality of microwells.

Hydrophilic coating of fluidic channels

Disclosed herein are methods, devices, and systems for fluidic handling. In some embodiments, a gasket for providing a fluidic interface with a flowcell includes an inner cavity extending distally from a proximal end of the gasket, the inner cavity being defined by a plurality of inner surfaces sections, an inlet port positioned at a distal end of the inner cavity, an outlet port positioned at a distal end of the gasket, and a cannula extending between the inlet port and the outlet port; wherein at least some of the plurality of inner surface sections are tapered towards the distal end of the gasket to direct a pipette tip received within the gasket towards the inlet port of the gasket.
