Abstract:
This disclosure provides, among other things, a cartridge comprising: (a) a cartridge body comprising a malleable material and having, disposed on a surface of the body, at least one valve body comprising a valve inlet and a valve outlet, each fluidically connected to a fluidic channel; and (b) a layer comprising a deformable material bonded to a surface of the cartridge body and sealing the at least one valve body at points of attachment, thereby forming at least one valve; wherein the at least one valve body is depressed in the cartridge body relative to the points of attachment and wherein the deformable material covering the at least one valve body retains sufficient elasticity after deformation such that in a ground state the valve is open. Also disclosed is an instrument comprising a cartridge interface and a cartridge as described herein engaged with the cartridge interface.
Abstract:
Provided herein is a fluidic cartridge having a body comprising a malleable material and a layer comprising a deformable material bonded to a surface of the body that seals one or more fluidic channels that communicate with one or more valve bodies formed in a surface of the body. The valve can be closed by applying pressure to the deformable material sufficient to crush and close off a fluidic channel in the body. Also provided are a cartridge interface configured to engage the cartridge. Also provided is a system including a cartridge interface and methods of using the cartridge and system.
Abstract:
The present disclosure provides systems and methods for sample preparation, processing and analysis. Also provided in the present disclosure is a fully-integrated electrophoresis cartridge which has a small footprint and configured to removably engage with the system. An electrophoresis cartridge adapted to releasably engage with a cartridge interface of a system is provided. The electrophoresis cartridge comprises: an electrophoresis assembly including: (1) an anode sub-assembly comprising an anode, (2) a cathode sub-assembly comprising a cathode; and (3) at least one electrophoresis capillary having a first end and a second end, wherein the cathode and the anode are configured to provide a voltage gradient across the first end and the second end of the at least one electrophoresis capillary.
