Abstract
A microfluidic flow cell for removably interfacing with a removable-member for performing a reaction therebetween. The microfluidic flow cell device comprises at least one reaction portion defining with the removable-member a reaction chamber when in an interfaced position thereof. The microfluidic flow cell comprises at least one fluid-receiving portion for receiving a fluid therein and being in fluid communication with the reaction chamber. When the microfluidic flow cell and the removable-member are in the interfaced position, the cell is adapted to allow for the fluid in the fluid-receiving portion to flow to the reaction chamber. Devices, systems and methods comprising this microfluidic flow cell are also disclosed.
Claims143
A microfluidic flow cell for removably interfacing with a removable-member for performing a reaction therebetween, said microfluidic flow cell comprising:
- at least one reaction portion defining with the removable-member a reaction chamber when said microfluidic flow cell and said removable-member are in an interfaced position thereof;
- and
- at least one fluid-receiving portion for receiving a fluid therein and being in fluid communication with said reaction chamber;
- wherein when in said interfaced position, said microfluidic flow cell is adapted to allow for the fluid in said fluid-receiving portion to flow to said reaction chamber.
A microfluidic device comprising:
- a microfluidic flow cell in combination with a removable-member;
- at least one reaction chamber defined by said microfluidic flow cell and said removable-member when in an interfaced position thereof for performing a reaction therein;
- and
- at least one fluid-receiving chamber for receiving a fluid therein and being in fluid communication with said reaction chamber;
- wherein said microfluidic flow device is adapted to allow for the fluid in said fluid-receiving chamber to flow to said reaction chamber.
A microfluidic device according to 61, wherein said fluid is initially in dry form and is adapted to be liquefied.
A microfluidic system for driving fluids, said system comprising:
- at least one microfluidic device comprising:
- a microfluidic flow cell comprising at least one reaction portion and at least one fluid-receiving portion for receiving a fluid therein;
- a removable-member for interfacing with said microfluidic flow cell as to perform a reaction therebetween;
- a reaction chamber for performing a reaction therein, said reaction chamber being defined by said reaction portion when interfaced with said removable-member, said reaction chamber being in fluid communication with said fluid-receiving portion;
- and
- a force-providing device for providing an external force onto said microfluidic device so as to provide for the fluid in said fluid-receiving portion to flow to said reaction chamber.
A method for driving fluids used in a reaction within a microfluidic structure, said method comprising:
- (a) providing a microfluidic structure comprising a microfluidic flow network interfaced with a removable-member for defining a reaction chamber therebetween, said reaction chamber being in fluid communication with said network;
- (b) placing at least one sample fluid product within said network and at least one reacting product in one of said network and said reaction chamber;
- (c) actuating the microfluidic flow network so that products in said network are driven to said reaction chamber for providing a reaction therein;
- and
- (d) removing at least a part of said removable-member from said network with a result of the reaction being provided on at least one of said removable-member and said network.
