Abstract
A fluidic device for performing assays can include control components such as vacuum pumps, gas pumps, 'broken open valves,' and 'self-close valves' for controlling the flow of fluids in the fluidic device. The vacuum pump can be used to pull a fluid in a specific direction in a channel, and the gas pump can be used to push a fluid in a specific direction in a channel. The broken open valve can be used to connect two separate regions at the control of a user, and the self-close valve can be used to automatically seal off a channel after passage of a fluid. The vacuum pumps, gas pumps, broken open valves, and self close valves can be made small in volume so that the fluidic device can be made as a small and portable device.
