Abstract
Methods and devices for testing a biological sample are provided. A tape includes multiple channels or reservoirs having inlet and outlet ports. One tape having biological sample disposed in its channels is temporarily mated with another tape having reagents disposed in its channels via a serpentine belt and compression roller assembly. Pulsed fluidic operations combine the reagents and the biological sample for subsequent observation, detection, storage and/or disposal. Fluidic transfer is provided in a uniform operation or in conjunction with a sensory feedback assembly.
Claims25
A method for testing a biological sample, the method comprising:
- providing a first tape comprising a plurality of channels, each channel having one or more channel ports;
- disposing the sample into a first channel;
- providing a second tape comprising a plurality of inlet/outlet ports;
- engaging the first tape with the second tape to align a first inlet/outlet port with a first channel port of the first channel;
- introducing a reagent into the first channel through the first inlet/outlet port and the aligned first channel port;
- and
- withdrawing a portion of the reagent from the first channel via a second channel port aligned with a second inlet/outlet port.
