Abstract
A matrix droplet extruder includes a casing; one or a plurality of reagent containers; a plurality of pneumatic connectors on the casing that are each configured to be connected to a pneumatic actuator to provide controlled pneumatic pressure to one or more of said plurality of the pneumatic connectors; a droplet matrix extrusion surface with one or a plurality of printing zones, each printing zone comprising an array of perforations; and a liquid management chip for dispensing one or more reagents from said one or a plurality of reagent containers through the array of perforations of said one or a plurality of printing zones, so as to repeatedly generate a matrix of droplets when applying the pneumatic pressure to said one or more reagents.
Claims22
1-8. (canceled)
A sample holder comprising:
- a casing with a pocket;
- a removable sample slide with one or a plurality of substrate patches configured to be inserted into or removed from the pocket;
- a sample channel for introducing a liquid sample into one or a plurality of sealed spaces between the sample slide and a section of the casing, so as to allow the sample liquid to be absorbed in said one or more substrate patches.
A sample analysis system comprising:
- a pneumatic actuator;
- one or a plurality of sample holders comprising:
- a casing with a pocket;
- liquid containers;
- a removable sample slide with a substrate comprising one or a plurality of substrate patches, configured to be inserted into or removed from the pocket;
- and
- a sample channel for introducing a liquid sample into one or a plurality of sealed spaces between the sample slide and a section of the casing, so as to allow the sample liquid to be absorbed in said one or more substrate patches;
- and
- a controller that is configured to control the pneumatic actuator so as to sequentially cause one or more liquids from one or more of the liquid containers to flow to or away from the sample slide in that sample holder;
- and
- an analysis module for examining the sample slide after contact of the sample with a plurality of dots of one or more reagents that are printed onto the substrate.
