Perhaps a peristaltic pump[1], with the rollers spaced appropriately to achieve the minimum incremental amount?

To handle liquids on that volume range, biologists use micropipettes. These can be operated by a robot: https://www.youtube.com/watch?v=3ouPBX65kXU

Most large-scale projects already involve automated liquid handling such as Tecan EVOs and Beckman Coulter BioMeks - these have been around for years.
I have an idea for a hobby project that involves building a robot to mix small amounts of (safe, non-biological) liquids... need to be able to dispense 0.1ml to 10ml range, but very precisely.
My current thinking is hooking up syringes with one way valves (one going to the supply, one going to the output) ... and a linear actuator or screw drive to move the plunger back and forth-- so on the pull stroke the syringe would fill from the reservoir and on the push stroke it would fill the output.
But I figure there might be an off the shelf solution for something like this that's hacker friendly.
