Lab-on-a-Chip uProcess™ Application: Continuous Dispensing

Particularly in biological experiments, it is necessary to deliver fluid at flow rates of ≤ 1μl/min over experiment times of hours to days.  As a result, a relatively large total volume is dispensed to the experiment, sometimes as much as 1-10 ml. In lab-on-a-chip experiments, a small overall experimental platform is often desired. This creates the challenge of … Read more

Lab-on-a-Chip Application: Circulating Tumor Cell Immuncapture Automation

The manipulation of biological samples for diagnostic purposes requires reproducibility and simplicity to be useful in practice. As microfluidic devices transition towards use in medical diagnostics, traditional handheld syringe pumps can be too bulky and laborious for medical procedures that require quick turnaround times. Here, we discuss the evaluation of a portable breadboard platform that … Read more

Hydrodynamic Focusing using Integrated Modular Pumps, Valves, Connectors & Imaging

Hydrodynamic focusing capitalizes on the inherent advantages of the flow physics of a microfluidic system to overcome functional challenges encountered in microfluidic conditions such as mixing and the delivery of particles such as cells for counting.
