1. A method of storing microfluidic samples, the method comprising:
- providing a chip having an array of sample wells for storing microfluidic samples; and
providing a fluid access structure to a selected subset of sample wells from the array of sample wells, the fluid access structure comprising one or more openings defining a fluid access region;
wherein the selected subset is less in number than the number of sample wells in the array;
providing a fluid introduction mechanism and introducing a sample fluid to the fluid access region by dragging-the sample fluid across a selected subset of sample wells with the fluid introduction mechanism so that the sample wells in the selected subset are populated with the sample fluid without the unselected sample wells being populated with the sample fluid, wherein the fluid introduction mechanism overlays at least two sample wells of the subset of the sample wells.

Abstract
An interface is provided for storing microfluidic samples in a nanoliter sample chip. A fluid access structure provides a fluid access region to a selected subset of sample wells from an array of sample wells. A fluid introduction mechanism introduces a sample fluid to the fluid access region so that the sample wells in the selected subset are populated with the sample fluid without the unselected sample wells being populated with the sample fluid.
