The integrated nanoliter system consists of microfabricated fluidic channels, heaters, temperature sensors, and fluorescence detectors. The microfabricated fluidic channels (basically very small pipes) act as the main transportation structures for any fluids as well as where reactions occur within the system.
Due to the extremely low amounts of liquids 0.1 - 10 nl and reagents, the methods to work with nanoliterplates are completely different compared to the methods used for microliter plates. Nanoliter plates reduce the amount of reagents, require lower sample volumes and increase the numbers of tests that can be performed in the lab.
Droplet Digital PCR (ddPCR) is a method of dPCR in which a 20 microliter sample reaction including assay primers and either Taqman probes or an intercalating dye, is divided into ~20,000 nanoliter-sized oil droplets through a water-oil emulsion technique, thermocycled to endpoint in a 96-well PCR plate, and fluorescence amplitude read for all ...
This is necessary since the signal-to-noise ratio of sample sizes in the microliter to nanoliter range is dramatically reduced compared to bench-scale sample sizes, and microcoils have been shown to resolve this issue. [84] Mass spectrometry (MS) and high-performance liquid chromatography (HPLC) have also been used to overcome this challenge.

The term nanoprobe also refers more generically to any chemical or biological technique that deals with nanoquantitles, that is, introducing or extracting substances measured in nanoliters or nanograms rather than microliters or micrograms. For example:
