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.
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.
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.
Paper-based microfluidics are considered as portable point-of-care biosensors used in a remote setting where advanced medical diagnostic tools are not accessible. [51] Current applications include portable glucose detection [ 52 ] and environmental testing, [ 53 ] with hopes of reaching areas that lack advanced medical diagnostic tools.
The tips are plastic-made tools for single-use. In general, they are made of Polypropylene. Depending on the size of the pipette, the user needs specific tip sizes like: 10 μL, 100 μL, 200 μL, 1,000 μL, other non-standard sizes, such as 5,000 μL (5 mL) or 10,000 μL (10 mL).
Magnetic droplets, in the context of droplet-based microfluidics, are microliter size droplets that are either composed of ferrofluids or contain some magnetic component that allows for manipulation via an applied magnetic field. Ferrofluids are homogenous mixtures of colloidal solutions of magnetic nanoparticles in a liquid carrier. [80]
Schematic diagram of one particular realization of nanofluidics in a nanocapillary array membrane, or NCAM. The NCAM is composed of a large number of parallel nanocapillaries, each of which have a pore radius, a/2, which is approximately the same size as the Debye length, κ −1.
