Microfluidic flows need only be constrained by geometrical length scale – the modalities and methods used to achieve such a geometrical constraint are highly dependent on the targeted application. [10] Traditionally, microfluidic flows have been generated inside closed channels with the channel cross section being in the order of 10 μm x 10 μm.
Since microfluidics enables experiments with small volumes (including analysis of single cells or few cells), Raman is a leading microfluidic detection method. Specifically, Raman integration with microfluidic devices has strong applications in systems where lipid identification is necessary, common in biofuel research.
Microfluidic devices make possible the study of a single cell to a few hundred cells in a 3D environment. Comparatively, macroscopic 2D cultures have 10 4 to 10 7 cells on a flat surface. [10] Microfluidics also allow for chemical gradients, the continuous flow of fresh media, high through put testing, and direct output to analytical ...
Lab disk for protein structure analysis via small-angle X-ray scattering. The centrifugal micro-fluidic biochip or centrifugal micro-fluidic biodisk is a type of lab-on-a-chip technology, also known as lab-on-a-disc, that can be used to integrate processes such as separating, mixing, reaction and detecting molecules of nano-size in a single piece of platform, including a compact disk or DVD.
Microfluidics has a vast potential for single-molecule studies. In order to detect single molecules, it is often necessary to enhance or amplify a signal of interest. [ 13 ] In bulk methods solutions, an amplified signal from a single molecule will continually be diluted to below the detection limit of nearly every fluorophore or other signal ...
3D Sarfus image of a DNA biochip. The microarray—the dense, two-dimensional grid of biosensors—is the critical component of a biochip platform. Typically, the sensors are deposited on a flat substrate, which may either be passive (e.g. silicon or glass) or active, the latter consisting of integrated electronics or micromechanical devices that perform or assist signal transduction.
Microfluidics deals with the behavior, precise control and manipulation of fluids that are geometrically constrained to a small, typically sub-millimeter, scale. Typically, micro means one of the following features: small volumes(nl, pl, fl) small size; low energy consumption
The main advantage of paper-based microfluidic devices over traditional microfluidics devices is their potential for use in the field rather than in a laboratory. [ 61 ] [ 62 ] Filter paper is advantageous in a field setting because it is capable of removing contaminants from the sample and preventing them from moving down the microchannel.
