Microchannel in microtechnology is a channel with a hydraulic diameter below 1 mm, usually 1–99 μm.[1] Microchannels are used in fluid control (see Microfluidics), heat transfer (see Micro heat exchanger) and cell migration observation.[2] They are more efficient than their 'marco' counterparts, because of a high surface-area to volume ratio yet posses a multitude of challenges due to their small size.[3]
Materials[edit]
Different types of materials are required for the different uses of microchannels. These are the three main categories.[4]
Polymeric and glass substrates[edit]
polymethyl methacrylate (PMMA) is used as a solution to a wide range of microfluidic devices due to it's low cost and easier fabricating methods.[4] Silicon elastomers can be used for situations in which elasticity and deformation is necessary.[5]
Metallic substrates[edit]
Metallic substrates are often chosen for their advantageous metallic properties, such as withstanding high temperatures and transferring heat faster. They can be subject to corrosion.[4][6]
Semiconductors, ceramics and composites[edit]
History[edit]
The concept of the microchannel was proposed for the first time by researchers Tuckerman and Pease of Stanford Electronics Laboratories in 1981.[7] They suggested an effective method for designing microchannels in the laminar and fully developed flow.[8]
Common uses[edit]
Microchannels are extensively used in the pharmaceuticals, and biochemical industries due to short diffusion distances, higher interfacial area, and higher heat/mass transfer rates.[9]
