Collagen is a core component of the ECM, and provides essential cues for several cellular processes ranging from migration to differentiation and proliferation. Provided here is a protocol for embedding cells within 3D collagen hydrogels, and a more advanced technique for generating randomized or aligned collagen matrices using PDMS microchannels.

A microchannels-on-a-chip platform was developed by the combination of photolithographic reflowable photoresist technique, soft lithography, and microfluidics. The endothelialized microchannels platform mimics the three-dimensional (3D) geometry of in vivo microvessels, runs under controlled continuous perfusion flow, allows for high-quality and real-time imaging and can be applied for microvascular research.

PCR: The Polymerase Chain Reaction

2023
The polymerase chain reaction, or PCR, is a technique used to amplify DNA through thermocycling – cyles of temperature changes at fixed time intervals. Using a thermostable DNA polymerase, PCR can create numerous copies of DNA from DNA building blocks called dNTPs. There are three steps in PCR: denaturation, annealing, and elongation. Denaturation is the first step in the cycle and causes the DNA to melt by disrupting hydrogen bonds between the bases resulting in single-stranded DNA. Annealing...
FAQs
The cycle repeatedly applies denaturation, primer annealing, and polymerase-mediated extension to amplify targeted DNA. Because these stages require controlled temperature changes, the microchannel’s small dimensions allow rapid heat transfer and precise temperature control. That combination supports repeated cycling in a compact reaction environment and can shorten processing time for genetic analysis.
Miniaturization reduces the amount of sample and reagents required for each reaction. Narrow channels and small chambers also create a compact environment in which temperature changes can be controlled precisely. These features support rapid processing while conserving materials, making the format useful for systems designed for compact genetic analysis and molecular testing.
Pumps and valves can support fluid handling within an integrated microfluidic device, while sensors help monitor system conditions. Optical or electrical readouts provide ways to detect or report reaction results. Together, these components can support automation and connect amplification with measurement, helping transform a reaction chamber into a portable molecular-testing platform.
A typical workflow places the sample and required reagents in the microfluidic system, establishes controlled temperature conditions, and repeatedly carries out denaturation, primer annealing, and polymerase-mediated extension. Integrated pumps or valves may manage fluid movement, while sensors and optical or electrical readouts support monitoring. The resulting amplified DNA can then inform genetic analysis.
Researchers may select this format when they need targeted DNA amplification while limiting sample and reagent volumes. Its compact design is relevant to pathogen detection, mutation screening, and genetic analysis. The technology is especially useful when reduced processing time, integrated measurement, or a portable testing format is important to the research or diagnostic objective.
In bioengineering, PCR microchannels provide a route for combining amplification, fluid handling, temperature control, sensing, and signal readout within one compact platform. Such integration can contribute to automated devices for molecular testing and support point-of-care applications. The resulting systems are suited to portable genetic analysis, pathogen detection, and mutation screening where compact operation is valuable.
