We propose a simple self-assembly technique of silica colloidal nanoparticles to create a nanofluidic junction between two microchannels in polydimethylsiloxane (PDMS). Using this technique, a nanoporous bead membrane with a pore size down to ~45 nm was built inside a microchannel and applied to electrokinetic preconcentration of DNA samples.

Microfluidic double emulsions generation typically involves devices with patterned wettability or custom-fabricated glass components. Here we describe the fabrication and testing of an all polydimethylsiloxane (PDMS) double emulsion generator that does not require surface treatment or complicated fabrication processes, and is capable of producing double emulsions down to 14 µm.

FAQs
Channel geometry affects fluid movement by defining the routes available for transport and the conditions under which liquids mix. In combination with surface properties, geometry helps determine how small fluid volumes move through the chip. Researchers can therefore design patterned channels to control transport and mixing for biological experiments while using minimal sample and reagent volumes.
Surface properties influence how liquids interact with channel walls, making them a key design variable alongside channel geometry. Those interactions affect transport and mixing, so controlling surface characteristics can help researchers obtain the intended fluid behavior. This is particularly relevant when a chip must handle small biological samples or reagents consistently within patterned microchannels.
Pressure-driven flow uses an applied pressure to move liquid, whereas capillary flow relies on capillary forces within the microchannels. Both provide ways to transport fluids through the chip, but they represent different control mechanisms. Selecting between them allows researchers to match fluid movement to the requirements of a bioengineering experiment or lab-on-a-chip design.
The process begins by molding PDMS against a microscale template to create the channel pattern. The molded material is then bonded to a substrate, producing the assembled fluidic device. This workflow combines microscale patterning with assembly, supporting rapid prototyping of chips for bioengineering experiments and lab-on-a-chip development.
In bioengineering, these chips can support cell culture, biochemical assays, tissue models, and lab-on-a-chip systems. Their small internal volumes suit experiments that require only limited sample and reagent quantities. The same platform can also contribute to compact diagnostic development, linking microscale fluid handling with biological testing and model systems.
Optical transparency, flexibility, and rapid prototyping are important characteristics that extend the usefulness of these chips beyond fluid handling alone. Together, they support adaptable device development and make the platform valuable for studying biological processes. These features also assist efforts to develop compact diagnostic platforms within bioengineering and lab-on-a-chip research.
