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
PDMS’s tunable elasticity lets investigators adjust how the construct responds to controlled deformation, while its transparency supports optical imaging of those changes. Geometry can also be varied to reproduce selected anatomical features rather than a complete eye. Together, these properties allow bioengineers to examine optical and mechanical behavior under repeatable laboratory conditions.
Layered layouts create separate structural or fluid-handling regions within the construct. Chambers can represent spaces where fluids are introduced or monitored, while microfluidic channels provide controlled flow paths. Combining these features allows researchers to coordinate fluid movement, optical observation, and mechanical deformation in one experimental platform, supporting studies that require more than a simple molded shape.
A PDMS eye model reproduces selected anatomical, optical, or mechanical features instead of the full complexity of a living eye. This simplification makes geometry, material response, fluid flow, and deformation easier to control and observe. Its role is therefore complementary: it provides a repeatable benchtop system that can connect focused experiments with more complex biological behavior.
Fabrication generally begins by defining the desired geometry through molding or soft lithography. PDMS is then shaped into layers, chambers, or microfluidic channels and cured so the structures retain their intended form. The resulting transparent construct can be configured for fluid flow, optical imaging, or controlled deformation, depending on the experimental objective.
Researchers can use this platform when they need controlled testing of ocular biomechanics, ophthalmic devices, or surgical approaches. Its adjustable geometry and elasticity support mechanical studies, while transparency enables optical observation during experiments. The same type of construct can also reproduce selected aspects of eye disease or drug delivery in a more accessible setting than a complex biological system.
Experiments can reveal how a designed ocular structure behaves during deformation, how fluids move through defined channels or chambers, and how optical imaging captures those processes. The models also support evaluation of device performance and surgical strategies. Because each feature can be controlled separately, results help investigators assess specific mechanisms before moving toward more complex biological studies.
