Combining monodisperse drop generation with inertial ordering of cells and particles, we describe a method to encapsulate a desired number of cells or particles in a single drop at kHz rates. We demonstrate efficiencies twice exceeding those of unordered encapsulation for single- and double-particle drops.

FAQs
Curing converts liquid PDMS into a stable polymer network through thermal or chemical crosslinking. This transformation fixes the material around the enclosed target and creates a persistent barrier rather than a temporary coating. The resulting structure can protect cells, tissues, sensors, or microfluidic components while retaining the intended geometry of the molded or cast enclosure.
Gas permeability allows gases to move through the PDMS barrier, while the encapsulated design still establishes a defined compartment around the target. This combination can support controlled microenvironments for biological materials and microsystems. In cell or tissue platforms, transport behavior becomes an important design feature because the enclosure must provide protection without completely isolating the enclosed material.
Transparency preserves optical access to the enclosed material or device, allowing observations within the encapsulated structure. Flexibility helps the enclosure conform to microscale geometries and supports integration with components that are not rigid. Together, these properties make the material useful where researchers need both visual access and a mechanically adaptable barrier.
A typical workflow places the selected cells, tissue, sensor, or microfluidic component within a mold or casting arrangement, then surrounds it with liquid PDMS. The polymer is subsequently cured by thermal or chemical means so it crosslinks into a stable enclosure. The procedure therefore depends on controlled placement, complete coverage, and preservation of the desired compartment geometry.
Researchers may select this approach when a project requires a protected compartment with optical access, gas permeability, and integration with microscale components. Supported use cases include organ-on-chip platforms, biosensors, tissue-engineering systems, and compartmentalized cell culture. The technique is especially relevant when biological materials and engineered microsystems must function together within a defined microenvironment.
In organ-on-chip systems, encapsulation can help establish separated compartments for cells or tissues while maintaining access to gases and visual monitoring. For biosensors, it can enclose or integrate sensing components within a microsystem while preserving the device arrangement. These roles connect material processing with experimental control, biological observation, and device protection in bioengineering research.
