Here, we present a robust method to physically immobilize liquid–liquid phase-separated condensates within a porous low-melting agarose hydrogel matrix without disrupting their internal liquid dynamics. The approach minimizes droplet sedimentation, coalescence, and surface-wetting artifacts, enabling reproducible imaging and quantitative biophysical analysis over periods of hours.

FAQs
Diffusion through the gel controls how immobilized material interacts with its environment. The interconnected pores permit substrates and nutrients to enter and products to leave, while the matrix retains enzymes, cells, or other biological components. This separation allows catalytic or cellular activity to continue without requiring the material to remain dispersed in solution.
Agarose immobilization relies on a balance between containment and molecular access. If pores retain the biological component while remaining open to surrounding solutions, substrates can reach active sites and products can diffuse away. This balance explains why the matrix can support repeated use while preserving biological function.
The relatively mild and chemically stable nature of agarose helps protect biological function during confinement. That property matters when the immobilized component must continue catalysis or cellular activity rather than merely remain physically trapped. In practice, preserving function supports more consistent processing and makes the material easier to recover for reuse.
Compared with biological material kept free in solution, immobilization adds a physical recovery advantage: the matrix helps retain the component while the surrounding solution remains accessible. This arrangement can simplify repeated use and reduce the difficulty of recovering dispersed material after each operation, while diffusion preserves access to substrates and products.
A basic workflow for Agarose immobilization starts by combining the biological component with molten agarose. Cooling then converts the mixture into a gel that confines the component within its pore network. The resulting preparation can be placed in contact with surrounding solutions, allowing substrates, nutrients, and products to move through the matrix while the immobilized material remains available for further use.
The technique supports several distinct biological uses. Immobilized enzymes can perform catalysis, while entrapped cells can carry out whole-cell biotransformations. Agarose matrices also support biosensor development and controlled studies of cellular activity. Across these applications, the shared practical value is access to the surrounding solution combined with retention of the biological material, which can improve recovery and process consistency.
