The phrase "allow for diffusion" is correct and usable in written English.
It can be used in contexts discussing processes where diffusion is a factor, such as in science or social dynamics.
Example: "The design of the experiment must allow for diffusion to ensure accurate results."
Alternatives: "permit diffusion" or "facilitate diffusion".
Once inserted into the membrane, hemi-channels (connexons) allow for diffusion of ions and small molecules (<1 kDa) between the extracellular space and the cytosol.
These structures are at the same time flexible enough to allow for diffusion of solvent and ligand into and out of the networks.
This structure is at the same time flexible enough to allow for diffusion of solvent and analytes into and out of the network.
However, communications via those molecules require the presence of the both sender and receiver species in the same liquid environments or in gel-like setting within a short distance to allow for diffusion of signaling molecules.
Further, we allow for diffusion in the bulk material; we allow the composition of material transferred across the interface to differ from the compositions of either phase, with solute drag included as a special case; and we allow for heat flow in both phases.
The needle was left in this place for 5 min to allow for diffusion before slow withdrawal.
Tracer transport is described by advection/dispersion along the fracture allowing for diffusion into an immobile matrix.
The study is achieved by putting two binary phases in contact and allowing for diffusion of both components in either phase.
An inherent drawback for hydrogel, however, is the limited pore size in the polymeric network, which only allows for diffusion of medium, metabolites, and nutrients, but hinders migration of transplanted cells out of the carrier.
An additional minute was allowed for diffusion and prevention of backflow through the needle track before the injector was withdrawn.
