Executive Industry Relevance

This protocol enables precise control over solute release kinetics through tunable plasma polymer shell thickness, directly supporting mechanistic de-risking in early-stage drug delivery formulation. By quantifying permeability via ionic conductivity measurements, it provides predictive confidence for sustained release profiles, informing go/no-go decisions in preclinical candidate selection. The approach addresses a key translational gap: adapting flat-substrate thin-film deposition to particulate systems for reproducible nanomaterial synthesis.
