|a Polymer capsules are an interesting concept considered in nanobiotechnology. Approaches that facilitate their assembly remain sought after. Poly(dopamine) (PDA) has been considered and successfully applied in this context. We recently demonstrated that PDA could be copolymerized with different types of poly(N-isopropylacrylamide) (pNiPAAm) to assemble mixed films on planar substrates. Herein, we transferred this approach onto colloidal substrates and characterized the film thickness depending on the film composition and template particles size. While the membrane of capsules assembled using 5 μm template particles exhibited strong dependency on the film composition, smaller templates led to capsules with similar membrane thickness. We then compared the permeability of different capsules using fluorescently labeled dextran and fluorescein. We found that the permeability of capsules was heavily dependent on the polymer composition and the template particle size. These fundamental findings contribute to the potential of these capsules, assembled in one-step, for biomedical applications
