This article presents a protocol for the production of protein-based nanoparticles that changes the hydrophobic surface to hydrophilic. The produced nanoparticle is an assembly of gliadin-cyanoacrylate diblock copolymers. Spray coating with the produced nanoparticle changes the surface of target material to a hydrophilic surface.

We present a protocol to synthesize Janus microhydrogels composed entirely of the same base material, poly(N-isopropylacrylamide) (PNIPAAm), with a clearly compartmentalized structure base on the phase separation of a supersaturated NIPAAm monomer solution. The synthesized Janus microhydrogels show unique properties such as anisotropic thermo-responsiveness and organophilic/hydrophilic loading capability.

This study describes classical hydration using the thin lipid film method for nanoliposome preparation followed by nanoparticle characterization. A 47 kDa-hydrophilic and globular protein, tarin, is successfully encapsulated as a strategy to improve stability, avoid fast clearance, and promote controlled release. The method can be adapted to hydrophobic molecules encapsulation.
FAQs
Performance depends on how the modification changes the water-facing interface. Polar or charged groups can strengthen interactions with water, while a hydrophilic coating places water-compatible chemistry at the surface. Altering surface morphology provides another route to improve spreading. Engineers can therefore tune wettability through chemistry, added layers, physical structure, or combinations of these approaches.
Polar or charged groups increase the surface’s affinity for water by providing sites that support stronger interactions at the interface. This can help water spread across an engineered material rather than remain poorly distributed. In applications where unwanted material attachment is a concern, the resulting interfacial changes may also reduce nonspecific adsorption and support more reliable performance.
Surface morphology offers a physical route for influencing how water contacts a material. Restructuring the surface can make water spread more readily, changing wettability even when the main chemical composition remains unchanged. This option is relevant when engineers need to control interfacial behavior through surface structure, either independently or alongside polar groups and hydrophilic coatings.
Improved water affinity can reduce nonspecific adsorption, meaning unintended attachment of substances to a surface. Stronger water interactions and more favorable spreading change the interface encountered by aqueous materials. This benefit is especially relevant to biomaterials, sensors, and other systems where unwanted surface accumulation could interfere with biocompatibility, function, or measurement reliability.
Engineers can introduce polar or charged chemical groups, apply a hydrophilic coating, alter surface morphology, or combine these routes. The choice depends on whether the design priority is stronger water interaction, improved spreading, reduced nonspecific adsorption, or controlled interfacial behavior. These options provide multiple ways to adapt a material for contact with aqueous environments.
The approach supports biomaterials, microfluidics, filtration membranes, sensors, and fluid-handling devices. In biomaterials, improved wetting can contribute to biocompatibility; in microfluidics and fluid handling, it can aid liquid transport. Membranes and sensors can benefit from altered interfacial behavior, including fouling resistance or more reliable measurements in aqueous operating environments.
Hydrophilic functionalization connects surface chemistry and physical structure with practical control over aqueous interfaces. By changing wettability and water interactions, engineers can influence liquid transport, nonspecific adsorption, fouling resistance, biocompatibility, and measurement reliability. Its broad relevance comes from applying the same interfacial design principle to different materials, devices, and water-contacting engineering systems.
