2016
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.

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the properties that they exhibit. Additionally,...

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Polymeric materials are widely used in civil structures, with uses ranging from very soft sealants to more rigid pipes in water and wastewater systems. The most basic definition of a polymer is a molecular structure with repeating subunits. The term polymer comes from Greek, where "poly" means many, and "-mer" means basic unit. Monomers, or single mers, are the specific repeating units. With...

FAQs
Cross-linking density controls how freely polymer chains can move and how much water the network can retain. A more highly cross-linked structure generally restricts chain expansion and alters mechanical behavior, whereas a less densely cross-linked network permits greater swelling. These differences are important when designing hydrogels for biomolecule transport, immobilization, or cell-compatible materials.
Polar and charged groups determine how polymer chains associate with water through hydrogen bonding and electrostatic interactions. These interactions influence hydration, solubility, and the local environment surrounding biomolecules. As a result, functional-group composition can affect whether a polymer remains dissolved, forms a hydrated network, or provides a suitable interface for biochemical applications.
Uncross-linked chains can dissolve and move through solution, while cross-linked chains remain connected in a hydrated network. This structural difference changes how each material handles molecular transport and mechanical forces. Dissolved polymers can support solution-based processing or separation, whereas hydrogels provide a persistent matrix for immobilization, coatings, or controlled delivery.
Composition, chain architecture, and cross-linking density collectively determine water uptake, mechanical behavior, and diffusion. Changing the polymer composition can alter interactions with water, while architecture affects chain organization and network structure. Cross-linking further regulates available space for solvent and biomolecule movement, allowing materials to be tailored for particular biochemical transport requirements.
These polymers can provide hydrated environments in which proteins or other biomolecules are retained within or associated with a polymer-based material. Cross-linked networks are especially useful when a persistent matrix is needed, because the chains do not simply dissolve away. Such immobilization supports biochemical research by maintaining biomolecules in a defined material context.
Hydrophilic polymers support cell-compatible coatings, separation methods, and controlled delivery of proteins or other therapeutic molecules. Their water interactions help create hydrated interfaces, while their network structure can regulate molecular movement. In biochemical and biomedical research, researchers select composition and cross-linking characteristics according to whether the intended outcome is surface compatibility, molecular separation, or sustained transport.
