Surface modification

Surface modification is the act of modifying the surface of a material by bringing physical, chemical or biological characteristics different from the ones originally found on the surface of a material. This modification is usually made to solid materials, but it is possible to find examples of the modification to the surface of specific liquids. The modification can be done by different methods with a view to altering a wide range of characteristics of the surface, such as: roughness, hydrophilicity, surface charge, surface energy, biocompatibility and reactivity. Surface engineering Surface engineering is the sub-discipline of materials science which deals with the surface of solid matter. It has applications to chemistry, mechanical engineering, and electrical engineering (particularly in relation to semiconductor manufacturing). Solids are composed of a bulk material covered by a surface. The surface which bounds the bulk material is call

Surface Modification with Alginate-Derived Polymers for Stable, Protein-Repellent, Long-Circulating Gold Nanoparticles

Anu Kodiyan

Poly(ethylene) glycol is commonly used to stabilize gold nanoparticles (GNPs). In this study, we evaluated the ability of cysteine-functionalized alginate-derived polymers to both provide colloidal stability to GNPs and avoid recognition and sequestration by the body's defense system. These polymers contain multiple reactive chemical groups (hydroxyl and carboxyl groups) that could allow for ready functionalization with, for example, cell-targeting ligands and therapeutic drugs. We report here that alginate-coupled GNPs demonstrate enhanced stability in comparison with bare citrate-coated GNPs and a similar lack of interaction with proteins in vitro and long in vivo circulation as PEG-coated GNPs.
