Recent Findings from Hanyang University Has Provided New Information about Nanoparticles (Nano-functionalization of protein microspheres)

August 1, 2014

By a News Reporter-Staff News Editor at Science Letter -- New research on Nanoparticles is the subject of a report. According to news reporting from Seoul, South Korea, by NewsRx journalists, research stated, "Protein microspheres are promising building blocks for the assembly of complex functional materials. Here we demonstrate a set of three techniques that add functionality to the surface of protein microspheres."

The news correspondents obtained a quote from the research from Hanyang University, "In the first technique, a positive surface charge on the protein spheres is deposited by electrostatic adsorption. Negatively charged silica and gold nanoparticle colloids can then electrostatically bind reversibly to the microsphere surface. In the second technique, nanoparticles are covalently anchored to the protein shell using a simple one-pot process. The strong covalent bond between sulfur groups in cysteine in the protein shell irreversibly binds to the gold nanoparticles. In the third technique, surface morphology of the protein microsphere is tuned through hydrodynamic instability at the water-oil interface. This is accomplished through the degree of solubility of the oil phase in water."

According to the news reporters, the research concluded: "Taken together these three techniques form a platform to create nano-functionalized protein microspheres, which can then be used as building blocks for the assembly of more complex macroscopic materials."
