A consortium is creating innovative steel oxide nanocomposite materials that have a wide range of applications. These range from assisting the delivery of drugs to helping cleanse up the natural environment. Core-shell materials, where nanoparticles of a particular element are covered with another substance, can have many programs in nanotechnology and nanomedicine. An initiative has developed a procedure for applying unique proteins from marine organisms to nanoparticles to produce core-shell materials. The project investigated the application of marine metal-oxide-forming enzymes and multicopper oxidase (MCO) enzymes from marine germs. It also concentrated on a type of laccase enzyme derived from marine sponges, that can be used to produce steel oxide nanocomposite materials. Project partners immobilised a sponge laccase on magnetic iron oxide nanoparticles . In addition, the enzyme can be used together with silica or other steel-oxide-forming proteins to render nanoparticles containing multiple shells of metal oxides such as titania. The photocatalytic and ferromagnetic properties of the titania-iron oxide nanoparticles allowed the development of a technique for fast and efficient removal of bacteria applying a novel magnetic nanoparticle separator. Core-shell nanoparticles developed by the consortium will be used in the remediation of contaminated sites by the removal of germs and hefty metals. The nanoparticles can additionally be utilized for developing anti-fouling strategies.
