Nanoscale functional materials and devices for biomedical applications

Nanostructured materials show great potential in the biomedical field as they can serve as superior bioimaging contrast agents, diagnostic and therapeutic tools. Antibacterial nanosilver, plasmonic nanosized noble metals, quantum dots, nanophosphors and superparamagnetic nanoparticles constitute some of such functional materials. For example, nanoparticles that emit light light upon excitation (e.g. nanophosphors, quantum dots), superparamagnetic (e.g. Fe2O3) and plasmonic nanoparticles (e.g. Au, Ag) can be used as “nanotools” in bio-applications. Here, we synthesize such nanoparticles and investigate the parameters that influence their properties, targeting superior performance in diagnostics and therapeutic applications. Novel nanoscale systems and devices will be fabricated using such functional materials aiming to tackle specific medical and pharmaceutical problems.
