Multifunctional plasmonic nanostructures for biomedical application

Abstract

The work in this thesis focuses on developing a new class of multifunctional Au nanomaterials with integrated plasmonic and magnetic properties have been developed for synergistic biosensing, bioimaging and therapeutic applications. Taking advantage of a unique array of properties, such as localized surface plasmon resonance (LSPR), surface-enhanced Raman scattering (SERS), and enzyme-mimicking catalysis, I have explored their applications in optical sensing, imaging, and targeted therapy. My results have demonstrated that the structural integration of the plasmonic and magnetic components in these nanostructures complement each other in the biomedical applications, leading to excellent performance that cannot be achieved using individual building blocks.
