Research interests

My research group focuses on the development of advanced nanomaterials and translating these towards biomedical applications. By understanding the fundamental physics behind the materials we synthesize we strive to make leaps forward in the fields of Nanotechnology and Nanomedicine. The three themes that we currently study are:

Quantum dot technology. We synthesize and develop cadmium based and cadmium-free quantum dots for advance biomedical imaging technologies. As well as development of biocompatible materials, we are also working towards quantum dots with bimodal properties. Our aim to expand activity in this area and will be offering PhD, and PDRA opportunities.

Nanowires. We synthesize and characterize semiconductor (ZnO, CdTe, PbTe) and metallic (Au, Ni, Cu, Zn, and Ag) nanowires. The main focus is to understand and use the properties introduced by nanoscale effects. We study the tranposrt properties using multiprobe scanning probe microscopy in combination with an SEM. Material properties are studied by TEM/

Nanoparticles. We synthesize and study functionalised nanoparticles to improve the understanding of nanoparticle interactions with biological systems.
