Hybrid Bio-Nano Materials for Artificial Enzyme Design
Lead Research Organisation:

Department Name: Chemical Engineering and Biotechnology
Abstract
Chemical strategies are developed to design mimics of natural, cofactor containing enzymes in order to make them more robust but also to explore the activity enhancement and biomedical applications. To achieve this, modified dopamine is synthesised either to contain flavin or photo-click functional groups to enable further modification. Such dopamine derivatives can either be used for preparation of biopolymeric nanoparticles through dopamine polymerisation or used for nanoparticle (NP) coating. The latter is particularly interesting to enable design of N- based enzymes in which copper or CeO2 NP act as active catalytic centres through externally induced production of reactive oxygen species.

Description | We have developed a nanostructured light activated catalyst that is derived from natural components, showing the ability to catalyse both oxidation and reduction reactions. These reactions were specific to natural enzymes and in particular, the reduction reactions catalysed by the nanostructured photocatalyst were achieved with an enantiomeric excess, a feature that is widely sought after in the pharmaceutical industry for drug targets. We hope to further develop our methodology by introducing more robust nanoparticle elements due to some instability with our initial design. However, thanks to its natural make-up, it has been shown to be biocompatible through in vitro studies and we hope it will have future applications within chemical/energy sectors to aide greener water splitting photocatalysis. In the dark, the material has the potential to be applied in medicinal fields as a drug carrier or antioxidant. |
