Precision synthesis using nanoscale electrochemistry

   Warwick Centre for Doctoral Training in Analytical Science

   Applications accepted all year round  Funded PhD Project (European/UK Students Only)

About the Project

The emergence of nanoscience and technology is regarded as a modern day industrial revolution, stimulating significant scientific, economic, and social development. The revolution is driven by the fabrication of functional nanomaterials which are materials with length scales on the order of billionths of a metre (1 – 100 nm = 10-9 – 10-7 m) in at least one lateral dimension. At surfaces, these are typically achieved using probe-based methods to print materials in 2D/3D. However, in priority research areas such as healthcare (e.g. drug delivery, diagnostics, etc.), and energy-related technologies (Li-ion batteries, supercapacitors, etc), there is sustained demand for smaller dimensions, higher resolution and better properties, which can be met through the development of probe-directed organic, macromolecular and supramolecular synthesis at surfaces

During this project we will develop novel methods of precision, nanoscale synthesis by adapting scanning electrochemical cell microscopy (SECCM) for simultaneous synthesis and deposition of organic molecules, including polymers, at and from surfaces. We will identify suitable electrochemically-mediated transformations on a batch scale using an ElecraSyn Pro 2.0. These reactions will then be translated to the nanoscale, using a bespoke electrochemical scanning rig, enabling precise electrochemical synthesis and analysis at functional surfaces. This will contribute to the long-term aim of translating macroscopic electrochemical synthesis methods, to the nanoscale, which will enable 3D control over surface modification. Ultimately, this represents a novel and alternative strategy for surface modification and patterning of conducting (e.g. electrodes), insulating (e.g. polymeric) and biological (e.g. cells) substrates.
