Research:

Analytical chemistry, electrochemistry, environmental science, materials engineering, material science, nanomaterials, nanoscience, pharmaceutics and sensors for priority and emerging pollutants

Trending research

The ubiquitous use of pharmaceuticals, both prescribed and over the counter, has resulted in continuous discharge of pharmaceuticals and their metabolites into wastewater. The World Health Organisation (WHO) has classified pharmaceuticals in drinking-water as an “emerging issue” which requires constant monitoring and re-assessment of guidelines for safe water use.   The use of electrochemical sensors as sensitive and selective analytical tools, has been established unequivocally for the evaluation and monitoring of analyte species in the environment, in food, in water and the health industry. Semi-conductive polymers and polymer composites may be readily synthesised as electrochemical transducers onto screen-printed electrodes in the design of highly specific and sensitive analytical devices, that are capable of multi-element analysis, are cost effective and remotely deployable for species evaluation and quantitative analysis. The primary focus of the SARChI chair in Analytical Systems and Processes for Priority and Emerging Contaminants (ASPPEC) is the integrated application of analytical tools and technology to develop early warning systems for trace-level detection and quantification of critical contaminants. These systems are primarily electrochemically driven, but draw on a wide range of supporting analytical techniques and energy sources for feasible outcomes.  In a revolutionary partnership with University Cergy-Pontoise (Paris, France), Baker is Co-director of the first International Associated Laboratory (IAL) established between SensorLab (UWC) and an esteemed external research, teaching and training laboratory.  Baker was appointed as Fellow in Residence on the Paris-Seine Initiative for Excellence (March-June 2020) to cement this partnership, which will offer internationalisation opportunities for many researchers and students alike. The IAL will pursue the synergy of new and renewable energy sources as a complement for sensor operations in the greater scheme of the Internet of Things.
