Research Interests
Analytical chemistry is one of the major sub disciplines of chemistry which aims to study the chemical composition of all matters and to develop tools to elucidate these compositions. Unlike organic and inorganic chemistry, analytical chemistry is about describing chemical systems instead of creating new chemical systems. Without the current analytical methodologies, instrumentations and techniques, it would have been difficult to describe the intricate details of chemical reactions, develop new synthesis approaches or unravel the rules by which chemical systems operate. Due to its interdisciplinary nature, analytical chemistry draws knowledge from disciplines as diverse as engineering, physics and biology, depending on application areas.
Many advances accomplished by analytical chemistry have played critical roles in the sciences ranging from the development of concepts and theories to a variety of practical applications, such as biomedical applications, environmental monitoring, quality control of industrial manufacturing and forensic science. Furthermore, there is an impending urgency on solving health and environmental problems which propagate the importance and relevance of measurement science, necessary to provide us timely and critical information on the state of health of our planet. Modern analytical chemistry focuses on analytical targets and analytical methods. Electrochemistry, which is one such type analytical method, is our group's main research field. The aim of our research programme is to develop new and innovative electroanalytical platform systems for nanoscale chemical and biological analysis in the environmental and health sciences, using electrochemistry methods and approaches.
