Nano-engineered thin-film pH sensors for biomedical and chemical applications

pH sensors are one of the vital devices among biosensors, and the demand has been increasing in various application fields such as medical, biochemistry and environmental. In particular, pH sensors with attractive features such as high pH sensitivity, fast response, high resolution and good stability could lead discoveries in the biomedical domain which could not be observed until now.

Metal oxides-based pH sensors have many attractive features including insolubility, stability, mechanical strength, electrocatalyst and manufacturing technology. Thin film pH sensors prepared by R.F. magnetron sputtering offer many advantages such as ease of packaging, low cost through the use of standard microfabrication processes, miniaturisation, capability of measuring pH at high temperatures, ruggedness and disposability.

In this project we design, develop and test nanoengineered pH sensors for various biomedical applications, including Helicobacter Pylori detection, bone degradation and water-quality monitoring.
