With lower limits of detection and increased stability constantly being demanded of biosensor devices, characterisation of the constituent layers that make up the sensor has become unavoidable, since this is inextricably linked with its performance. This work describe the optimisation and characterisation of two aspects of sensor performance: a conductive polymer layer (polyaniline) and the immobilised protein layer. The influence of the thickness of polyaniline films deposited electrochemically onto screen-printed electrode surfaces is described in this work in terms of its influence on a variety of amperometric sensor performance characteristics: time to reach steady state, charging current, catalytic current, background current and signal/background ratios.

Article Synopsis
  • The study examined Polar ZnO surfaces with O- and Zn-termination using advanced microscopy techniques, revealing that adsorbed fluid layers significantly influence their adhesion properties in air.
  • The O-terminated surface was found to have a thicker fluid layer and higher particle density compared to the Zn-terminated surface, suggesting a difference in how they should be prepared for specific applications like epitaxy.
  • The findings propose that these adsorbed fluid layers might play a crucial role in the growth of certain ZnO nanostructures, helping to clarify previous inconsistencies in research.
