Nanocomposite sensors of polyaniline-Zn-Ag for the detection of pathogenic leptospira bacteria in environmental water

This research is focused on the fabrication of a sensitive, durable and user-friendly polyaniline-Zn-Ag (PANI-Zn-Ag) nanocomposite thin film sensor for Leptospira bacterial detection. This study focuses on the performance of different concentration ratios of PANI-Zn-Ag nanocomposite thin films. The...

These specific morphological properties are required to maximize the reaction between the particles in PANI-Zn-Ag and the bacterial cells to increase the sensitivity. The repeatability and stability test showed a standard deviation range of 0.0005–0.001, which indicates that the PANI-Zn-Ag thin film sensor has high reusability.
