Preparation and characterization of polyaniline-Cu-Ni nanocomposite thin film sensors for detection of pathogenic Leptospira

This research was conducted to study on PANI-Cu-Ni nanocomposite thin film sensors for Leptospira detection. PANI-Cu-Ni nanocomposite was deposited onto glass substrate by spin-coating technique. The morphological and structural properties of the thin films have been analysed using atomic force micr...
