The synthesised nanocomposites were systematically analyzed using XRD, FT-IR, Raman spectroscopy, HR-SEM and HR TEM analysis to assess structural, optical, and morphological properties. The antimicrobial and antibiofilm efficacy was evaluated against drug-resistant strains, including <i>Escherichia coli</i> and <i>Klebsiella pneumoniae</i>, by well diffusion method and crystal violet-Microtitre plate (CV-MtP) method. Notably, the NiZrO₃@MWCNT composite exhibited a maximum antibacterial inhibition zone of 13 mm and showed superior biofilm inhibition of 92.8% against K. pneumoniae at 500 ppm. In contrast, NiZrO₃@GNP demonstrated a biofilm inhibition of 97% at 500 ppm. Furthermore, the microplate Alamar Blue assay (MABA) was employed to determine the minimum inhibitory concentration (MIC) against <i>Mycobacterium smegmatis</i> (MTS) with NiZrO₃@MWCNT achieving 96% inhibition and at 500 ppm. These results confirm the enhanced antimicrobial efficacy of the carbon-integrated nanocomposites over pure NiZrO₃, which showed limited activity.
