The nanofibers were coated with layers of polyaniline-titanium dioxide (PANi-TiO2) combination using an air brush. The structure, morphology, and electrical characteristics of the nanoparticles and nanofibers were characterized by SEM, FT-IR, and electrical measurement methods. The results indicated that the produced nanofibers exhibited a strong in vitro interaction and selectivity against acetone gas, a biomarker of diabetes. Perovskite nanoparticle doped PAN nanofibers have shown approximately 43% change in resistance with acetone gas exposure. These findings suggest that PrFeO3-doped nanofibers hold promise as potential candidates for acetone gas sensors in non-invasive diabetes monitoring.eninfo:eu-repo/semantics/openAccessNanofiberAcetoneGas sensorNon-invasiveDiabeticsPerovskitesArticle10.29228/JIENS.70059321531661189892
