Precise VOC detection is essential for non-invasive disease diagnosis, with breath analysis as a simplified approach. However, metal oxide sensors struggle with selectivity and low-temperature operation. This work presents strategies to optimize metal oxide-based chemiresistors for acetone sensing. Two approaches were explored: (1) SnO2nanoparticles functionalized with Zn(II) tetraphenylporphyrin (ZnTPPF20) and (2) a porous ZnO network hybridizedwith MWCNTs/PANI. Both composites demonstrated excellent low-temperature performance.

Abstract
Precise VOC detection is essential for non-invasive disease diagnosis, with breath analysis as a simplified approach. However, metal oxide sensors struggle with selectivity and low-temperature operation. This work presents strategies to optimize metal oxide-based chemiresistors for acetone sensing. Two approaches were explored: (1) SnO2nanoparticles functionalized with Zn(II) tetraphenylporphyrin (ZnTPPF20) and (2) a porous ZnO network hybridizedwith MWCNTs/PANI. Both composites demonstrated excellent low-temperature performance.
