- •
The nano film showed sensitivity and selectivity toward Fe3+ and further toward PPi.
- •
The film shows a distinct color change from colorless to pink.
- •
The sensor can detect Fe3+ quantitatively in concentration range of 100–2000 μM.
- •
The calculated low detection limit (LOD) value could be 1.19 μM for Fe3+.
- •
The intensity at 564 nm linearly decreases with PPi concentration from 50 to 3000 μM.
- •
The calculated low detection limit value is 1.75 μM for PPi.
