| Title | Paper strip detector for detection of 2,4,6-TNP/Picric acid from water, soil and explosives |
| Knowhow is available for | develop a detection kit for trace as well as bulk detection of 2,4,6-TNP |
| Summary | A novel chromen-2-one derivative is coated on polymeric membrane. The paper strip is then exposed to 2,4,6-TNP, and dissolved in acetonitrile. If TNP is present, the color changes from light yellow to green. |
| Advantages | Advantages:
1. Selectivity for sensing 2,4,6-TNP over other nitroaromatic explosives
2. Visual/naked eye detection by colorimetric technique
3. Low detection limit (micromolar range)
4. Compatibility with membrane, cloth, paper
5. Instant detection
6. Simple sample preparation method
