1. Summary
Generally, I prepared different organic and metal oxides compounds for sensing some of highly toxic metals that affect in human health. The prepared organic compound is characterized via HNMR, IR techeniques. Signficently, our result show that the organic and metal oxides compounds are prepared prefectly.

2. Experimental
I used various machines and facilities such as NMR for measuring organic compound samples using chloroform as asolvent, FTIR machine for measuring the functional group in some metal oxides and organic compound, raman machine for characterization of metal oxides and organic compound, zeta potential for calculating the isoelectric point of metal oxides at different pH, and microplate reader for determine the cytotoxcity of my fabricated material.

3. Results and Discussion
The various machines and facilities such as HNMR, FTIR, and Raman spectroscopy allow me to investigate and confirm the exact preparation and functional groups of prepared optical probe. Our results show that all compounds are prepared as predicted.
