Nanomaterials present novel properties with the possibility of new contributions in the forensic science field. Determination of drugs, xenobiotics and heavy metals are critical in the elucidation of poisoning and death. Nanomaterials can be applied to the analysis of trace evidence; gunshot residues, heavy metals and halogenated organics materials. In this work we use nanostructure materials for detection of toxic agents in water samples. We successfully achieved the synthesis of Ag, Au, ZnO and CdS nanoparticles using microwave technology. In this work we summarized the nanoparticles interactions with water samples containing different quantities of heavy metals and chlorinated compounds. Characterization of these materials was performed using UV-Vis spectroscopy, IR, TEM and XRD techniques. Our study will contribute in the elaboration of new simple methods, providing better detection limits.
