Optical Detection Of Toxic Cations And Anions By Nanocomposite Materials

Nanocomposite materials have appeared as appropriate replacements to overcome the limitations of microcomposites and simple nanomaterials. There is an upsurge of interest in nanocomposite materials due to the significant applications and all the research areas related to chemical, physical and biological sciences. Making composites with the combination of nanomaterials could convert them into superior materials for the sensing analytes, such as anions, cations, biomolecules, explosives, toxic gases, food toxins and organic compounds. This chapter emphasizes only on the recent investigations of nanocomposite materials for the detection of toxic metals and anions by optical detection methods, such as fluorescent and colorimetric methods. Appropriately selected examples are discussed in detail.
