Effective nanosensors for the selective detection of metal ions

Farhat Ikram

Transition metal nanoparticles of plant based polyphenols were synthesized. Conjugation of metal with plant based polyphenol was confirmed by FT-IR, UV-visible spectroscopy and Dynamic light scattering (DLS). To examine their potential and chemical sensing property, different metal salt solutions were screened. Only one metal ion altered the absorption intensity while others did not produce any change in absorption intensity of nanoparticles. The sensing ability of synthesized nanoparticle was checked in biological samples (plasma, serum) and environmental samples (tap water). The stability of nanoparticles was checked at elevated temperature (100 0C). For in vivo and in vitro studies stability was also checked at different concentrations of NaCl (1-100 µM).
