hemical sensors are generally based on the concomitant
presence of two elements, a recognition element (active
element) sensitive to stimuli produced by various chemical
compounds (analytes) and a transduction element that
produces a signal whose magnitude is related, through a known
relationship, to the concentration of the analyte itself. The use
of silver nanoparticles (AgNPs) as active element in sensors
has a recent story and the rst attempts date back to the early
2000s [1]. In particular the use foe water treatment becomes
very significant in the last years. AgNPs, in comparison for
example with metal oxides, present numerous advantages
such as a high sensitivity, a short response time, room
temperature operation, the possibility of tuning both chemical
and physical properties by using different capping agent. In
the present work, AgNPs were prepared and their interaction
with heavy metal ions was studied using different techniques.
Morphological and dimensional characterizations of the
AgNPs-3MPS (average size and shape) before and after the
interaction with heavy metals were obtained by Transmission
ElectronMicroscopy (TEM) and Dynamic Light Scattering (DLS)
studies. Moreover, the system was investigated by means of
different techniques, such as Uv-vis, Fourier Transform Infrared
Spectroscopy (FTIR) and High-Resolution X-ray photoelectron
spectroscopy (HR-XPS), in order to understand the mechanism
of Surface plasmon resonance (SPR) sensing.

Biography
Venditti I is a Researcher in Inorganic Chemistry in Department of Sciences
at University of Rome Tre, Italy. Her scienti c interests are focused in the
eld of micro and nanostructured materials for advanced technological ap-
plications. The preparation of such structures material used was noble met-
als (Au, Ag, Pt and Pd) and polymeric materials (organometallic polymers,
polyenes and polyacrylates) obtained in nano micrometric dimensions and
controlled shape through different approaches. These research activities
have been reported in 70 papers in international peer-reviewed journals, two
book chapters and two patents.
