Preparation and Application Some thiol Surfactants With Nanoparticles as sensors for metals

In this study we synthesized three series of thiol surfactants. The chemical structure of the synthesized surfactants was confirmed using the spectroscopic techniques (IR, 1HNMR).Colloidal solution of Gold nanoparticles was prepared. The self-assembling of the synthesized dithiol and para aminothiol surfactants on gold nanoparticles was investigated. The synthesized dithiol and para-aminothiol surfactants and their nanostructures In addition we investigated the fabrication of surface Plasmon resonance (SPR) nanosensor using gold nanoparticles (AuNPs) chemisorbed onto self-assembled monolayer of meta-aminothiol surfactants on gold substrate. The fabricated SPR nanosensor of 10-(3-aAlso, In the present study newly developed potentiometric sensors for determination of zinc(II) are presented. The modified potentiometric method was based on the fabrication of modified carbon paste (C5-CPE; electrode X) and modified gold nanoparticles-c
