17 -Estradiol (E2) residues in food with concentration range even as low as 1-10 pM can cause serious diseases such as early puberty in children and can also increase the risk of ovarian and breast cancer in women. In this work, we report on the development and optimization of an impedimetric sensor for high sensitive detection of E2 based on Molecularly Imprinted Polymer (MIP). The MIP layer was synthesized via electro-polymerization by cyclic voltammetry onto gold nanoparticles (AuNPs)-modified screen printed carbon ink electrode (SPCE). |
