ABSTRACT

This chapter focuses on the description of physical properties and technological characteristics of nanophotonic sensors for polycyclic aromatic hydrocarbon (PAH) detection in water objects. The developed nanophotonic sensor includes optically transparent working electrode (WE) modified by quantum-dimensional structures such as spherical semiconductor quantum dots (QDs). The monomolecular layer of QDs is plotted onto the WE surface by Langmuir-Blodgett (LB) technology. Particular attention is paid to the processes of the assay in the nanophotonic sensor. As a typical PAH representative benzo[a]pyrene (BP) was chosen which possesses the known carcinogenic property. The developed nanophotonic sensor can be used in ecology for organic carcinogens detection in water objects of the environment as well as for biomedical, physical chemical assays and some others.
