چکیده
Ultrasensitive photoelectrochemical immunoassay of polycyclic aromatic hydrocarbon (PAH) is proposed using an antibody-modified nanostructured TiO(2) electrode combined with bifunctional gold nanoparticles modified with the PAH antigen and horseradish peroxidase (HRP). The HRP-catalyzed reaction prompts the electron transfer between the electrode and electrolyte causing an excellent photocatalytic performance.

متن کاملSERS detection of polycyclic aromatic hydrocarbons using a bare gold nanoparticles coupled film system.
A facile approach based on a bare gold nanoparticles (Au NPs) coupled film system as the surface-enhanced Raman scattering (SERS) substrate was developed for the effective detection of polycyclic aromatic hydrocarbons (PAHs). A smooth gold film (Au film) was self-assembled with a hydrophobic layer of an alkyl chain in order to capture the PAHs molecules from bulk solution to its surface. Next, ...
