Zusammenfassung: | Dopamine is a biomolecule that plays an important role in controlling
brain function. The concentration of dopamine is a critical parameter
in biotechnology. In the present research, a novel methodology for
synthesis of a chitosan/polyaniline-gold-nanoparticle nanostructure
layer by using the laser ablation technique is developed. The novel
polyaniline nanostructure composite layer was coated on the surface of
the photonic crystal with 28 alternating layers of SiO
2
and
TiO
2
by an electron gun deposition machine. By implementing
the reflectance set-up, a photonic
crystal/chitosan/polyaniline-gold-nanoparticle was used to measure the
low concentration of dopamine by the lowest concentration of dopamine
set to 1 ppm. The results propose a new approach and future
directions in sensor-based techniques. |
