Detecting biological structures via a rapid and facile method has become a pronounced
point of research. Dopamine (DA) detection is critical for the early diagnosis of a variety of
neurological diseases/disorders. A study on the real-time optical detection of DA is
described here using graphene oxide (GO) functionalized with chitosan (Cs). Hence, a
computational model dependent on a high theoretical level density functional theory (DFT)
using the B3LYP/LANL2DZ model is carried out to study the physical as well as electronic …
