fast scan cyclic voltammetry seems to be the best available tool for sensing neurochemicals (such as glucose, dopamine) while providing excellent sensitivity and specificity, then why do scientists bother developing new surface electrode with different materials (CNT, graphene, conducting polymer) while using other voltammetries (direct pulse voltammetry, cyclic voltammetry)?
Because Cyclic Voltametry (CV) is not sensitive enough to detct lower concentrations and that cant achive the the detction limits neededd for todays requirments. Other thing is CV is not selctive enough to detct the tose compounds at ng/L in our body whilest they are present in a very complex bady fluids matrix.
In Fast Scan Cyclic Voltammetry back ground current was larger
