Modification of electrodes with self-assembled, close-packed AuNPs for improved signal reproducibility toward electrochemical detection of dopamine

Electrochemical sensors benefit from low cost and fast detection speeds, which makes them suitable for routine analysis of small biological molecules such as dopamine (DA). DA is a neurotransmitter that plays an important physiological role and can be used as a marker for conditions such as depressi...
