A ultrasensitive NiFeP based electrochemical sensor was developed for the selective electrochemical detection of dopamine to address the issue associated with neurological disorders including Parkinson's and Alzheimer's diseases. The novel sensor shows superior selectivity and sensitivity with a lowest detection limit of 0.3 nM and a wide detection range of 10 nM-500 mu M and is immune to the interference of ascorbic acid at physiological pH (7.4). A novel flexible sensor was developed with NiFeP coated over Whatman filter paper, which exhibits two liner ranges of 10 nM(-1)mu M and 10 mu M-500 mu M with an ultra high sensitivity of 756 mu A mu M(-1)cm(-2)and 4.6 mu A mu M(-1)cm(-2)respectively with a wide detection range of 10 nM to 500 mu M.
