In article number 2004146, Hadar Ben‐Yoav and co‐workers introduce a sensory device that can test unprocessed urine and quantify dopamine levels. By utilizing intelligent chemometric models for fingerprint identification, the device detects and separates overlapping electrochemical signatures in urine to arrive at its solution. Being able to rapidly detect the dopamine levels in urine is highly advantageous...
Designing functional materials as electrode coatings to transduce high‐quality information about redox molecules in biofluids is crucial for developing the next‐generation medical devices. Rapidly analyzing the neurotransmitter dopamine (DA) urinary levels can enable point‐of‐care testing for neuroendocrine tumors. A novel sensing electrodes array modified with biopolymer chitosan and electrocatalytic...
