Abstract: The design of high-performance electrochemical sensor and biosensor platforms has
attracted much interest for the sensitive and selective detection of emergent biomarkers. The electrochemical
sensor offers numerous advantageous features including cost-effectiveness and ease of
miniaturization, rapid and online monitoring, simultaneous detection ability, etc., which have captivated
the potential interdisciplinary research. In this review, the advances and challenges towards
the electrochemical detection of emergent biomarkers such as hydrogen peroxide, nitric oxide, β-
nicotinamide adenine acetaminophen, dinucleotide (NADH) in biofluids are highlighted based on
the recent research outcomes. In fact, the effective utility and benefits of transition metal nanocomposites
without the utilization of biological materials, including enzymes, antibodies, etc., as electrode
materials towards the detection of selected biomarkers in practical biofluids, monitoring
early-stage and diagnosis of disease related biomarkers, are also described. These promising metal
nanomaterials based electrochemical sensor platforms concrete the tactic for a new generation of
sensing devices.
