Summary: In this study, electrochemical dopamine sensors based on reduced graphene oxide coupled with Au or Pt nanoparticles were developed and showed high sensitivity in detecting dopamine in synthetic urine. The sensors exhibited negligible interference from uric and ascorbic acids, and achieved a wide linear range and low limit of detection for both Au and Pt nanoparticles. Real urine samples also showed closely aligned dopamine concentrations with measurements from conventional laboratory techniques. The sensor fabrication process was cost-effective and had the potential for integration into flexible substrates, allowing for the development of wearable sensing devices.

Summary: A rapid and straightforward electrochemical sensor was developed for the detection of Cu2O nanoparticles under neutral conditions using a semipermeable Nafion membrane. The sensor overcomes the challenges of quantitative and on-site analysis of Cu2O nanoparticles at ultra-low concentrations. The enhanced electroreduction of Cu2O nanoparticles is achieved through improved neutralization of generated OH. ions facilitated by Nafion. The sensor exhibits a linear detection range of 0.00-0.20 μg and 0.20-2.0 μg of Cu2O, with sensitivities of 107 ± 3 μA μg-1 and 23 ± 3 μA μg-1, respectively. The detection limit (3SB/m) is 0.23 ng. The sensor demonstrates good reproducibility with a relative standard deviation below 5% and is effective in detecting Cu2O nanoparticles in various water samples.
