Dopamine plays an important function in the neurological system, and its detection sweat has received interest due to noninvasive nature. However, low concentration of dopamine hampered development current wearable sensors. To address this issue, we devised a novel approach based on nickel-platinum double-atom catalysts (Ni/Pt DACs), which exhibit exceptional oxidation properties. This extends range (10 nM 750 μM) reduces limit 5.48 nM, covering physiological concentrations human sweat. Experimental results density functional theory (DFT) simulations show that doping with platinum single atoms lowers activation energy reaction rate-determining step (RDS), increasing catalytic efficiency Ni/Pt DACs for dopamine. Furthermore, using hydrophilicity-modified four-inlet microfluidic device volunteer skin, were able measure real time cellphones. We also conducted preliminary investigation into application potential flexible zinc-air batteries (ZABs), including DFT theoretical analysis. discovery not only increases technology sweat, but sheds fresh light use diatomic batteries.

Dual-atom catalysts (DACs) have gained great attention as highly efficient materials for the hydrogen evolution reaction (HER) due to their synergistic dual-site effects and high atomic utilization. This review explores how microenvironmental regulation, including electronic structure optimization coordination design, influences DAC performance. Both homonuclear heteronuclear types of DACs are analyzed in detail terms site interactions structural configurations. Moreover, recent advancements HER applications under various pH conditions discussed, highlighting enhanced catalytic activity mechanism. Despite challenges synthesis characterization, represent a promising frontier developing offer guidance future research scalable applications.
