Summary: Copper pastes have attracted attention for their non-toxicity and cost-effectiveness. However, their long-term stability is challenging due to oxidation. Researchers have developed stable copper nanoparticles containing a Cu(0)-Cu(I) core-shell structure with a surface passivation layer. These copper pastes can be sintered in less than one minute, exhibiting high electrical conductivity, mechanical flexibility, and long-term stability comparable to silver pastes. They have potential applications in printed electronics, particularly in the fabrication of flexible devices.

Summary: Rapidly customizable and stable copper-nickel complex inks have been developed, which can transform into uniform copper-nickel core-shell nanostructures during low-temperature annealing and immediately sinter into copper-nickel alloy patterns under photon irradiation. The complex inks are particle-free, stable, and compatible with large-area screen printing. The printed copper-nickel alloy patterns exhibit high conductivity and oxidation resistance, and also maintain flexibility, making them suitable for additive manufacturing of highly reliable flexible electronics.

Summary: Electrochemical application has been widely used in biosensor research. In this study, a sensor electrode was improved to enhance the electrochemical conductivity for detecting small DNA molecule interactions. The electrode was modified with copper nanowires/gold nanoparticles, which were randomly distributed and compacted on the electrode surface, enhancing its electrochemical conductivity. The modified electrode exhibited efficient electrochemical conductivity of 20.3 mu A, with an increased effective surface area of 2.3-fold compared to the unmodified electrode, making it promising for biosensor applications.
