As a new type of nanomaterial, DNA-templated silver nanoclusters (DNA-AgNCs) have been widely studied because their fluorescence and antibacterial properties. In this study, we combined the DNA-AgNCs with aptamers bacteria to achieve novel approach for visual detection effective elimination bacteria. The Staphylococcus aureus (S. aureus) were linked G-rich sequences enhancement when approaching DNA-AgNCs. capture not only realized monitoring but also promoted effects. Additionally,...

Abstract The valence‐electron arrangement of heterogeneous catalysts can significantly affect the binding behavior absorbates. However, it remains a challenge to understand role in electrocatalysis, which limits its utilization as tool design efficient electrocatalysts.
