Abstract High‐entropy alloys (HEAs) have garnered extensive attention owing to their broad compositional tunability and high catalytic activity. However, precisely modulating the enzyme‐like activity of HEAs enhancing biocompatibility for biological applications remain severely challenging. Herein, PtRuFeCoNi HEA nanowires (NWs) are synthesized by adjusting metal composition surface‐engineered with polydopamine (PDA) form NWs@PDA nanozymes (HEzymes@PDA) superior photothermal properties. Density functional theory calculations Sabatier principle reveal that self‐polymerized PDA surface engineering moderately lowers d‐band center HEAs, optimizes charge distribution, enhances adsorption–desorption efficiency substrates. As a proof‐of‐concept, HEzymes@PDA synergistically integrated hydrogels biosensing analysis. This study presents an innovative paradigm designing highly active via demonstrates immense potential in sensing applications.
