The development of nanoclusters (NCs) capable multicolor emissions for simultaneous detection multiple analytes has aroused tremendous interest. However, the current methods synthesizing NCs with mainly depend on a ligand strategy, which not only compromises stability but also alters their physicochemical properties. Herein, we propose novel strategy designing single-ligand capped bimetallic Au/Os fluorescence by adjusting size NCs. This size-controlled, encapsulation enhances and compatibility ensures uniformity in properties, thereby overcoming limitations inherent multiligand systems. By meticulously modulating reaction parameters, achieved precise tuning size, resulting synthesis fluorescent displaying blue (465 nm), green (507 yellow (560 nm) emissions. These were then incorporated into an array system differentiation tetracyclines (TCs) virtue interaction TCs through inner filter effect (IFE). Finally, each TC elicited unique response, was subsequently analyzed principal component analysis. sensor been successfully employed milk, urine, water, demonstrating its practical application potential. developed this work holds great promise
