Tumor Diagnosis and Treatment Based on Stimuli‐Responsive Aggregation of Gold Nanoparticles

Gold nanomaterials have been used in the diagnosis and treatment of different tumors due to their unique physical and chemical properties. Among them, gold nanoparticles with stimuli-responsive aggregation functions have attracted extensive attention because they can meet the unique needs of tumor diagnosis and treatment at different stages through structural changes. However, how to effectively modify gold nanoparticles to achieve structural transformation for specific stimuli, and the role of corresponding structural transformation in improving the effect of diagnosis and treatment still lack systematic summary. In this review, we comprehensively summarized the current strategies for inducing gold nanoparticles aggregation and its advances in tumor diagnosis and treatment.
