Comparative Materials-Level Evaluation of 3′- and 5′-Thiol DNA Aptamer Conjugation on Gold Nanospheres and Nanoflowers: Apparent DNA Loading Output, Morphology Retention, and Qualitative Salt-Challenge Response

Gold nanospheres (AuNPs) and gold nanoflowers (AuNFs) are widely used as platforms for DNA aptamer functionalization, while conjugation behavior and colloidal tolerance remain important factors affecting subsequent sensing-oriented optimization. In this study, 82-nt thiolated DNA aptamer constructs...
