We evaluated the stability of the mpGNS-3@ab probe by examining its morphology after six months of storage in a standard refrigerator at 2-8 ºC. Furthermore, we compared the performance of our mpLFIA with previously reported colorimetric sensing approaches that utilize magneto-plasmonics nanoparticle systems (Table ). The results demonstrate that mpGNS-3 achieves the highest colorimetric efficiency and significantly improved LFIA sensitivity compared to existing colorimetric LFIA probes. By integrating magnetic concentration of larger sample volumes with plasmonic enhancement-enabled by the gold nanostar shell coating, the magnetic core-mpGNS-3 surpasses traditional LFIA approaches based on gold nanospheres and other nanoparticle systems. Ultimately, these findings confirm that the mpGNS-3 probe offers superior colorimetric enhancement, excellent antibody conjugation efficiency, and long-term stability, making it a highly effective tool for sensitive LFIA detection.
