Shell-isolated nanoparticles (SHINs) with a 37 nm gold core and an 11 nm tin dioxide (SnO) coating exhibited long-life Raman enhancement for 3 months and a wide pH stability of pH 2-13 in comparison with conventional SiO-coated SHINs. Herein, Au-SnO is demonstrated as a more durable SHIN for use in the technique Shell-Isolated Nanoparticles for Enhanced Raman Spectroscopy (SHINERS).

具有37纳米金核和11纳米二氧化锡（SnO）涂层的壳层隔离纳米颗粒（SHINs），与传统的二氧化硅涂层SHINs相比，展现出长达3个月的长寿命拉曼增强效果以及pH值在2至13范围内的广泛pH稳定性。在此，金 - 二氧化锡被证明是一种更耐用的SHIN，可用于壳层隔离纳米颗粒增强拉曼光谱技术（SHINERS）。
