Novel near infrared-absorbing iron oxide-gold core-shell nanoparticles in pin shapes were synthesized. The nanopins are superparamagnetic, with 35-fold better surface enhanced Raman scattering activities than the conventional core-shell nanospheres and 50-fold greater photothermal properties than solid gold nanorods. The nanoparticles will have important impact on medical imaging, molecular diagnostics and disease treatment.
新型近红外吸收氧化铁-金核壳纳米针被成功合成。这些纳米针具有超顺磁性，比传统核壳纳米球的表面增强拉曼散射活性高 35 倍，比实心金纳米棒的光热性能高 50 倍。这些纳米颗粒将对医学成像、分子诊断和疾病治疗产生重要影响。
