适配体修饰金硒纳米合金共振散射光谱法检测痕量Hg^2+被引量：3: 2011年; 用硼氢化钠还原法制备了金硒(AuSe)纳米合金。用单链核酸适配体(aptamer)修饰AuSe纳米合金制备了汞离子的核酸适配体纳米探针(Apta-AuSe)。在pH 6.8 Na2HPO4-NaH2PO4缓冲溶液中及NaCl存在下,Apta-AuSe纳米探针亦不聚集;当Hg2+存在时,它可以稳定aptamer序列中的T-T错配,形成较稳定的双链T-Hg2+-T错配物,从而使释放出来的AuSe纳米合金聚集形成较大的微粒,导致590 nm处共振散射峰增强。Hg2+浓度在1.3~1 466 nmol.L-1范围内与共振散射光强度呈良好线性关系,其回归方程和检出限分别为ΔI590 nm=0.603c+2.0和0.74 nmol.L-1。该方法用于水样中Hg2+的检测,结果满意。; 蒋治良张轶覃惠敏周莲平梁爱惠王鹏飞欧阳辉祥; 关键词：汞离子共振散射光谱法
