  本文通过苯并吲哚季铵盐与咔唑醛缩合制备了一种红色荧光的新型荧光探针。该荧光探针可以与HSO3-发生专一性地亲核加成反应来破坏分子内的共轭双键,导致探针溶液的颜色由红色变为无色,荧光由红色变为蓝色。该荧光探针具有水溶性好、与HSO3-定量反应、响应时间短、专一性强、检测限低(10 nM)等优点。

肿瘤标志物的发现是肿瘤研究和诊治的前沿方向。近年提出的利用肿瘤细胞筛选特异性核酸适配体,进而发现肿瘤标志物的方法具有好的应用前景。但目前只有极少数成功的例子,其中的瓶颈问题就在于位于细胞膜上的核酸适配体靶分子的纯化/鉴定。我们利用定量蛋白质组学的方法和手段,成功发展了一种可原位交联、可全程监控的通用型核酸适配体靶标鉴定方法。

本文介绍了一种新型的葡萄糖检测方法.采用聚乙二醇/葡聚糖双水相系统对单壁碳纳米管(SWCNTs)进行分离,通过调整表面活性剂、盐及酸的用量,使不同手性SWCNTs 在双水相两相中产生不同的分配,最终分离得到纯度较高的(6,5)SWCNTs.之后采用苯硼酸对SWNCTs 进行非共价修饰,将此复合物与葡萄糖进行特异性结合.
