中文摘要：
生命科学扎基化学发展十分迅猛，化学对接生命科学应用前景宽阔。生命小分子乃至大分子DNA的识别与检测是当今世界科学研究一个重要方向。电化学传感是生物化学传感的一个主要领域，随着纳米技术的发展，稀土纳米材料及其掺杂复合材料用于生物电化学传感器制备、识别和实测异军突起。本项目以稀土纳米及其掺杂复合材料为基质，以电化学传感器为载体，以DNA及生物小分子为对象，开展了系列合成、制备、性能、识别、检测及规律的研究。先后合成16种稀土纳米材料（粒、棒、晶、簇）和稀土纳米复合材料；先后制备8种DNA电化学传感器，用于DNA的识别或A、G的检测，1种修饰电极用于尿嘧啶的检测，10余种生物、药物、环境小分子电化学传感器。先后建立了8种识别和检测DNA的新方法，10余种小分子电化学分析法。发表论文38篇（2006年11月前已接受而来不及注基金项目号的5篇），其中被SCI收录30篇，IF > 3.0 的论文10余篇。
