G-四链体DNA在基因中广泛存在,并参与基因调控和端粒长度保持等重要生理功能。此外,G-四链体作为基本结构单元被广泛用于构建DNA酶、生物传感器、适配体和新型生物药物。因此研究G-四链体DNA结构对理解其体内和体外功能尤为重要。本工作发现,在特定溶液中,除了已知的G-tracts的长度、flanking序列、loop长度和碱基组成外,DNA G-四链体折叠结构还由不同长度loop的组合排列决定(见
随着社会发展，食品安全问题日益受到重视。霉菌毒素作为次级代谢物，是由丝状真菌产生的一类天然小分子，对人和动物的健康有严重的危害，是食品安全问题监测的主要对象之一[1]。因此，建立高灵敏、低成本、高识别性和快速可靠检测霉菌毒素的技术，减少霉菌毒素危害具有重要的意义[2]。
恶性肿瘤的早期诊断与治疗对于病灶治愈、患者康复起着关键作用。如何在细胞与分子水平上实现肿瘤的早期监测，并在此基础上开发可用于光热治疗、声学空化治疗、化药协同治疗等诊疗一体化材料以实现对疾病的精确、便捷的影像辅助诊疗，这一策略的实现有赖于功能微纳分子探针的发展。

对于蛋白质的可逆氧化的细胞信号转导，过氧化氢在其中起着很重要的作用[1]。我们设计了一个新型萘酰亚胺类荧光探针 Mito-NH 用于检测线粒体中的过氧化氢，该探针是基于光诱导电子策略并利用苯偶酰基团作为猝灭荧光基团以及识别基团。在过氧化氢的存在下，苯偶酰基团转化为苯甲酸酐，随后苯甲酸酐水解得到苯甲酸。这类荧光探针 Mito-NH 灵敏度高，选择性好，极具实用价值。
为了提高生物分子检测的灵敏度和选择性,生物传感器被设计得越来越复杂。那么,构建方法简单同时又具有高灵敏度和选择性的生物分子检测器成为现在研究领域的一个巨大的挑战。本文提出了一种具有自清洁性能和识别生物分子功能的光电化学(PEC)传感器,其中以TiO2纳米管光子晶体(TiO2,NTPCs)材料作为光电极,多巴胺(DA)分子作为敏化剂和靶分析物。
