Ultrasensitive Cell Recognition Based on Multifunctional Nanointerface Xuemei Wang1; 1SOUTHEAST UNIVERSITY, Nanjing, China; PAPER: 207/Electrochemistry/Regular (Oral) SCHEDULED: 16:45/Mon./Copacabana B (150/1st) ABSTRACT: The early diagnosis of important diseases, like cancer, is still a hot topic in the relative areas involved in patient care and treatments. In this study, we explored the possibility of applying a combination of molecular probes and nano-scaled materials in biomolecular recognition and high-sensitive detection of diseases like cancers. In particular, we have developed a new strategy for the fast and high sensitive recognition of target biomolecules and cancer cells, by combining some new ferrocene-substituted carborane derivatives and functionalized nano-interfaces with the spectro-electrochemical study. Our observations demonstrate that the self-assembly of the specific nanocomposites with the new molecular probes could provide a multifunctional interface for the rapid identification of cancer cells, with a broad detection range and low detection limit. It is evident that different types of cancer cells or bacteria could be readily distinguished on the relevant nanocomposites' modified nano-interface, which have the promising application to be adopted as a significant way to detect various kinds of mutant cells and advance the clinic diagnosis and treatment of target diseases. Moreover, some ultrasensitive and intelligently multi-functional nanoscale biomarkers, based on the <i>in vivo</i> bio-synthesized nanoclusters through utilizing the peculiarities of the redox homeostasis from cancer cells, have been also explored for the real-time monitoring and multimodality imaging of cancer cells / exosomes or target tissues.
