Real-time tracking and bio-imaging of cancer cells based on novel nanoscaled probes
State Key Laboratory of Bioelectronics, Southeast University, China
The early efficient diagnosis and therapy of some important disease like cancers is still a hot topic in the relative areas involving in patient care and treatments. The multidrug resistance (MDR) is often one of the major obstacles in relevant therapies due to disease-causing organisms to withstand a wide variety of structurally and functionally distinct drugs or chemicals. Diagnosis and therapy in combination with nanotechnology may offer an alternative promising and overcome the difficulty. And the early diagnosis based on some smart supramolecules and nano-biotechnology could be crucial for a successful treatment of cancers.
This study has established some ultrasensitive and intelligently supramolecules and multi-functional nanoprobes as well as multi-mode imaging techniques for real-time dynamic analysis of biomolecules/ cells/tissues. Meanwhile, we have developed a new strategy for the fast and high sensitive recognition of the target biomolecules and cancer cells by combining the supramolecular probes and functionalized nano-interface with the spectra-electrochemical study. Especially, the ultrasensitive in vivo bio-imaging of cancer cells and diseased tissues has been realized through in situ biosynthesized near-infrared fluorescence nanoclusters, establishing creative methods for non-invasive molecular diagnosis and treatment of some difficult diseases like cancers, thus paving the novel path for cancer diagnosis and treatment.
