Structures and mechanisms involved in RNA processing and transport
Prof. Meng Li（Department of Environmental Science and Engineering, North China Electric Power University）
Over several decades, fluorescence-based sensors have been extensively investigated owing to their high sensitivity and selectivity and the potential for rapid real-time monitoring of many analytes, including metal ions, nitrites, amino acids, and proteins, etc. With the development of sensing technology, conventional solution-based sensing has gradually shown limitations in real applications. In comparison, solid-state sensor materials have some preferred advantages such as portability, operational simplicity, and reusability, which make rapid online detection possible at a low cost. These materials-based probes may be ultimately employed for basic laboratory assays as portable measurement devices and for household use as commercial indictors. Therefore, the quest for ecofriendly materials-based sensors with simple and smart detection is of exceptional importance. Recently, intensive research has been devoted to the development of robust and highly selective and sensitive agents as replacements for conventional sensing molecules. In this regard, cellulose materials such as membranes, nanofibers, and nanocrystals serve as attractive probe candidates. Therefore, cellulose-based materials functionalized with fluorescence sensors are highly topical and are employed in many areas of functional materials, including the sensing of heavy-metal ions and anions as well as being widely used as chemical sensors and tools for environmental applications.
