[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Fluorescent sensors are very useful tools for exploring chemical biology and advanced medical research. Herein, we propose four different fluorescent sensor systems for the recognition of some important biological molecules. The first sensor system is a multi-component fluorescent sensor complex for the sensing of glycolipids. The glycolipid sensor system is a novel design that takes advantage of supramolecular self-assembly. Results show that it can bind with both the sugar headgroup and hydrocarbon tail of glycolipids, and turn on the fluorescence of the sensor system. The second sensor is a cell-impermeable fluorescent sensor system for the recognition and extraction of glycolipids from vesicles. To avoid the fluorescence enhancement caused by the hydrophobic effect from cell membrane, we designed a series of cell-impermeable sensor complexes. In addition, these complexes were fully explored by vesicle studies. Another fluorescent sensor is NS600 which was developed for detecting and imaging glutamate in neurons. This sensor system that utilizes a nucleophilic aromatic substitution for glutamate binding, and produces a 270-fold fluorescence enchantment upon glutamate binding. Also, it overcomes drawbacks of previous glutamate sensors including low signal response and poor sensitivity. It enables a clear and accurate visualization of glutamate in cultural neurons. The last sensor is NS570, a cell-impermeable glutamate sensor which could be loaded into synaptic vesicles by vesicle cycling. This sensor is a reversible chemical sensor that gives a 2600-fold fluorescence enhancement upon the titration with glutamate and can be used to monitor the release of neuronal glutamate in real time.

Rutin (R), a representative flavonoid found in various biomasses, can be used to prepare different fluorescent sensors for environmental, biological and medical fields. In this work, the natural R in Sophora japonica was extracted and purified to prepare fluorescent-responding sensor systems intended to recognize copper ions with both strong selectivity as well as appropriate sensitivity. Results showed that neat R had no obvious fluorescent emission peak in PBS buffer solution. However, when R and (2-hydroxypropyl)-β-cyclodextrin (CD) were introduced within buffer solution, fluorescent emission intensity was significantly increased due to the resultant R-CD inclusion complex. In addition, the formed R-CD inclusion complex was shown to behave as the aforementioned fluorescent sensor for copper ions through a mechanism of quenched fluorescent emission intensity when R-CD became bound with copper ions. The binding constant value for R-CD with copper ions was 1.33 × 106, allowing for quantification of copper ions between the concentration range of 1.0 × 10–7–4.2 × 10–6mol⋅L–1. Furthermore, the minimum detection limit was found to be 3.5 × 10–8mol⋅L–1. This work showed the prepared R-CD inclusion complex was both highly selective and strongly sensitive toward copper ions, indicating that this system could be applied into various fields where copper ions are of concern.
