Abstract
A novel inclusion complexes nanofibrous membrane fluorescent sensor was prepared for recognizing F- via electrospinning and host–guest interaction. The host α-cyclodextrin on the surface of the electrospun nanofiber membrane is assembled into the guest azobenzene molecule which modified with F- fluorescent probe, and the formation of the inclusion complex is fixed on the surface of the nanofibrous membrane without external force, to prepare a novel surface controllable composite nanofiber membrane for F- detection. The inclusion complexes nanofibrous membrane exhibited favourable sensitivity and selectivity for F-. The introduction of F- would result in notable fluorescent decreasing of the membrane, but the other most common anions would not disturb the detection of F-. Moreover, this nanofibrous membrane was not only a fluorescent sensor for detecting F-, but also a good adsorbent for F- in solution.
Highlights
F- is a very common anion in the environment, it always exists in the form of various compounds

The adsorption of F- in the human body is mainly in water,food and skin, the soluble F- in drinking water is almost absorbed by the small intestine and stomach, and the absorption rate of F- in food is about 50%, F- can be absorbed in human body by skin and transported to bone through blood [3, 4]
Summary
F- is a very common anion in the environment, it always exists in the form of various compounds. The F- content in human body is about 2.6 g, and 95% of them are distributed in bones and teeth to enhance their structure stability, in the second distributed in hair and nails,and microscale in organs [2]. Excessive F- in the human body will disturb the metabolism of calcium and phosphorus, damage to skeleton, cardiovascular and nervous system, and even result in pharyngitis, laryngitis, tracheitis, autonomic nerve dysfunction and acid erosion [5]. It is vital important to develop chemosensors for F- in the current environment
