Abstract： In recent years，advancements inthe preparation and concealmentof explosives have presented increasinglysignificantchallengesfortheirdetection.Organicsmal-moleculefluorescentprobeswithhighsensitivity，highselectivityandlowdetectionlimithavebecomewidelyused inexplosiveidentification.However，theidentificationof explosivesbythesefluorescentprobesoftenneedstobecariedoutinsolution，resultinginasignificantlimitationof theirapplication.Electrospining representsahighly efective techniqueforthe fabricationof nanofibers characterized bycontrollable diameters and uniform morphologies.Fluorescent nanofiber membranes withtheadvantages of easy portability，goodreproducibilityand low detection limit were prepared by combining fluorescent probes with electrospinning technology，whichefectivelybroadened theapplicationoffluorescentprobesinthedetectionofexplosives.Inthis paper，the structure offluorescence sensing unitsoforganic small molecule materials is clasified，and theeffectsof organic smallmolecule fluorescent nanofiber membrane sensors on common explosives such as trinitrotoluene（TNT）， trinitrophenol（TNP），2，4-dinitrotoluene（DNT）and cyclotrimethylene trinitramine（RDX），triacetone triperoxide （TATP），etc.are summarized，give guidance for the design of electrospun fluorescent nanofiber membranes inactual explosives detection，and providenew ideas forthe practicalapplicationoffluorescentprobes incomplex environments.

1引言

爆炸恐怖襲擊事件嚴重威脅世界安全與社會穩(wěn)定，爆炸物的泄露還會對人類健康、生態(tài)環(huán)境造成直接危害，因此，爆炸物的檢測已成為當前國際安全中密切關(guān)注的問題之一[-3]。（剩余22966字）
