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.
