A solid-phase nano extraction device includes an extraction tube whose inner surface has a nanostructure for a large contact area with object to be detected. The nanostructure can adsorb objects in an extremely short reaction time. A driving structure is designed for the solid-phase micro extraction device. The extraction tube is connected to the driving structure for the objects to enter the fiber under the force of concentration gradient, pressure difference, or capillary force, thereby being adsorbed onto the nanostructure.

Methods of fabricating one-dimensional composite nanofiber on a template membrane with porous array by chemical or physical process are disclosed. The whole procedures are established under a base concept of 'secondary template'. First of all, tubular first nanofibers are grown up in the pores of the template membrane. Next, by using the hollow first nanofibers as the secondary templates, second nanofibers are produced therein. Finally, the template membrane is removed to obtain composite nanofibers. Showing superior performance in weight energy density, current discharge efficiency and irreversible capacity, the composite nanofibers are applied to extensive scopes like thin-film battery, hydrogen storage, molecular sieving, biosensor and catalyst support in addition to applications in lithium batteries.
