(a) Schematic drawings showing cross-sections of hollow nanofibers whose surfaces are derivatized with functional molecules (the top plate) and nanoparticles (NPs) (the other plates). (b,c) TEM images of hollow titania nanofibers immersed in an oil-based ferrofluid overnight. The hollow fibers are prepared by co-electrospinning, either with (b) or without (c) octadecyltrichlorosilane (OTS) added to the mineral oil. The interior of a hollow fiber is decorated by oil dispersible Au nanoparticles. Reprinted with permission from [149]. Copyright 2005 Wiley.
