“…However, possibilities of a tube wall modification performed by conventional methods, such as synthesis from the gas phase, sputtering, wet deposition, and other, are limited by the restricted access to the tube interior. The rolled-up technology provides more opportunities for the design of tube surfaces if the planar surface is modified before twisting . In the present work, we suggest using the successive ionic layer deposition (SILD) to modify the surface of iron oxide microtubes by silver nanoparticles (Ag NPs). , SILD technology belongs to an extensive group of layer-by-layer synthesis (LbL) techniques .…”
