We report a new method to precisely locate inorganic nanoparticles at polymeric fiber crossing sites. Polymeric fibers are aligned by a previously reported non-electrospinning Spinneret based Tunable Engineered Parameters (STEP) polymeric fiber manufac- turing technique. Cross-hatch pattern (perpendicular) of polymeric fibers embedded with inorganic nanoparticles (e.g.: Fe(NO₃)₃ or Bi(NO₃)₃) were fabricated on top of each other and the fiber compositions re-acted during annealing process, thus, producing a desired phase (e.g.: BiFeO₃) only at the crossing site. Our method of-fers an easy way to mass arrange and locate nanoparticles at designed positions on virtually all types of substrates.
