Recent studies on the growth of semiconductor and ceramic nanostructures ranging from 1D arrays to 3D networks, have attracted immense research motivation due to their multi-functional properties which offer a huge amount of applications like nanoelectronics, sensors and mainly biological engineering. However mass scale synthesis of nanostructures or synthesis of hyperbranched interconnected extremely large networked nanostructures is still an open challenge. The vapour liquid solid (VLS) process is the most used technique but according to the recent demands in nanotechnology the VLS process needed further simplification or development of new techniques. The present work demonstrates a very simple flame transport synthesis (FTS) approach which offers synthesis of desired semiconductor and ceramic nanostructures. A complete overview of the family of ZnO nano-micro structures along with the glimpses of SnO2, Fe2O3, Bi2O3 and Al2O3 nanostructures synthesized by FTS approach will be presented and the role of different growth parameters will be discussed. Preliminary results of the corresponding current-voltage response, elastic modulus as well as possible applications in biomedical engineering will be presented.
