1-dimensional nanomaterials which have the merits of large shape anisotropy and facile surface modification via binding of various chemicals and biological molecules, have drawn attention for their potential applications in biomedical sensors, energy storage, and magnetics. Among them, tubular and helical structures have recently received lots of attention due to their unique effects on the structural features instead of cylindrical shapes. For examples, nanotubes have an advantage over nanowires because of their larger specific surface areas including interior and exterior ones. On the other hands, helical nanosprings are promising among different systems, because of their additional advantage their motion can be controlled by magnetic field. As an example of application, under an external field, the helical NSs can be used as sensors, rotors and actuators. Furthermore, both of them have shown unique magnetic properties driven by their special shapes which are expected to create emerging concept of nanodevices such as nanorobots, nanomagnets, nanosensors, and magnetic memory. While the basic scientific knowledge and performance of applications have been greatly improved, there has been challenging to fabricate cheap, uniform and various materials of tubular and helical structures. In this dissertation, I introduce a facile synthesis method for modulating the morphology of Co based nanotubes and nanosprings prepared by template assisted electrodeposition without complication of conventional system for manufacturing nanowires. Co based nanotubes and nanosprings are synthesized by adding an additive with a concentration ratio of vanadyl ions (VO2+) divided by ascorbic acid to the existing metal precursor solution. Furthermore, I scrutinize the crystallization pathway of each shape in the spatially confined environment such as anodized aluminum oxide. To understand the formation mechanism, I confirm the chemical atmosphere and electronic flow on the surface of dielectric materials. Moreover, I utilize the non-classical crystallization models to explain their microstructural changes according to the various synthesis conditions.
