Covering the theory, design, and fabrication of nanostructured superconducting materials, this monograph serves as a vital resource for research and development in various fields, including energy-saving solutions, healthcare, and communication technologies. It emphasizes the role of nanopatterned materials in enhancing superconducting critical parameters and device performance, leading to innovative functionalities. The contents include a tutorial on nanostructured superconductors, imaging techniques for vortices from atomic to macroscopic scales, and probing vortex dynamics at the single vortex level using scanning ac-susceptibility microscopy. It also discusses STM studies of vortex cores in strongly confined nanoscale superconductors, Type-1.5 superconductivity, and direct visualization of vortex patterns influenced by competing interactions. Further topics cover vortex dynamics in nanofabricated high-temperature superconducting films, artificial pinning sites, and their applications, as well as vortices at microwave frequencies. The physics and operation of superconducting single-photon devices, the Josephson and charging effects in mesoscopic devices, and recent advances in NanoSQUIDs are also explored. Additionally, the text addresses Bi2Sr2CaCu2O8 intrinsic Josephson junction stacks as terahertz radiation emitters, interference phenomena in superconductor-ferromagnet hybrids, and the dynamics of spin-orbit interact
