Abstract: Nano Science/Technology is a cutting edge technology of the present age but without the help of supporting technologies like proper imaging of nano structures or an ability of manipulation at atomic levels or to characterize them, it may not be possible to avail all the benefits of such a promising technology. The core objective of this talk will be to discuss the research activities; I have been involved during last two decades, which directly or indirectly supports nanoscience and nanotechnology, by discussing a realistic daily life application example. Two main streams (Applied superconductivity and solid‐ state magnetic sensors) will be discussed during the course of this seminar. Applied superconductivity with all its inherited remarkable properties direct our attention to use superconducting technology as future choice of technology to secure the quality of living by decreasing the expense and providing speed and reliability. On the other hand, field of Semiconductor is well established but new applications are being discovered every day and there is lots of room for making improvements in the existing technology. There is lot of room for new generation scientist/engineers to come forward and bring forth what has not been understood (theoretically) and is not discovered (experimentally) yet, related to both technologies. Starting with a brief overview of the basic requirements for a given daily life technological problem, detail break down of the technology requirement and worked out solutions will be discussed with brief introduction to relating technology. In the field of applied superconductivity, we will briefly explain “Infrared Bolometer Detectors” for detection of infrared signals, “Josephson Junctions” as a building block of superconducting electronics and “Superconducting Quantum Interference Devices (SQUID)” the world most sensitive magnetic sensors with sensitivity down to fT range. Beside this, a research highlight related to “Variable Temperature Scanning Probe Microscopy” an eye and hand in the world of nano, and “non‐destructive evaluation systems” for medical diagnosis and industrial solution of product characterization, will also be presented. In the third part of the presentation, a glimpse of future research possibilities will be presented.
