Prof. Satyabrata Jit of IIT BHU, Varanasi

Professor Satyabrata Jit delivered a series of insightful presentations, generously sharing their extensive expertise and research findings. The presentation delved into the origins of nanotechnology, tracing its roots back to seminal works by Richard Feynman and the inception of the concept of "nanotechnology" in 1959. Prof. Jit elaborated on the evolution of nanomaterials, emphasizing natural nanostructures like the Brazilian crystal, Lycurgus cup, cytomegalovirus, viral capsid, peacock wing, butterfly wings, and others, which paved the way for ground-breaking advancements in materials science and nanotechnology. The talk covered different types of nanomaterials commonly used in sensing applications, including nanoparticles, nanowires, nanotubes, and 2D materials like graphene. Each type of nanomaterial possesses distinct properties that can be tailored for specific sensing requirements. Building upon this historical foundation, the talk transitioned to an exploration of the unique properties of nanomaterials that make them highly suitable for sensing applications. Jit explained how the fundamental characteristics of nanomaterials, including their high surface-to-volume ratio, quantum effects, and tunable properties, confer exceptional sensitivity and selectivity in sensing devices. Furthermore, Prof. Jit discussed various synthesis methods for producing nanomaterials, such as chemical vapour deposition, sol-gel, and self-assembly techniques. Understanding these methods is crucial for controlling the size, morphology, and composition of nanomaterials, which directly influence their sensing performance. Throughout the presentation, examples of nanomaterial-based sensors for environmental monitoring, healthcare diagnostics, and food safety applications were discussed, illustrating the wide-ranging potential of nanotechnology in sensing. Finally, the discussion emphasized the relevance of nanomaterials in developing sensing technology, as well as continuing research efforts targeted at enhancing the performance and scalability of nanomaterial-based sensors.
