Nano chemistry is a fascinating branch of chemistry that focuses on the study, manipulation, and application of materials at the nanoscale, typically within the range of 1 to 100 nanometers. At this scale, materials exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts [1]. Nano chemistry plays a pivotal role in various industries, including medicine, energy, electronics, and environmental science [2]. Nanochemistry is a groundbreaking field at the intersection of chemistry, physics, and materials science that deals with the manipulation and synthesis of materials at the nanometer scale. The word 'nano' originates from the Greek term 'nanos,' meaning 'dwarf,' and refers to structures ranging from 1 to 100 nanometers in size [3]. At this scale, materials exhibit unique and often unpredictable properties that differ significantly from their bulk counterparts. These nanoscale properties enable a wide range of applications, from medicine and electronics to energy storage and environmental remediation [4]. The rise of nanochemistry has been fueled by advancements in nanotechnology, allowing scientists to engineer molecular structures with precision. Unlike traditional chemistry, which typically deals with macroscopic substances, nanochemistry focuses on individual atoms and molecules, tailoring them for specific functionalities [5]. One of the core principles behind this field is the size-dependent behavior of nanoparticles, which results in altered optical, electrical, and chemical characteristics [6]. This opens the door to revolutionary breakthroughs, including targeted drug delivery, nanosensors, and self-cleaning materials. The applications of nanochemistry are vast and continue to expand with ongoing research. In medicine, nanoparticles are used for drug delivery, imaging, and early disease detection [7]. In the energy sector, nanomaterials enhance the efficiency of solar cells and batteries. Meanwhile, industries ranging from textiles to environmental science benefit from nanoscale coatings and catalysts that improve durability and reduce waste. With its multidisciplinary nature, nanochemistry is at the forefront of scientific innovation, offering sustainable solutions to modern challenges [8].

This paper explores the fundamental principles of nanochemistry, the methods used for nanoscale synthesis, and the wide-ranging applications that have emerged from this dynamic field. By delving into these topics, we aim to provide a comprehensive understanding of how nanochemistry is shaping the future of science and technology.
