Abstract

Recent advances in nanotechnology have resulted in significant breakthroughs across several fields. Nobel laureate Richard Feynman introduced the concept of nanotechnology in his well-known presentation at the California Institute of Technology on December 29, 1959. In his paper, “There is plenty of room at the bottom,” he also covered the concept of nanoparticles. He emphasized that new physical and chemical features need to emerge from this nanoscale. Nanotechnology is a rapidly growing area of study that includes systems, gadgets, and structures with unique characteristics and capabilities because of the way their atoms are arranged on the 1–100 nm scale. This field could lead to significant changes in electronics, medicine, energy, and materials research. In this article, we aim to cover the history and recent advanced applications of nanotechnology, focusing on advancements in material science and technology that may occur in the future. Nanotechnology is evidently a very promising technology that has achieved significant advancements in a variety of disciplines, including environmental protection, medical, and energy equipment.

Introduction

Nanotechnology, the science and engineering of materials at the nanometer scale (1–100 nm), has emerged as a transformative field influencing nearly every aspect of modern life. The term “nano” comes from the Greek word for “dwarf” and refers to one-billionth of a meter [1]. By controlling matter at the atomic and molecular levels, scientists have unique physical, chemical, and biological properties that differ dramatically from those of bulk materials. Besides, at this scale, materials exhibit unique phenomena such as quantum effects, enhanced surface area-to-volume ratios, and altered optical, electrical, and mechanical characteristics. These improved properties have enabled the development of new technologies that are smaller, faster, and more efficient [2,3]. This review presents an in-depth analysis of nanotechnology’s historical evolution, its interdisciplinary advancements, and contemporary applications across various sectors, and its potential future directions. Moreover, this review article will cover the recent advanced applications of nanotechnology in different industries, mainly medicine, agriculture, food, cosmetics, automotive, chemical, and mechanical industries [4, 5].

Historical Advancements

The conceptual foundation of nanotechnology can be traced back to physicist Richard Feynman’s, who in 1959 presented his famous lecture “There’s Plenty of Room at the Bottom.” in which he envisioned the possibility of manipulating individual atoms and molecules to create smaller, more efficient systems [6,7]. However, it was not until the 1980s, with the invention of the Scanning Tunneling Microscope (STM) by Gerd Binnig and Heinrich Rohrer, that this vision became experimentally realizable [8,9]. This development marked the true beginning of modern nanotechnology, allowing scientists to visualize and manipulate materials at the atomic level. Subsequent discoveries, such as Fullerenes (C₆₀) in 1985 and Carbon Nanotubes in 1991, further expanded the field, introducing new classes of nanomaterials with exceptional mechanical, electrical, and thermal properties [10].

By the 21st century, nanotechnology has evolved from a purely scientific pursuit into a cornerstone of technological advancement and industrial application. It has transformed healthcare through targeted drug delivery systems and nanoscale diagnostics, revolutionized electronics through miniaturized components, and enhanced environmental sustainability by contributing to clean energy and pollution control technologies [11,12]. The global nanotechnology industry continues to grow rapidly, supported by national initiatives and increasing investment in research and development. Yet, alongside its tremendous potential, nanotechnology also poses challenges and ethical considerations, including concerns over nanoparticle toxicity, environmental safety, and equitable access to emerging technologies. Thus, the evolution of nanotechnology reflects not only a remarkable scientific journey but also an ongoing dialogue between innovation, responsibility, and societal impact.
