Impact of nanotechnology

Nanotechnology is a field of research and innovation concerned with building 'things' - generally, materials and devices - on the scale of atoms and molecules. A nanometer is one-billionth of a meter: a sheet of paper is about 100,000 nanometers thick. Nanoscale particles are not new in either nature or science. However, the recent leaps in areas such as microscopy have given scientists new tools to understand and take advantage of phenomena that occur naturally when matter is organized at the nanoscale. In addition, scientists are developing the ability to manipulate atoms and molecules directly to create nanoscale devices. This article will discuss the impact of nanotechnology on various fields, particularly in medicine.

Impact on Medicine[edit | edit source]

Nanotechnology has the potential to revolutionize the field of medicine. It can provide solutions at the cellular and molecular levels, which can potentially cure diseases and repair damaged tissues. Nanotechnology in medicine involves applications of nanoparticles currently under development, as well as longer range research that involves the use of manufactured nano-robots to make repairs at the cellular level.

Nanomedicine[edit | edit source]

Nanomedicine is a branch of medicine that applies the knowledge and tools of nanotechnology to the prevention and treatment of disease. It involves the use of nanoscale materials, such as biocompatible nanoparticles and nanorobots, for diagnosis, delivery, sensing or actuation purposes in a living organism.

Nanomedicine has the potential to develop radical new therapies based on an unprecedented control over both intracellular processes and the extracellular environment at the nanometer scale. Nanomedicine is a large industry, with nanomedicine sales reaching $16 billion in 2015, and with over 200 companies and 38 products worldwide, a minimum of $3.8 billion in nanotechnology R&D is being invested every year.

Drug Delivery[edit | edit source]

One application of nanotechnology in medicine currently being developed involves employing nanoparticles to deliver drugs, heat, light or other substances to specific types of cells (such as cancer cells). This technique reduces damage to healthy cells in the body and allows for earlier detection of disease.

Impact on Other Fields[edit | edit source]

Nanotechnology is not only revolutionizing the medical field, but it also has a significant impact on other areas such as material science, physics, chemistry, and engineering. It has the potential to bring about significant changes in the manufacturing sector, environmental conservation, energy sector, and information technology.

Conclusion[edit | edit source]

The impact of nanotechnology is vast and varied. It has the potential to bring about significant changes in many fields, particularly in medicine. However, as with any new technology, it also brings with it potential risks and challenges that need to be addressed. As we continue to explore the world at the nanoscale, it is important to consider both the benefits and the potential drawbacks of this exciting new technology.
