Nanotechnology opens up employment opportunities in various industries

The word “nano” refers to the length scale (a nanometer is one billionth of a meter) which is a thousand times smaller than the micro scale, the scale traditionally associated with the electronics industry. Viruses and DNA are examples of natural objects at the nanoscale; on the other hand, a human cell can appear enormous.

The term nanotechnology refers to the engineering, measurement, and understanding of materials and devices at the nanoscale. Manipulating matter atom by atom and creating characteristics at the atomic or “nano” scale is now a proven technology and there is an ever-growing catalog that uses nanotechnology.

Nanotechnology is a whole scientific and technical field, largely within materials science and engineering, and not just a single product or even a group of products. As a result, there are many different types of nanotechnology and many applications associated with each type. There are also several other types of nanoscale objects that exist in our environment, both natural and unnatural, such as films and coatings, embedded nanotechnologies, biologically natural, biological nanotechnologies, natural particles, manufactured particles. , nano-electrical mechanical systems.

Building on current applications of nanotechnology in fields as diverse as consumer electronics, medicine, energy, water purification, aerospace, automotive, infrastructure, sporting goods , textiles and agriculture, nanotechnology research underway today will enable entirely new capabilities and products. Nanotechnology is also the basis of the key industries of the future. For example, new architectures and paradigms harnessing nanotechnology are laying the groundwork for artificial intelligence (AI), quantum information science (QIS), next-generation wireless communications, and advanced manufacturing .

While advances in modern electronics have long been at the nanoscale, new nanomaterials and designs will ensure the continued strength of the semiconductor industry, which powers computing, e-commerce and national security. . Nanotechnology also enables the rapid genomic sequencing and detection needed to advance medicine and biotechnology. Nanotechnology R&D has enabled early detection of emerging diseases and will lead to treatments of the future. Past investments in nanotechnology research and development have provided a basis to support the response to the Covid-19 pandemic. Nanotechnology-based applications include vaccines, sensors, masks, filters, and antimicrobial coatings.

Examples of nanotechnology innovations are: a highly sensitive portable gas sensor; nanoparticles taken up by plants to provide nutrients; durable, conductive wires made with MXene; electrodes which incorporate nanoparticles and allow the conversion of sunlight into hydrogen fuel; nano-designed pores in a membrane for water filtration; drug-laden nanoparticles carried by red blood cells; and the world’s first programmable memristor computer, enabling low power AI applications. Advances in nanotechnology are impacting a variety of other sectors, including consumer electronics, aerospace, automotive, infrastructure, sporting goods, and agriculture.

Research infrastructures

Research infrastructure, including physical and cybernetic resources as well as education and workforce development efforts, is critical to supporting the entire funding ecosystem (National Nanotechnology Initiative ), and agencies will continue to invest in these important areas. Agencies use a wide variety of mechanisms to support research infrastructure, including Center grants, instrument development or acquisition programs, training grants, fellowships, and collaborative programs that support research. workforce development.
