  • In the food area, researchers are working with nanotechnologies to create novel products that may be of benefit to health and diets. For example, nanosilver has antibacterial properties that can be used in food contact material such as cutting boards. In food supplements, nanosized carriers increase absorption of nutrients. Nanosensors can be incorporated into packaging to monitor the quality and shelf-life of food from manufacturers to consumers. It can also make food ingredients tastier or healthier.
  • When we say something is ‘Nano’, we mean it is very small. The size of one nanometer is a billionth of a meter, which is about 100,000 times as small as the width of a human hair. Making new things at this incredibly small scale is called ‘nanotechnology’ and it’s one of the most exciting and fast-moving areas of science today.
  • Nanotechnology is finding applications in plastics, paints and textiles. That has implications for automobiles as well. Nanoparticles are increasingly being used in the construction of modern automobiles. They help make car paint tougher and longer-lasting, improve the performance and efficiency of tires, or strengthen the adhesives used in some areas of car assembly. Experts say in the near future, most automobiles will be almost entirely held together with glues strengthened by nanoparticles.
  • 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 \(such as cancer cells\). Particles are engineered so that they are attracted to diseased cells, which allows direct treatment of those cells. This technique reduces damage to healthy cells in the body and allows for earlier detection of disease.
  • Those who become nanotechnologists typically have a keen interest in science and engineering. They must have excellent hand-eye coordination in order to work with specialized instrumentation and an excellent attitude towards working with other professionals in the field of nanotechnology. Nanotechnologists must also be extremely patient and persistent individuals, as the desired results of their work may not present themselves in a timely manner.
  • Nanoelectronics holds some answers for how we might increase the capabilities of electronics devices while we reduce their weight and power consumption. There are plenty of nanoelectronics areas under development such as improving display screens on electronics devices, increasing the density of memory chips and reducing the size of transistors used in integrated circuits.
  • Various manufacturers are using nanotechnology to make products with improved capabilities or to reduce their manufacturing cost.
    Researches at different Universities all over the world have developed such technics as laser shock imprinting, nanoscale diamond tips, semiconductor nanoparticles and many others.
