Nanoscience is concerned with the study of the chemical and physical properties of materials at the scale of 1 to 100 nanometer (nm). Nanometer is a billionth of a meter and materials at a scale of 1 to 100nm are called nanostructures.
Nanotechnology is concerned with the development of new, useful products or methods through manipulation of material at the scale of 1 to 100nm. This may involve turning nanomaterial into useable tools and applications.
The future of Nanoscience and Nanotechnology may entail enhanced and high level collaboration among physicists, biologists, chemists and technologists to transform operations by making a diverse range of materials and devices on the scale of a nanometer. What this future portends is uncharted but worth speculating. The impact of Nanoscience and Nanotechnology possesses the potential and power to revolutionize the world if we follow the emerging trends. However, this future will be determined by the nanoscientists and nanotechnologists and how people embrace it.
Although some trends have begun with thermal devices used in medicine, the future portends a revolution in nanosurgery where molecular reconstruction could instil life in materials. It could improve, prevent and treat serious injuries and diseases by sensing and identifying, removing and repairing cancer cells and even implanting healthy cells.
Medicine will advance to such a level that injectable nanomaterial could be introduced into the human body to reverse natural aging, cure diabetes, grow spurs and manage HIV and AIDs, and even make human life immortal. However, if people become immortal, overpopulation will make existence unbearable.
Nano-devices would develop robots to perform human tasks, applications that enhance displays and resolution, reduce pollution and improve sensing.
Technology makes things which seemed impossible before their arrival, however caution needs to be taken since machines may replace the need of human interventions in many fields.
