Nanotechnology: The branch of science and engineering that deals with designing, producing, and using structures, devices, and systems by altering atoms and molecules at the nanoscale is referred to as nanotechnology.<\/p>\n\n\n\n

Nanotechnology is used in various industries for technological advancements<\/a>. For example, it is currently used in the information and communications sectors, food industry, energy sectors, and in some medical products. In addition, nanomaterials offer methods for the reduction of environmental pollution.<\/p>\n\n\n\n

However,\nthere is a concern about nanomaterials. It is debated that these materials may\ncause threats to human health. Humans have created mechanisms of protection\nagainst several harmful agents. But, they had never been exposed to synthetic\nnanoparticles and their specific characteristics. Therefore the normal human\ndefense mechanisms associated with, for example, immune and inflammatory\nsystems may not be able to respond tolerably to these nanoparticles. In\naddition, there is also a threat that nanoparticles could disperse and persist\nin the environment, impacting the environment.<\/p>\n\n\n\n

There\nare different types of nanomaterials which are natural nanomaterials and\nartificial nanomaterials. Natural nanomaterials occur naturally in the world.\nThese include particles that form volcanic ash, smoke, and some molecules in\nour bodies, such as hemoglobin. Artificial nanomaterials occur from objects or\nprocesses created by people. Examples include exhaust from fossil fuel-burning\nengines and some forms of pollution. These are called intentionally produced\nnanomaterials.<\/p>\n\n\n\n

There\nare two ways to produce materials on the nanometer-scale, which are top-down or\nbottom-up. Top-down nanomanufacturing refers to carving bulk materials to make\nfeatures with nanometer-scale dimensions. Producers work to increase the\nefficiency of each “generation” of a microchip. Bottom-up\nnanomanufacturing creates products atom-by-atom. Using quantum dots and other\nnanomaterials, tech companies are now working to develop transistors and other\nelectronic devices using individual molecules. <\/p>\n\n\n\n

Many\nconsumer products already benefit from nanotechnology, such as clothes, food,\nelectronics, nanomedicine, etc. Nanotechnology is used to enhance clothing.\nManufacturers can make clothes that provide better protection from ultraviolet\nradiation. Some researchers are working with nanotechnology for “personal\nclimate control.” <\/p>\n\n\n\n

The\nfood industry is using nanomaterials in the packaging and agricultural sectors.\nFor instance, clay nanocomposites offer a strong barrier to gases in\nlightweight bottles, cartons, and packaging films. In addition, silver\nnanoparticles embedded in the plastic of storage containers kill bacteria.<\/p>\n\n\n\n

Nanotechnology has also transformed the realm of electronics. It offers quicker and more portable systems to manage and store larger amounts of data. Nanotech has even improved display screens on electronic devices. This involves reducing power consumption while decreasing the weight and thickness of the screens.<\/p>\n\n\n\n
