Characteristics of Nanotechnology

Naturally, nanotechnology is broad in size, including diverse scientific fields like molecular engineering, microfabrication, engineering, energy storage, semiconductor physics, molecular biology, organic chemistry, and surface science. There are equally diverse associated applications and researches, varying from the extensions of conventional device physics to the new approaches that are based on molecular self-assembly to develop the new materials with nanoscale dimensions for directing the matter’s control on the atomic scale.

The Future Implications of Nanotechnology

Nanotechnology's future implications are currently under debate by scientists. Nanotechnology can produce various new devices and materials with a broad number of applications, including consumer products, biomaterials energy production, nanoelectronics, and nanomedicine. Various similar issues have been raised by nanotechnology as any new technology, for instance, concerns about the nanomaterial's environmental impact and toxicity, and their possible effects on the global economics, along with the speculation about numerous scenarios. These concerns resulted in a debate among the governments on the warranty of nanotechnology's special regulation.

Fundamental Concepts

Engineering the functional systems at a molecular scale is known as nanotechnology. Both concepts and the current work are covered by these that are more advanced. Nanotechnology refers to the projected capability of constructing items from the bottom up, by utilizing tools and techniques that are being made today for making high-performance and complete products.

Scale Ranges

One is nanometer (nm) is 10-9 of a meter or one-billionth. The spacing between these atoms in a molecule or typical carbon-carbon bond lengths are in the 0.12-0.15 nm of range, and around 2 nm of diameter is possessed by a DNA double-helix. Whereas, the bacteria of the genus Mycoplasma, the smallest cellular life-forms are 200 nm in length. Following the definition that the National Technology Initiative in the US used, nanotechnology is taken as the scale range of 1-100 nm.

Upper and Lower Limits

The size of the atoms set the lower limit (the smallest atoms are possessed by hydrogen, which is almost a quarter of an nm kinetic diameter) as nanotechnology should make its devices from the molecules and atoms. The upper limit is more or less arbitrary and it is of usage in the nano device. Nanotechnology is made distinct by these new phenomena from devices that are rarely the miniaturized versions of an equivalent macroscopic device; these devices come under microtechnology and they come on a larger scale.

Nanometer’s Comparative Size

Nanometer's comparative size to a meter is similar to that of marble of the earth's size. A nanometer can be defined by the amount of beard that a normal nan grows from raising a razor to his face from the table.

Young et al. recently did a review on using plant viruses as the bio templates for the nanomaterials and their usages.

Nanotechnology in Food Packaging

There is a lead taken by the food industries in making good nutritive value food. For instance, they utilize high impermeable packaging nanomaterials to protect food from UV radiations and offer more strength for maintaining the protected food from the environment, thus improving and prolonging their shelf lives. Nanosensors are utilized to detect pathogens, gases, and chemicals, in food. Such type of packaging is often known as smart packaging in modern terminology. According to some of the studies, it is because of some of the risk factors that nanoparticles' direct involvement in food is not accepted by people. Thus, some safety measures should be provided for lessening human safety and risk.
