Total surface area is the amount of two-dimensional space occupied by a given object. It is the result of multiplying two length measurements together, which is represented as a number squared, for example 100 meters^2.

The general formula for the total surface area of a right prism is T. S. A. =ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.

Surface Area Formulas:

The surface area of a solid object is a measure of the total area that the surface of the object occupies. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces.

The surface area of a three-dimensional object is the total area of all of its surfaces. Surface area is important to know situations where we want to wrap something, paint something, and eventually while building things to get the best possible design.

Synthetic materials set new world record for greatest amount of surface area. Researchers at Northwestern University, Illinois, have broken a world record in the creation of two synthetic materials, named NU-109 and NU-110, which have the greatest amount of surface areas of any material to date.

It means that the surface area to volume ratio increases as the radius of the sphere decreases and vice versa. Therefore, materials made of nanoparticles have a much greater surface area per unit volume ratio compared with the materials made up of bigger particles.

Depending on the particle shape, the European Commission has communicated nanomaterial identification guidelines that a material potentially composed of nanoparticles and with a volume specific surface area in the range of VSSA > 20 m2/m3 up to VSSA > 60 m2/m3 is entitled as a nanomaterial.

Because surface area is the means by which a solid interacts with its surroundings, be it gas, liquid or other solids. As particle size decreases, the surface area per unit volume (or mass) increases.

Nanoscale materials have far larger surface areas than similar masses of larger-scale materials. As surface area per mass of a material increases, a greater amount of the material can come into contact with surrounding materials, thus affecting reactivity.

The nanoscale is the dimensional range of approximately 1 to 100 nanometres. But what does this really mean? To begin, take a look at the back of your hand. Using just your eyes you can focus down to a scale of 1 centimetre to 1 millimetre.

Thus, constructions made from DNA will have nanoscale features. We are all aware that the DNA found in cells is a double helix consisting of two antiparallel strands held together by specific hydrogen-bonded base pairs; adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).

Nanotechnology increases the strengths of many materials and devices, as well as enhances efficiencies of monitoring devices, remediation of environmental pollution, and renewable energy production. Choosing right, less toxic materials (e.g., graphene) will make huge impacts on the environment.

The creation of xenobots is groundbreaking. Despite being described as “programmable living robots”, they are actually completely organic and made of living tissue.

Having this massive knowledge, nanotechnology can be used in neural tissue growth, also adapts devices for interference of neural networks. Especially Nano medicine where technique is involved and the role function in which these Nano particles apply to central nervous system (CNS) and imaging of CNS.
