DNA nanotechnology uses of DNA building blocks to develop new complex DNA structures with powerful characteristics. DNA is usually a straight and smooth molecule, whose total axis is unbranched. but DNA particles having junctions can also be created.For instance four armed strcuture junction can made further complementary moelcules. the basic purpose of this technology is to give a target structure and complex functional characteristics makes it different from other dominant technologies, it was designed ot determine the sequence of molecules and to discover their family.DNA nanotechnology detects the assembling sequence and then,collectively find out the junctions if any.after tracking the assembled sequence the kind of molecules rae comunicated to the other peripheral device,if attached. Different kind of approaches are used to design and manage the DNA sequences for obtaining the desired structure.

There are several approaches in which DNA strcutures can be designed some of them are listed below.

 Tile-based structural Approach

 Folding structural approach

 Kinetic assembling

 Sequence design

In these type of strucral approach the DNA molecules are designed in tiled architecture.The most common example of this appraoch is DX molecule in which two dimentional arrays are drawn at top and bottom in sequence of four tiles.Tile based approach is one of the earliest approach which was used to design the DNA structures every shape represents a sticky end for the next moelcule.Discrete units can be constrcucted with this method.This design method has a capability to concepulaize and design even the largest assemblies assigned to it.This distinguishing feature makes DNA nanotechnology fully benificial in the self assembly and computational functioning.

Another but opposite approach to tile based appraoch is folding approach.Arbitrary sequences and two dimentaional complex molecular arrangements can be converted into desired shape with the help of folding structural approach.simpler strands participates in folding strcutures.

Another useful approach to design the molecular structure regardless of the sequence and position is the kinectic assembly in which molecules are assembled with minimum thermodynamics sequence.DNA self assembly is one of the examples of this kind and is this method is widely used in therodynamic applications.

Another approach is sequnece design in which molecules are designed in a specific provided sequence to produce DNA design.Nuclear acids are the example of sequencial designing approach.

Using nanotechnology that might cure HIV comes in various forms. Most of these are still in the laboratory testing stages and are not yet available for mass treatment. Nonetheless, feedbacks have been very encouraging to the point that experts regularly call their efforts already a success even with the absence of actual testing on HIV patients. The following are some of the most common approaches in using nanotechnology that might cure HIV:

Neutralization of the HIV virus. Because HIV virus has been so resilient and tough to crack, one of the keys to a successful treatment of HIV cases is to neutralize the very virus that causes it. In this, scientists have developed nano particles that attack the virus. Because nano particles are very small, they are not easily detected and neutralized by the virus. Instead, they are able to penetrate the mantle of the virus, thus rendering it harmless.

Another approach in nanotechnology that might cure HIV is the strengthening of a person’s immune system. This is made possible with the use of nano particles that are injected into a person’s body. Such particles boost the immune system and help the body to repair damaged tissues, which is something very common among HIV patients. On the other hand, because they are very minute particles, they easily mix in with the bloodstream and distributed in the body.

Combination therapy is one of the techniques using nanotechnology that might cure HIV. In this, the therapy of attacking the HIV virus is paired with the strategy of enhancing the immune system. Because of this, patients who would have died from an HIV infection now have a better chance to survive the virus instead. Moreover, the immune system is boosted and rejuvenated, which not only improves the chances of a person surviving HIV but also a chance for a better health.

Despite the very promising and rosy picture all these products of nanotechnology that might cure HIV brings, the reality is that these are all still in the planning board. Scientists themselves acknowledge that plenty of researches have to be done before these treatments will be available on a mass basis.

Nanotechnology may be able to create many new materials and devices with several applications in energy production, medicine, organic materials and electronics.

Recently there has been many applications using nanotechnology also known as nanotech.

Carbon nanotubes, graphene and their compounds presents electrical properties for organic materials, and electronic applications such as photovoltaics, sensors, semiconductor devices, displays, conductors, smart textiles and energy conversion devices (e.g., fuel cells, harvesters and batteries).

Depending on their chemical structure, carbon nanotubes (CNTs) can be used as an alternative to organic or inorganic semiconductors as well as conductors. In addition to their high conductance, they can be transparent, flexible and even stretchable. Here, applications are for displays, replacing ITO; touch screens, photovoltaics and display bus bars and beyond. CNTs will be able to provide high performing devices which can ultimately be made in low cost manufacturing processes such as printing, over large areas. They have application to supercapacitors, which bridge the gap between batteries and capacitors, leveraging the energy density of batteries with the power density of capacitors and transistors.

Graphene, a cheap organic material, is to be used in some applications as a significantly cheaper printed conductor compared to silver ink. Graphene and its compounds are increasingly used to make transistors that show extremely good performance.

With their latest invention engineers will be able to make clothing that could power different portable devices. It is worth mentioning that thanks to nano-sized generators with piezoelectric properties the nanofibers have the ability to transform energy from mechanical stresses, stretches and twists into power. Thus, if used in clothing, the nanofibers could make use of body movements to power gadgets.

Nanoparticles are used by U.S. researchers to ‘smell’ the scent of illnesses in fluids of the body. The researchers used nanoparticles of gold with different coatings to distinguish among different proteins and detect the illness, as reported by the New Scientist.

The ‘nano nose’ uses a system of six receptors, each one consisting of a solution with gold nano particles not larger than 2 nanometers, each one having a different coating too. Nitrogen atoms form the organic molecules which make up the coating of the nanoparticles.

A “nano-needle” with a tip about one-thousandth the size of a human hair, pokes a living cell causing it to quiver briefly. Once it is withdrawn from the cell, this ORNL nanosensor detects signs of early DNA damage that can lead to cancer.
