DNA nanotechnology is a new budding field altogether. In this field of science, artificial nucleic acid is manufactured for being used in varied technologies

Nanotechnology has become the latest trend. Nanoscale materials are being used in every field. The researchers are working on developing various assets that can be used for treating cancer, infections and for gene modification. So far, gold nanoparticles have been doped with the DNA for the patients for detection of bacteria in blood to determine the kind and type of infection.

DNA nanotechnology is another branch of nanotechnology that studies the design and application of synthetic structures on the basis of DNA. DNA nanotechnology is not concerned with the genetic information in the DNA but works on the chemical and physical properties of DNA.


DNA nanotechnology is a new budding field altogether. In this field of science, artificial nucleic acid is manufactured for being used in varied technologies. The artificially created nucleic acids are not used for carrying the information forward. Instead, they are used in nanotechnology as the non-biological engineering materials.

DNA nanotechnology is being widely used for curing problematic areas in structural biology, biophysics along with the determination of structures. Nanomedicine is also being researched about for implementation.

Nadrian Seeman in 1980s was the first person to lay down the basic core of DNA nanotechnology. The nucleic acids from the double helix structure owing to their pairing rules. DNA nanotechnology is a great way for the formation of a complex structure that provides control over the nanoscale features.

The DNA origami rods are being used as a replacement for liquid crystals in protein NMR spectroscopy since DNA origami is more tolerant towards the detergents used for suspension of membrane proteins in the solution. The study of protein folding and enzyme function has become easier by using DNA nanotechnology.

There are various instances where nanotechnology coupled with DNA has worked wonders. For example, gold nanoparticles help in identification of cancer and other diseases. It also helps delivery of genes, chemical messengers or drugs inside the cells. The DNA molecules can be packed into the nanoparticles and then can be inserted into the cells.


Journals like Nature nanotechnology is full of papers that consist of DNA and its ability of self-assembling itself in varied forms of nanomachines and nanostructures. Nanoscientists love working with DNA since DNA itself is a nanoscale material with a lot of study techniques available. The self-assembly process of DNA helps in carrying the information forward.

The use of DNA in nanotechnology for organising other nanomaterials is a successful venture. Owing to the positive feedback, RNA nanotechnology is beginning to emerge as a new field.
