Future of DNA Chips

Ubiquity and need of computing technology is going to change our life. As we are going in time, need of faster and faster is increasing. Quantum computer and DNA chip based computer should be primarily developed that could feed our need. Scientist at IBM are experimenting with using DNA molecules as a way to create tiny circuits that could form basis of smaller, more powerful computer chips. Its great step of IBM in this field. The company is researching ways in which DNA can arrange itself into patterns on the surface of chip, and them act as a kind of scaffolding on to which millions of tiny carbon nanotube and nanoparticles could act as the wires and transistors on future computer chips. This technique was first given by Paul Rothmund, a scientist at California Institute of Technology, who figured out that DNA molecules can be made to “self assemble” into any form such triangles, squares, and stars. The approach takes advantages of DNA’s natural ability to incorporate large amounts of complex information that can be applied to different types of activities. To make a chip the scientist first creat lithographic templates, the patterns from which circuit are made, using traditional chip making technology. After, they pour DNA solution over the surface of the silicon and the tiny triangles and squares(what scientist call DNA origami) line themselves up to the pattern etched out using lithography. The ability for the DNA structures to self assemble is a key element needed for achieving greater precision in the design and manufacture chip. However, if it works as planned, it could lead to a new way of fabricating features on the surface of chip that allows semiconductors to be made even smaller, faster and power efficient than they are today. A whole new world of DNA computers …!
