The computer is a device that helps people work today. But have you ever imagine what computers will be like in the future technology?
Scientists a step closer to a biological computer after the basic building components of digital devices can be made from the bacteria and DNA. Some scientists believe, in the future, tiny biological computers can explore the human body. This technology in the Scientists Eye
Once able to demonstrate we can replicate this section uses bacteria and DNA. “We hope our work can create a new generation of processors that the application of biological information processing can be as important as the electronic equivalent of that,” he continued.
Although still far away, the team demonstrated, the biological logic gates could someday form the building blocks in biological microscopic computers. These devices include sensors that can swim in the arteries to detect the emergence of harmful plaque and quickly gives medication to the affected area.
Other applications include sensors to detect and destroy cancer cells in the body and supervisors of pollution that can be used in environments to detect and neutralize dangerous toxins such as arsenic.
Previous studies only prove the biological logic gates can be made. The advantage of this biological logic gates from previous attempts is, the biological logic gates behave as electronic counterparts.
New biological Gate is also modular. That is, biological gates can be installed together to create different types of logic gates, opening the way to create a more complex biological processor that will build the future.
In one experiment, researchers showed how a biological logic gates capable of imitating the way their electronic counterparts to process information, either with the ‘on’ or ‘off’.
Scientists have made a type of logic gate called ‘AND Gate’ of E. Coli bacteria are commonly found at the bottom of the lower intestine. The team changed with the modification of E. coli DNA.
Bacteria were re-programmed to perform the transfer process from the ‘on’ and ‘off’ the same as when stimulated electronic chemicals. The researchers were also able to show, the biological logic gates can be linked together to form more complex components in the same way when making electronic components.
In another experiment, the researchers created a ‘Not Gate’ and combine it with ‘AND Gate’ to produce ‘NAND Gate’ which is more complex. The next stage of this study is, to see the team trying to develop more complex circuits consisting of several logic gates.
One of the challenges facing the team is, find a way to connect some biological logic gates together, similar to electronic logic gates are interconnected to allow for complex processes.
