Today’s methods of introducing medicine into humans’ system remain rudimentary. The solution often has to travel throughout the entire body before it finds the place where it is needed. However, scientists turned to microscopic robots as a vision of alternative method. The results of their endeavors are DNA robots with limbs that can take a direct route to the issue and discharge the medicine once on site.
Californian Researchers Programmed DNA Robots to Sort and Deliver Molecules
The world of medicine has a new futuristic perspective that appeared with an insightful article in publication Science. A team of researchers at the California Institute of Technology made groundbreaking progress within nanotech area. Anupama Thubagere and Lulu Qian managed to build tiny robots made of a sole string of DNA.
Afterward, the duo managed to program these particles to sort and deliver individual molecules to a predetermined location. The end goal is to use these microscopic robots to operate life-saving or research-focused molecules throughout the human body. It can revolutionize drug delivery, infection treatments, and microscopic measurements.
While there were prior experiments done in this branch of nanotech, the Californian team was the first one to imbue this segment with complex tasks. The novelties come from programming such tiny robots to carry out cargo-sorting tasks and even work in a group based on collaboration for the sake of one goal.
The Experiment Concluded that the Work Needs Improvement yet It Is Groundbreaking
The deoxyribonucleic acid is made of four nucleotides, namely adenine, thymine, cytosine, and guanine. Researchers found a way through advanced nanotech to manipulate this biologic material into nanostructures and program them to perform certain tasks. This is how DNA robots came to life. They also received two feet, hand, arm, and a leg for better dexterity and movement skills.
“The DNA robot is just a single-stranded molecule, it’s like a floppy rope when it’s not attached to anything.”
The experiment ended with 80% accuracy in molecule sorting and intercepted issues with certain parts of the robots. Therefore, there is room for improvement. Nonetheless, the new study is proof that the future of this new industry is viable and encourages scientists to delve into more groundbreaking studies.
