DNA Computing With Microfluidic Chips

DNA computing uses the individual units of DNA’s two strands (which are selectively bound to each other in a complementary manner) to do complicated mathematical calculations. However, most DNA computing processes are still manual – one needs to add reactants step-by-step to the reaction. Finally, scientists have developed a programmable DNA-based microfluidic device that a personal computer can control, automating DNA calculations.

Scientists believe that DNA-based CPUs will eventually replace electronic CPUs because they use less energy, which will help to reduce global warming. The DNA-based CPUs can perform complex calculations, such as deep learning and mathematical modeling.

The chip has a motor-operated valve system, controlled using a PC or smartphone. The chip and software set up together form a microfluidic processing unit (MPU). The MPU performs a series of reactions to execute a combination of logic operations rapidly and conveniently. Future research will focus on a total DNA computing solution with DNA algorithms and DNA storage systems.
