New DNA-Based Microfluidic Chip Can Be Programmed To Solve Complex Math Problems
The term “DNA” is immediately reminiscent of a double-stranded helix that contains all of our genetic information. However, the individual units of the two strands are pairs of molecules that are attached to each other in a selective and complementary manner. After all, this pairing property can be used to perform complex mathematical calculations, which form the basis of DNA computing.
Since DNA has only two strands, even simple calculations require multiple chemical reactions using different sets of DNA. In most existing studies, the DNA of each reaction is manually added to one reaction tube, one at a time, making the process very cumbersome. Microfluidic chips, consisting of narrow channels etched into materials such as plastic, provide a way to automate the process. However, despite their promises, the use of microfluidic chips for DNA computing remains unexplored.
In a recent article — Now available online ACS Nano It was published on July 7, 2021 and on July 27, 2021 in Volume 15, Issue 7 of the Journal. A team of scientists from Incheon National University (INU) in South Korea has unveiled a programmable DNA-based microfluidic chip. A personal computer for performing DNA calculations. “Our hope is that DNA-based CPUs will replace electronic CPUs in the future because they consume less power and help global warming. DNA-based CPUs are deep learning solutions and mathematical modeling. We also provide a platform for complex calculations such as, “said Dr. Youngjun Song of INU, who led the study.
What makes the designed chip special is the electric valve system that can be operated using a PC or smartphone. The chip and software setups work together to form a microfluidic processing unit (MPU). Thanks to the valve system, the MPU was able to perform a series of reactions to perform a combination of logical operations in a quick and convenient way.

SpiceJet expands its domestic network with 8 new flights that will connect Jaipur with Varanasi, Amritsar and Ahmedabad and also link Ahmedabad with Pune.
SpiceJet is further expanding its domestic network with the launch of eight new flights starting November 15.
In the statement released on Wednesday, the airline announced that these new routes will connect Jaipur with Varanasi, Amritsar and Ahmedabad, while also linking Ahmedabad with Pune. This expansion follows the recent launch of 32 new flights in October 2024, including two international flights connecting Delhi with Phuket.
Last month, SpiceJet also commenced UDAN flights linking Shivamogga in Karnataka with Chennai and Hyderabad, and introduced double daily flights between Chennai and Kochi, enhancing connectivity across key regional and metropolitan cities.
“We are excited to announce the launch of new flights from Jaipur to Varanasi, Amritsar, and Ahmedabad, as well as from Ahmedabad to Pune, providing our passengers with greater flexibility and convenience,” SpiceJet Chief Business Officer Debojo Maharshi said.
“These new flights reflect our commitment to supporting passenger demand across tier-II cities and beyond. With our expanded winter schedule, including international and UDAN routes, we aim to provide our customers with greater convenience, affordability, and seamless travel experiences,” Maharshi added.
SpiceJet will deploy its 78-seater Q400 aircraft in these sectors. Bookings for the new flights are now open and tickets are available at the website of the airline, SpiceJet’s mobile app and through online travel portals and travel agents.
On Monday, the airline received a significant boost, with Acuite Ratings & Research Limited upgrading its long-term rating by four notches to ‘B ‘ and its short-term rating to A4. The rating agency has also assigned a ‘Stable’ outlook to the airline.
