DNA NANOTECHNOLOGY

Scientists have created a clever system to spot very small doses of kanamycin, an antibiotic, in milk. Instead of relying just on enzymes stuck to DNA, they attached the walker to tiny magnetic beads. This trick helps separate the useful parts from the junk faster and more cleanly. Once kanamycin s

A new study shows that tiny DNA shapes, called tetrahedral framework nucleic acids or tFNAs, can calm the overactive immune system that attacks the thyroid in Hashimoto’s disease. Researchers first treated mice with these nanostructures and saw a clear shrinkage of the swollen gland, fewer immune ce
