A new method for measuring extremely tiny objects could lead to cheaper, more accurate sensors for use in fields including medical research and gas detection. The study found that nanoscale devices using electromagnetism would be sensitive enough to determine the mass of viruses a hundred billion times lighter than a strand of human hair.
