Glass nanopore pulls DNA like spaghetti through a needle

Research led by UC Riverside is making it easier to detect and capture DNA from fluid samples such as blood using a tiny glass tube and . The technique, described in the journal Nanoscale, can also improve cancer diagnosis in the future.

DNA, a double-stranded, electrically charged molecule that contains all the information an organism needs to create and organize the building blocks of life, is tightly folded within the . Extracting the DNA from a is time consuming and impractical for many medical and scientific purposes. Fortunately, as die naturally, their membranes burst, releasing the contents, including DNA. This means that a blood , for example, contains many strands of free-floating DNA that should, in theory, be easier to identify and extract in quantity.
