Nano-Probes Stay Inside a Cell's Nucleus for Days

Posted by samzenpus on from the from-the-inside-out dept.

Roland Piquepaille writes "Researchers from the Lawrence Berkeley National Laboratory (LBL) have developed fluorescent and stable nano-probes which can stay inside a cell's nucleus for hours or even days. According to this LBL news release, this will help biologists to better understand nuclear processes that evolve slowly, such as DNA replication, genomic alterations, and cell cycle control. This research was partially based on previous investigations about quantum dots. Now, the researchers want to tailor their quantum dots, which emit different colors depending on their sizes, to check specific chemical reactions inside nuclei, such as how proteins help repair DNA after irradiation. Read more for other details and references and to see how a nano-sized probe is entering a cell's nucleus."

    That's not news. My girlfriend been telling me I've a nano-sized probe for years, now.

    "such as DNA replication"
    Genetic pr0n? Sure tells us a lot about the minds of scientists.
