    New vaccines and printer ink
    The discovery, which has led to diverse results, is the brainchild of Maren Roman from Virginia Tech in the US.
    is taking nanocrystal research to a new level that may lead to a new
    generation of vaccines and better computer printer ink.The assistant
    professor in the wood science and forest products department of the
    College of Natural Resources at Virginia Tech will be presenting her
    findings at a conference in the US.

    The focus of her research deals with cellulose drug delivery and ink jet printing.
    experimented with taking cellulose nanocrystals and attaching
    antibodies to the surface of the crystals.This design enables the
    nanocrystals to block cell receptors in the body, which may eventually
    be used to create vaccines.Through the same receptor-blocking method,
    this process can combat the effects of some diseases involving
    inflammation of blood vessels, including diabetes, rheumatoid arthritis
    and certain cancers.

    Ink jet printing
    ink jet printing was another research project for Roman.
    experimented with using ink jet printers to deposit the crystals
    because the printers’ main focus is precision.Nanocrystals are tiny and
    pose many difficulties to the people using them – a typical remedy
    involves converting the nanocrystals to a powder.This has risks as
    well, as the powder can be a serious health hazard if inhaled.The ink
    jet printing allows for a safe method of deposition of the
    nanocrystals.Results will be shared at the American Chemical Society
    233rd National Meeting and Exposition in Chicago.
