    The field of nanotechnology is shifting towards active nanostructures, which change during operation. Research shows a significant increase in publications on these advanced nanodevices since 2006.

    Area of Science:

    • Nanotechnology
    • Materials Science
    • Engineering

    Background:

    • Nanotechnology development is transitioning from passive to active nanostructures.
    • Active nanostructures, defined by the National Science Foundation, evolve during operation.
    • This shift necessitates new risk assessment approaches due to potential societal impacts.

    Purpose of the Study:

    • To determine if a shift towards active nanostructures is occurring.
    • To characterize emerging areas of active nanostructure research.
    • To distinguish between passive and active nanotechnology publications.

    Main Methods:

    • Developed a research publication search strategy based on the NSF definition of active nanostructures.
    • Conducted bibliometric analyses of publications from 1995 to 2008.
