We've Got the Whole World in Our Hands

Scanning electron microscope image of resin fiber and polystyrene assembly from Science, 19 Feb 2010, Vol 327, Issue 5968

    This fascinating image captured through electron microscopy depicts fibers of epoxy resin 250 nm in diameter assembling around a green polystyrene sphere, about 2 µm in diameter.  The photograph reveals how individual fibers, which are powerless alone, can work to grip and support the orb, embodying cooperation at the microscale.  The image was produced with a scanning electron microscope and digitally enhanced for color.

    The self-assembling polymers shown in the image were designed by materials scientist Joanna Aizenberg and her team at Harvard University, aiming to create energy-efficient materials.  The fibers are not chemically or magnetically attracted to the sphere but rather are adhered to it through capillary action.  The researchers took photos of this micrometer-scale cooperation, demonstrating a new way of controlling the self-assembly of polymers.

    According to Aizenberg, the photograph can also symbolize people's cooperative efforts to save Earth.  Each fiber represents a person or organization collaborating to support the planet. Potential applications of self-assembling polymers include drug release and self-cleaning materials. Theoretically, the polymers could grab dust particles or bacteria and release them to flush the contaminants away. This image and Aizenberg’s message resonated with me because of their similarities with a familiar Earth Day graphic that alludes to the power of collaboration in the stewardship of our planet.
