Bristles hugging a polystyrene sphere

“From the structure of DNA to nautical rope to distant spiral galaxies, helical forms are as abundant as they are useful in nature and manufacturing alike. Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered a way to synthesize and control the formation of nanobristles, akin to tiny hairs, into helical clusters and have further demonstrated the fabrication of such highly ordered clusters, built from similar coiled building blocks, over multiple scales and areas.

The finding has potential use in energy and information storage, photonics, adhesion, capture and release systems, and as an enhancement for the mixing and transport of particles. Lead authors Joanna Aizenberg, Gordon McKay Professor of Materials Science at SEAS and the Susan S. and Kenneth L. Wallach Professor at the Radcliffe Institute for Advanced Study, and L Mahadevan, Lola England de Valpine Professor of Applied Mathematics at SEAS, reported the research in the January 9 issue of Science.”

Self Assembling Cubes

Nanobiotechnology is forecast to be one of the nanosciences that will make near-term and dramatic changes to how we detect and treat disease, and therefore to society.

The Institute for NanoBioTechnology at Johns Hopkins University is one of the rapidly growing number of first-class research organizations that is at the forefront of nanobio.

“The Gracias Lab at Johns Hopkins University develops minimally invasive microscale and nanoscale tools and devices for medicine. They trigger specially prepared 2d surfaces to assemble into 3d objects.”
