TEL AVIV, Israel,\u00a0September 29, 2010\u00a0\/PRNewswire\/ — A revolutionary new spherical nanostructure, fully derived from very simple organic elements, yet strong as steel, has been developed and characterized at the laboratories of\u00a0Ehud Gazit\u00a0of\u00a0Tel Aviv University\u00a0and\u00a0Itay Rousso\u00a0of the Weizmann Institute of Science. Lightweight and exceptionally strong, easy and inexpensive to produce, friendly to the environment and biologically compatible, these promising bio-inspired nano-spheres have innumerable potential uses – from durable composite materials to medical implants. The groundbreaking work was recently published in the leading journal Angewandte Chemie.<\/p>\n

<\/p>\n

The researchers, Prof. Gazit, Dr.\u00a0Lihi Adler-Abramovich\u00a0and\u00a0Inbal Yanai\u00a0from TAU’s Department of Molecular Biology and Biotechnology, working in collaboration with Dr.\u00a0Itay Rousso\u00a0and\u00a0Nitzan Kol\u00a0from the Weizmann Institute and\u00a0David Barlam\u00a0and Roni Shneck of\u00a0Ben-Gurion University, used a simple dipeptide, consisting of only two amino acids, to form spherical nanostructures. Self-assembling under ambient conditions – without any heating or manipulation – this remarkable new material is the first bio-inspired nano-material known to date that is mechanically equal and even superior to many metallic substances. While demonstrating chemical properties similar to those of the ultra-rigid Kevlar(R) polymer, already used for bullet-proof vests, the new substance is built from much simpler building blocks, enabling some important advantages: manipulation and deposition at the nano-scale, the fabrication of nano-materials of tubular, spherical and other geometries, and spontaneous formation by self-assembly. Here, indeed is a perfect building block for numerous applications:<\/p>\n

Hard and strong as steel, this new nanostructure is an ideal element for the reinforcement of composite materials used in the space, aviation and transportation industries; biologically compatible yet extremely rigid and durable, it is an excellent candidate for replacing metallic implants; tough, light and impenetrable, it is an exceptional option for manufacturing bullet-proof vests; – to name just a few high-potential uses.<\/p>\n

The new nanotechnology development now emerging from\u00a0Tel Aviv University\u00a0is based on extensive research which began in Prof. Gazit’s laboratory in 2003. In an earlier achievement, the team was able to fabricate tubular nanostructures that assemble themselves into vast \u00abforests\u00bb featuring exceptional mechanical and physical properties. This earlier work, based on the doctoral thesis of Dr.\u00a0Lihi Adler-Abramovich, and published in 2009 in the prestigious Nature Nanotechnology scientific journal, may eventually generate self-cleaning windows and solar panels, as well as supreme energy storage devices with exceptionally high energy density.<\/p>\n
