Invisible to the naked eye, the objects are 12 nm (12 billionths of a meter) wide. That's big for a nanoscale molecule. It's huge, said Hla, an associate professor of physics and astronomy. This man-made fractal molecule resembles a Star of David.This man-made structure is one of the first nanoscale, non-branched fractal molecules ever produced, said Newkome, who is lead author on the study's paper (published online today by the journal Science).ractals are irregular curves or shapes that retain the same pattern when reduced or magnified. The molecule in the study, for example, is composed of six rings, which are made up of six smaller rings, and so on, Hla said. Snowflakes, broccoli florets or tree bark would be just a few examples from nature.
An organic molecule is a molecule that is createdâor theoretically could be createdâby a living organism. Sugar, DNA and fat are all organic molecules. Quartz, graphite and plastic are not organic molecules. Most organic molecules have a carbon backbone, meaning that their structure is made up of carbon atoms bonded to other carbon atoms. There are still other atoms in the molecule, but without the structural support provided by carbon, the entire molecule would all fall apart.
