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.
Polymers are very large molecules made of repeating patterns of small molecules, called monomers. Many polymers are made by repeating the same small molecule over and over again. Others are made from two monomers linked in a pattern.While most polymers with which you are familiar are man-made, there are some biological polymers â proteins, nucleic acids, and complex carbohydrates â that are fundamental to the way your body functions.thers are made from two monomers linked in a pattern.
