These techniques could lead to new technologies such as a filter for bioremediation, which uses biological molecules to remove herbicides from tainted water, or synthetic matrices to help study human disease or aid tissue engineering to restore, improve or preserve damaged tissues or organs. Assemblies of natural proteins are also dynamic, forming and dissolving in response to stimuli.The next steps are to further develop the technology and expand the range of proteins that form fractal shapes as well as use different stimuli, such as chemicals and light.

The technique that turns proteins into never-ending patterns that look like flowers, trees or snowflakes, could be utilised to engineer a filter for tainted water and human tissues."Biomolecular engineers have been working on modifying the building blocks of life - proteins, DNA and lipids - to mimic nature and form interesting and useful shapes and structures," said Sagar D. Examples include trees, leaves, and pineapples. Khare, the senior author of the study.In nature, building blocks such as protein molecules are assembled into larger structures custom special bolts manufacturers for specific purposes."Our team developed a framework for engineering existing proteins into fractal shapes," Khare added. Tiny protein molecules assemble to form structures that are scaled up and can be as long as tendons.The team used protein engineering software to design proteins that bind to each other, so they form a fractal, tree-like shape in response to biological stimuli, such as in a cell, tissue or organism.

A classic example is collagen, which forms connective tissue in our bodies and is strong and flexible because of how it is organised. They can also manipulate the dimensions of the shapes, so they resemble flowers, trees or snowflakes, which are visualised using special microscopy techniques.The study was published in the journal Nature Chemistry.The research team developed a technique for assembling proteins into a fractal, or geometric shapes that are repeated over and over.
