DNA molecules behave in an interesting way. Gang had previously worked with the paper’s lead author, Brookhaven postdoctoral researcher Aaron Michelson, on an experiment using DNA structures to build a robust framework for novel materials. Oleg Gang, pictured behind, and Aaron Michelson use the specialized resources at CFN to measure the surprising strength of this novel material structure. This novel technology has inspired an array of innovative applications-from drug delivery to electronics. Oleg Gang, a materials scientist at the Center for Functional Nanomaterials (CFN), a DOE Office of Science User Facility at Brookhaven Lab, and a professor at Columbia University, has been leveraging DNA’s unique properties for materials synthesis for years, resulting in numerous discoveries. Their resilience and simplicity have intrigued material scientists and inspired many interesting experiments. The material DNA is made of is known as a polymer, a class of tough, elastic materials that includes plastic and rubber. In living things, deoxyribonucleic acid, more commonly known as DNA, carries biological information that instructs the cells of organisms on how to form, grow, and reproduce. DNA-The Building Blocks for Life and More The results were published in the journal Ce ll R eports Physical Science. Materials that possess both of these qualities are uncommon, and further research could lead to novel engineering and defense applications. Department of Energy’s (DOE) Brookhaven National Laboratory were able to fabricate a pure form of glass and coat specialized pieces of DNA with it to create a material that was not only stronger than steel, but incredibly lightweight. Scientists at the Columbia University, the University of Connecticut, and the U.S. This is particularly evident in most types of glass, leading to its reputation as a fragile material. Such vulnerabilities can cause them to fracture under pressure. In broader-scale production, and even in natural settings, numerous materials are susceptible to defects and contaminants that can compromise their intricate architecture. Working at the nanoscale provides scientists with a deep understanding and precision in crafting and analyzing materials. (Artist’s concept) Researchers developed a light yet strong material by combining two unexpected ingredients-DNA and glass. This groundbreaking discovery, utilizing the nanoscale structuring of glass and the unique properties of DNA, holds potential for diverse applications in engineering and defense. Researchers have created a novel material by coating DNA with a pure form of glass, resulting in a substance that is lighter and stronger than steel.
