While working to create strong materials, human engineers haven’t come close to matching what spiders can produce. Spider silk is five times stronger than steel by weight. Besides its strength, spider silk is elastic, and because it is organic, it can be disposed of easily without harming the environment. Years of research have brought scientists closer to their goal of manufacturing spider silk.

The secret to spider silk’s strength lies in special proteins called spidroins and how they are spun into fibers. National Geographic magazine explored ways that spidroins might be used, including medical applications. Since spider silk is organic, it can be used for wound dressings, and spidroin nanocapsules could carry molecules that stimulate the immune system into the body and release them gradually. Gels based on spidroins could coat catheters and surgical meshes to reduce infections and blood clots.

Because of its strength, spider silk could be used to produce bulletproof vests and durable fabrics. The challenge is producing spider silk on a commercial scale because spiders that are kept together tend to be cannibalistic. The solution is to genetically modify silkworms to produce spider silk. China has large mulberry plantations where silkworms feed on mulberry leaves and spin cocoons. Using the CRISPR-Cas9 gene editing tool, silkworm eggs can be altered to produce much stronger spider silk. Research by a Michigan-based company is nearing the point of manufacturing spider silk, or “supersilk.”

Producing spider silk biologically requires a complex molecular structure and a spider’s intricate spinning process. This exemplifies how the natural world reflects wisdom and intelligence, not an accidental creation. Technicians at Kraig Biocraft Laboratories in Lansing, Michigan, have spent 20 years trying to engineer silkworms to spin spider silk. Human engineers aim to develop new products by copying some of what God has created.

The story of the “Tower of Babel” in Genesis 11:1-14 shows that human pride has a long history, yet many still fail to see evidence for God in His creation (Romans 1:20). Throughout the natural world, God’s intelligence is displayed openly, and spider silk is just one example.

Nanofibrils of Spider Silk - Brown Recluse Spider Building Web — Brown Recluse Spider Building Web

Would you like to see a material that is stronger than steel and can stretch ten times more than Kevlar? If so, look at a spider web and marvel at the design of the microscopic nanofibrils of spider silk.

Researchers at William and Mary University, funded by the National Science Foundation, used atomic force microscopy and nuclear magnetic resonance to examine the molecular structure of spider silk as never before. The nanofibrils of spider silk are fibers with diameters in the nanometer range, 10,000 times smaller than a human hair. Spiders generate them using proteins.

The scientists found seven layers of structural hierarchy in the spider silk. At a molecular level, they saw six distinct protein substructures making up the nanofibrils of spider silk, giving it incredible strength and resilience. They hope their research will lead to the development of high-performance synthetic fibers.

The nanofibril structures are so complex that understanding how they give spider silk its properties takes a great deal of time and special equipment. We have discussed spider web materials previously, but this new research shows that it is even more incredible than we realized. Hannes Schniepp, the director of the study, said, “Right now, we’re innovating and discovering in tiny steps, but there’s the larger goal of fully understanding the structure of spider silk. This study solves a piece of the puzzle and takes us closer to the larger dream of one day making materials like nature and, in doing so, create a more sustainable world.”

Studying God’s design in nature has led to an incredible number of things that make our lives more comfortable and enable us to solve some of the problems we face. Romans 1:20 tells us we can know there is a God through the things He has made. One of those things is the nanofibrils of spider silk.
