Spiber was established in 2007 to achieve industrial commercialization of synthetic spider silk and other high-performance protein materials. They succeeded to establish the basic technology necessary for mass production of synthetic spider silk for the first time in the world. Their new bio-materials derived from spider silk are named QMONOS?. This new material, QMONOS?, has a ?limitless possibilities to revolute world manufacturing.

Properties of Spider Silk

The greatest property of spider silk is its incredible toughness. This material has the equivalent strength of carbon fiber, but an amazing 40 times the toughness. *Toughness : A value indicating the amount of energy absorbed before rupture.

Spiber’s Research and Development Processes

The artificial spider silk produced at Spiber is optimized through the following four processes.

First, the silk-producing regions of the spider’s genome are analyzed. We then artificially synthesize a gene to maximize strength, elasticity, and the potential for industrial productivity using genetic engineering techniques. Second, we introduce this recombinant gene into a microbe and culture it, we then separate the spider silk protein from the host microbes. Third, the resulting protein is refined and spun into a fiber. Finally, this fiber is then used in the development of a variety of products and the resulting properties are examined. The results of these examinations, including productivity and fiber properties, are stored in a database, and this hypothesis-driven trial and error knowledge is used in the next series of development. In this way, each iteration of the material becomes more and more refined as each generation of research progresses.

Features of Spiber’s Materials

Spider silk is not the only protein offering amazing possibilities.

At Spiber, our research focuses on the structural proteins of biomaterials produced by living organisms to build tissues such as skin, nails, and hair, and then fashioning these materials into a dream platform of physical resources for research and development.


Remarkable qualities of Spiber’s platform

・Ultra High Performance
There are many naturally-occurring structural proteins with remarkable performance. Spider silk is tougher than steel, and the resilin found in squid beaks is both more elastic than synthetic rubber and possesses more than three times the stiffnFour ess of synthetic PC or PPE resins.
・Tailor-Made Molecular Design
Conventional artificial polymers are composed of one or two types of molecules, whereas proteins are combinations of 20 different kinds of amino acids. The combination of these 20 amino acids have countless potential new structures and properties hidden within them. By controlling these combinations at the molecular level it is possible to create materials that are tailor-made for a specific purpose or need.
・Biomass-Derived
Today’s conventional polymers are dependent on limited petroleum resources. Structural proteins produced through the fermentation of biomass are an almost inexhaustible renewable resource.
・Single Process - Multi Output
The fermentation process using microorganisms enables the production of a wide variety of proteins from the same process and using the same biomass feedstock by simply changing the genes that provide the code for each target protein. This means, once a large-scale production facility is established, large quantities of new materials can be introduced to the market each year. People will be free to imagine a new material and create a molecule from which to make it.
