A new breakthrough in biotechnology can make bacteria fabrics

With the advancement of science and technology, many traditional items have more extension functions in addition to the original functional attributes, such as clocks, not only timing, but also intelligent monitoring functions; as well as smart sports shoes. Similarly, clothing is no exception. According to foreign media reports, BioLogic is a team at the Massachusetts Institute of Technology (MIT) Media Lab who recently launched a new project to try to use microbes to add scientific capabilities to clothing.

BioLogic uses Bacillus subtilis, which, like pine cones, automatically expands and contracts according to the humidity of the air. The greater the humidity, the larger the fabric expands. So, using this principle, BioLogic worked with designers to invent a new style of clothing called "Second Skin," which became more breathable as the wearer's temperature and humidity increased.

Bacillus subtilis natto is a common ingredient in Japanese cuisine, and the BioLogic team made it into a biofilm that was integrated into spandex fabric. The shape of the biofilm is different, and the effect will change. Moreover, the breathability of the biofilm is directly proportional to the humidity response. When the humidity reaches 100%, the biofilm will be completely open and the air permeability will be maximized.

Yao Lining, head of the BioLogic team, said that in terms of designers, biological technology is promising because they are life-giving and have great adaptability. The use of natural laws to adapt to the environment can achieve many functions such as electronic products that cannot be realized, such as these natto Bacillus subtilis. The substances made up of these cells have the natural ability to expand and contract, and they have a more intelligent "smart". Well, it would be better if it could solve the aesthetic problem.

Yao Lining pointed out that in the future, designers may also develop richer biological functions by modifying the DNA structure of cells, such as adding luminescent substances such as jellyfish and fireflies, and developing other luminescent natural luminescent materials (if you have seen "Sherlock" You may have already seen this technique); or add bacteria that devour contaminants, make fabrics that clean the air, and so on. If you can put biotechnology into practice and don't make a nonsense idea, then maybe you really open up a new market.
