Smart devices not only make from electronic ones. Commonly it happen, but trust me there is smart device make from hybrid. Bio ingredient take glace by researcher to make some invention. This time, Researchers from Pennsylvania State University tried to make bioplastic from squid teeth.

The problem of plastic waste becomoe the world’s attention. Years by years plastic become monster, not only in land plastic pollute our lovely sea. Therefore, many experts are trying to find ways to replace plastic with other products. Many research from substitute with cassava or another fiber become main idea. Especially with squid teeth.

The extraordinary nature of the newly discovered cui protein inside it is thought to revolutionize materials in a way that conventional plastic cannot do. This was presented by researchers in their report in the journal Frontiers in Chemistry.

The protein is lizard from predatory squid arm ring teeth. Materials from these proteins are environmentally friendly and biodegradable. Another advantage of this material is that it can be produced on a large scale and is sustainable using laboratory culture methods.

“Squid protein can be used to produce next generation materials for other fields including energy, biomedicine, and the security and defense sector,”


Melik Demirel, lead of researcher.

Squid to eat their prey, they depend on a strong suction device at the end of their tentacles. The sucker is equipped with a tooth called squid ring teeth. The researchers found that the tooth had proteins that could be converted into fiber and film to make hard and flexible plastic.

“Nature produces a variety of smart materials that are environmentally sensitive, self-healing, and have extraordinary mechanical functions,”

Melik Demirel said

“We don’t want to spend natural squid resources and therefore we produce this protein in genetically modified bacteria. The process is based on fermentation and uses sugar, water, and oxygen to produce biopolymers,”

Squid contains only about 100 milligrams of SRT protein. Limited to explore so he and his team genetically engineered E. coli bacteria to grow the protein. In other words, this protein can be produced more.

Smart Clothes

According to the researchers, not only can the protein from the squid’s teeth be processed into plastic but also for clothing. SRT protein-coated clothing fibers can produce fabrics that are very hard and can repair themselves if damaged, with little heat and pressure. Not only improving themselves, clothing that is coated with SRT protein is also possible to lead to the development of smart clothing. Such clothing is possible to protect humans from pollutants in the air while watching over our health.
