Director of Center for Research on Advanced Fiber Technologies (CRAFT), Dorothy Foehr Huck Endowed Chair in Biommetric Materials, Lloyd and MelikDemirel at Penn State University, USA claimed that “Squid proteins can be used to produce next generation materials for an array of fields including energy and biomedicine, as well as the security and defense sector. “We reviewed the current knowledge on squid ring teeth-based materials, which are an excellent alternative to plastics because they are eco-friendly and environmentally sustainable.

On awakening the humanity to the consequences of the production of plastic, beginning to pay attention to the warning for nature and their solution.

Demirel explained that “Nature produces a variety of smart materials capable of environmental sensing, self-healing and exceptional mechanical function. These materials, or biopolymers, have unique physical properties that are not readily found in synthetic polymers like plastic. Importantly, biopolymers are sustainable and can be engineered to enhance their physical properties”.

The oceans have borne the impact of plastic pollution, at the center of the hunt for sustainable substitute. The recently-discovered protein from squid ring teeth (SRT) locating circular predatory appendages on the suction cups of squid, utilized to powerfully clutch quarry gaining interest owing to the sustainable production and remarkable properties.

Strength, flexibility and elasticity of SRT-based materials for self-healing, electrical, thermal conducting and optical properties can be explained by various molecular arrangements can be accepted. SRT proteins are made of building blocks set in such way that separation of micro-phase takes place. This is equivalent to water and oil but on slighter nano-scale. The blocks cannot be separated completely for producing two different layers instead of the molecular-level shapes are produced like ordered layers or disordered tangles and cylindrical blocks. The shapes produced describe the material property and scientists have acknowledged to generate SRT-based products for several applications.

In the textile sector, SRT protein can address the important sources of microplastic pollution by delivering an abrasion-resistant coating decreasing the erosion of microfiber in washing machines. In the same way, self-healing coating of SRT protein can augment the prolonged existence and safeguarding of damage-prone biochemical implants, in addition of garments customized for protection against biological and chemical warfare agents.

It is possible to interrupt several layers of SRT proteins of other technology or compounds, leading to the development of ‘smart’ clothes protecting from the pollutants in air for keeping an eye on health. The optical properties of SRT-based materials mean that these clothes displaying information about our surroundings or health. Flexible SRT-based photonic devices of the components creating, detecting lighting or manipulating like optical displays and LEDs that are affected with hard materials such as quartz and glass are in development.

Demirel claims that “SRT photonics are biocompatible and biodegradable so could be used to make not only wearable health monitors but also implantable devices for biosensing and biodetection”.
