Engineers invent: A new silk-based programmable material

Engineers from Tufts University created a new pattern of solids which are made from silk protein and that can be programmed with functions like biological, chemical or optical functions, which will give a response to light, deliver drugs even these can change color with strain.

Now the question is how it really works. ?????  It is a water-based fabrication method which follows the protein self-assembly. During research, engineers generate 3-D bulk materials from silk fibroin and the protein gives that silk its durability.After that, they manipulate that material to make more solid forms, and at any level that can be enclosed with pre-designed functions.

The question may arise that why they choose silk?

They use it because silk has a property of unique crystalline structures and that property makes the silk as one of the toughest material in nature. Now, what is fibroin? It is actually a protein which is insoluble and can be found in silk. It has a property which can save other materials from degradation when these materials are degradable.
