The United States Patent and Trademark Office (USPTO) has issued a patent on our application for Shrilk.
The patent “High Strength Chitin Composite Material and Method of Making”, initially presented in 2011, covers Shrilk itself as well as all the processes to produce it and its variants.
It is described as:
“An organic composite material formed from carbohydrates and proteins. More specifically, the invention relates to a composite biocompatible material formed from layers of Chitosan and proteins, such as Fibroin, having superior strength and energy-dissipating properties”
It includes all the possible forms we have achieved (film, fiber, sponge, mesh, foam, nanoscale structure…) and the enzymatic method to attach it to organic and inorganic surfaces. This last achievement is a key factor for its inclusion in medical and microfluidic devices.
