Tinkering with silk-based materials

A (sustainable) designer-in-lab

My first designer-in-lab experience occurred at SilkLab (Tufts University, Boston, MA); here, as a visiting PhD for six months, I had the opportunity to learn new lab skills and deepen my knowledge of silk-based materials, especially working with fibroin (the silk protein). Willing to understand how designers can contribute in highly scientific environments and transdisciplinary projects, I have dealt with new materials development, the environmental assessment of lab processes, and a visual representation of material tunability to facilitate scientists and designers in applying newly discovered materials. The initial visiting period was characterised mainly by creating a series of materials drafts and by a tireless learning process, asking and imitating colleagues in the creation of basic fibroin-based materials. The tinkering of a designer who enters a scientific laboratory for the first time is an ongoing work of assimilation of new notions that modify and expand the range of possible material experiments imaginable. The DIY-Material approach, empowered and informed by the possibilities of scientific lab space, finally paid off, and I could actively contribute to developing new fibroin applications and materials by collaborating with chemists and material scientists.

Publications with the first results are expected for 2024

Fibroin-based materials

Silk threads from the Bombyx Mori cocoon are made up of two fundamental components, fibroin and sericin. These proteins have a similar composition but differ substantially in their chemical behaviour, physical and structural characteristics: fibroin constitutes the most structural part, while sericin serves as a rubbery and sticky coating. Fibroin is appreciated for its mechanical properties, tunability, controllable biodegradability, and the possibility to design new materials from the nano to the macroscale. This protein has been widely experimented in the biomedical sector, also thanks to other remarkable features: its biocompatibility and its ability to maintain the functions of biological components.

Team

The SilkLab, headed by Professor Fiorenzo Omenetto, is an interdisciplinary research lab that investigates materials at the intersection of technology and life sciences, especially leading to the use of fibroin as a building block material for various applications. In the lab I was supervised by Prof. Fiorenzo Omenetto and by Dr. Giulia Guidetti; In the Lab I collaborated with different colleagues on different projects; in particular, the work done with the chemist Marco Lopresti has been fundamental for the development of new material outcomes.
