26-27 September 2021: Poster presentation at Biofabrication2021
Irene Chiesa had a virtual poster presentation entitled “4D printed carbon nanotubes embedded silk-based bioarchitectures for intestinal surgery applications” at the International Conference on Biofabrication 2021
Highlight of the presentation:
- Bilayer tubes made of PHBV and RS/CNTs, to be used as suturless clips for intestinal anastomosis, were successfully fabricated by 4D printing.
- Smart patches were fabricated to in vivo monitor physiological forces
September 2021: New paper out!
New paper entitled “Biomimetic Tendrils by Four Dimensional Printing Bimorph Springs with Torsion and Contraction Properties Based on Bio-Compatible Graphene/Silk Fibroin and Poly(3-Hydroxybutyrate-co-3-Hydroxyvalerate)” is published on Advanced Functional Materials (IF: 18.808)
Highlights of the study:
- Smart core-shell tendril-like structure were fabricated via 4D printing, to be used for distraction enterogenesis.
- Thanks to the propel spatial arrangment of PHBV and regenerated silk, the 4D printed structure has the capability to self-twist and contract with the increase of temperature and humidity.
- The mechanical properties of the bimorph structure were tuned and improved with the addition graphene nanoplatelets.
