The bio-based PLA (Polylactic Acid) filament enhanced with G+® Graphene Plus, Grafylon® G+® thanks to its properties of mechanical improvements and biocompatibility, founds applications in medical devices. The addition of graphene nanoplatelets to PLA filaments allows the creation of 3D-printed devices that can be sterilized by near-infrared light exposure at power density analog to sunlight. This method has been used to kill SARS-CoV-2 viral particles on the surface of 3D printed PLA-G by 3 minutes of exposure. The research of the Synthetic Biology and Biotechnology Unit (SynBio) from the University of Padua discovered that Grafylon® G+® (PLA G+®) is biocompatible, does not cause cell death, and does not alter cell proliferation (it has no potential tumor effects).
The field of application is regenerative medicine.
Università degli Studi di Padova and Synbio created the printed scaffolds with PLA and Grafylon® G+® and demonstrated that:
Filo Alfa offers a G+® enhanced PLA filament for 3D printing applications.
Playcast offers innovative 3D printed plasters that are customized according to the patient’s needs.
Graphene Plus enhanced plastic is a material used for this kind of application.
