Graphene Layers as Functional Biomaterials. From Fabrication and Characterization to Biological Applications

Advanced Materials Interfaces, EarlyView.
Graphene layers are fabricated on Cu foil and transferred onto glass substrates to form double‐ and multi‐layer G‐glass. Raman spectroscopy confirms structural integrity, while SEM and fluorescence microscopy reveal favorable adhesion and spreading of L‐929 fibroblast cells.

Biosynthesis of Spatially Differentiated Cellulose for Flexible All-in-one Supercapacitors. [PDF]

Adv Sci (Weinh)
Spatially differentiated bacterial cellulose is grown by oxygen‐guided biosynthesis to form dense surface regions connected by an open fibrillar interlayer. This architecture supports electroactive material loading, ion transport, and mechanical stability in an all‐in‐one supercapacitor, showing how biological assembly can create device‐ready ...

Culinary Chemistry as a Platform for Interfacial Materials Design

Advanced Materials Interfaces, EarlyView.
Culinary processes control interfaces through heating, shear, gelation, and molecular transport. This Review connects selected gastronomic examples with food‐derived nanomaterials, plasmonic sensing, anthocyanin photovoltaics, and intelligent packaging. Original agar‐based plasmonic films illustrate the proposed translation.
