Graphene, a very recent rising star, with an atomically thin, 2D honeycomb lattice that consists of sp2-hybridized carbons, exhibits remarkable electronic, thermal, optical, and mechanical properties. Many attempts have been made to demonstrate the applications of graphene and graphene-based materials in several fields, nevertheless the combination of bio-inspired materials with graphene and their related properties have attracted attention only recently. In particular, the electrical and optical properties of graphene with bio-inspired materials could lead to novel graphene-based devices with remarkable performance. This feature article will briefly introduce the recent progress in this direction. The first part of the article will report on some bio-inspired modifications useful to modulate the electrical performance of graphene composites as well as interesting examples with silk, nanocellulose and proteins. In the second part, the recent progress in bio-inspired modification and applications of graphene in photodetection, organic solar cells and photothermal therapy is discussed. From this perspective this field of research is still at an early stage but it might become a hot topic in the near future.

Abstract
Graphene, a very recent rising star, with an atomically thin, 2D honeycomb lattice that consists of sp2-hybridized carbons, exhibits remarkable electronic, thermal, optical, and mechanical properties. Many attempts have been made to demonstrate the applications of graphene and graphene-based materials in several fields, nevertheless the combination of bio-inspired materials with graphene and their related properties have attracted attention only recently. In particular, the electrical and optical properties of graphene with bio-inspired materials could lead to novel graphene-based devices with remarkable performance. This feature article will briefly introduce the recent progress in this direction. The first part of the article will report on some bio-inspired modifications useful to modulate the electrical performance of graphene composites as well as interesting examples with silk, nanocellulose and proteins. In the second part, the recent progress in bio-inspired modification and applications of graphene in photodetection, organic solar cells and photothermal therapy is discussed. From this perspective this field of research is still at an early stage but it might become a hot topic in the near future.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
