 **\n\nAbstract\nChirality transfer across length scales is an intriguing a
 nd universal phenomenon. Both in nature and in materials science\, complex
  architectures composed of bio-based chiral building blocks are responsibl
 e for unique optical responses from bright and vivid colourations to extre
 mely large dichroism. When it comes to working with naturally derived chir
 al building blocks\, however\, the challenge lies in understanding how the
  properties of individual building blocks relate to the emergent features 
 of large-scale architectures and structures. Our research addresses this g
 ap by investigating the origins of mesophase chirality in bio-derived part
 icles such as cellulose and chitin nanocrystal suspensions. Through a comb
 ination of quantitative morphological analysis of individual nanoparticles
 \, final architecture\, and their assemblies\, we showcase the functionali
 ty of such chiral materials in the context of optical materials\, includin
 g plasmonic ones\, also providing examples of how such materials can be pr
 oduced at scale.\n\nBio\nSilvia Vignolini is the Director of the Sustainab
 le and Bio-inspired Materials Department at the Max Plank for Colloid and 
 Interfaces in Potsdam and a University Professor in Sustainability and Bio
 -inspired materials at the Chemistry Department in Cambridge. She studied 
 Physics at the University of Florence\, Italy. In 2009\, she was awarded a
  PhD in Solid State Physics at the European Laboratory for non-Linear Spec
 troscopy and the Physics Department at the University of Florence. In 2010
 \, she moved to Cambridge as a post-doctoral research associate working in
  the Cavendish Laboratory and the Plant Science Department. Her research i
 nterest lies at the interface of chemistry\, soft-matter physics\, optics\
 , and biology. In particular\, her research focuses on the study of how bi
 opolymers are assembled into complex architectures within living organisms
  and how they can be exploited to fabricate a sustainable functional mater
 ials.
