演 題：Self-assembly of Carbohydrate Block Copolymers: From Glyconanoparticles to Thin Films
to Photonic Crystals
講演概要：To date, numerous studies have been focused on the self-assembly of petroleum-based BCPs
for potential applications in multidisciplinary fields, such as nanoparticles for drug delivery, or nano-organized films
for biosensors, or nanolithography, etc. Such materials are derived from fossil resources that are being rapidly depleted
and have negative environmental impacts. In contrast, carbohydrates are abundant, renewable and constitute
a sustainable source of materials. This is currently attracting much interest in various sectors and their industrial
applications at the nanoscale level will have to expand quickly in response to the transition to a bio-based economy.
The self-assembly of carbohydrate BCP systems1-4 at the nanoscale level via the bottom-up approach, has allowed
the conception of nanostructured thin films and nanoparticles (micelles, vesicles,…) whose external shell is made from
carbohydrates. We will present recent results on the self-assemblies of carbohydrate-based block copolymer leading
to nanoparticles presenting different shapes (spherical, cubic, …), highly nanostructured thin films for
nanobioelectronic applications and more recently brush-like glycopolymers exhibiting photonic crystals behavior
leading to colored materials.
