Research roadmap for nanosafety - Part III: Closer to the market (CTTM)
No full textNano-products and nano-enabled applications need a clear and easy-to-follow human and environmental safety framework for the development along the innovation chain from initial idea to market and beyond that facilitates navigation through the complex regulatory and approval processes under which different product categories fall. The missing framework results in a lack of (i) solid data regarding roadblocks to market penetration of nano-enabled products as well as the absence of (ii) transparency in terms of which products (e.g. containing nanomaterials (NMs); nano-enabled products) are on the market (e.g. registries) and voluntary schemes and labelling requirements for cosmetics and food, which processes are used for manufacturing nano-enabled products, and (iii) meager inclusiveness in the dialogue (between all stakeholders) most likely exist as a result of the missing framework. The Closer-to-the-Market-Roadmap (abbrev. CTTM) aims at speeding up the progress towards market implementation of nanotechnologies by outlining the steps needed to develop such a framework. In its current form it is addressed towards policy makers, but the ultimate framework will be designed for use by SME and enterprise organisations

Controlled Supramolecular Self-Assembly of-Large Nanoparticles in Amphiphilic Brush Block Copolymers
No full textTo date the self-assembly of ordered metal nanoparticle (NP)/block copolymer hybrid materials has been limited to NPs with core diameters (D-core) of less than 10 nm, which represents only a very small fraction of NPs with attractive size-dependent physical properties. Here this limitation has been circumvented using amphiphilic brush block copolymers as templates for the self-assembly of ordered, periodic hybrid materials containing large NPs beyond 10 nm. Gold NPs (D-core = 15.8 +/- 1.3 nm) bearing poly(4-vinylphenol) ligands were selectively incorporated within the hydrophilic domains of a phase-separated (polynorbornene-g-polystyrene)-b-(polynorbornene-g-poly(ethylene oxide)) copolymer via hydrogen bonding between the phenol groups on gold and the PEO side chains of the brush block copolymer. Well-ordered NP arrays with an inverse cylindrical morphology were readily generated through an NP-driven order order transition of the brush block copolymer
