Mitigating Human IAPP Amyloidogenesis In Vivo with Chiral Silica Nanoribbons
Ava Faridi,Ava Faridi,Yunxiang Sun,Yutaka Okazaki,Guotao Peng,Jie Gao,Aleksandr Kakinen,Pouya Faridi,Mei Zhao,Ibrahim Javed,Anthony W. Purcell,Thomas P. Davis,Sijie Lin,Reiko Oda,Feng Ding,Pu Chun Ke +15 more
TL;DR: The use of mesoscopic chiral silica nanoribbons against the in vivo amyloidogenesis of human islet ameloid polypeptide (IAPP), the peptide whose aggregation is implicated in type 2 diabetes, results in reduced toxicity.
Journal ArticleDOI
Fluorescence emission originated from the H-aggregated cyanine dye with chiral gemini surfactant assemblies having a narrow absorption band and a remarkably large Stokes shift
Naoya Ryu,Yutaka Okazaki,Yutaka Okazaki,Emilie Pouget,Makoto Takafuji,Shoji Nagaoka,Shoji Nagaoka,Hirotaka Ihara,Reiko Oda +8 more
TL;DR: It is demonstrated that the fluorescence emission that originated from a cyanine dye forming H-aggregates with a narrow absorption band and a remarkably large Stokes shift can be induced by symmetry breaking.
Journal ArticleDOI
Optically Active Perovskite CsPbBr3 Nanocrystals Helically Arranged on Inorganic Silica Nanohelices.
Peizhao Liu,Peizhao Liu,Wei Chen,Yutaka Okazaki,Yann Battie,Lysiane Brocard,Marion Decossas,Emilie Pouget,Peter Müller-Buschbaum,Brice Kauffmann,Shaheen Pathan,Takashi Sagawa,Reiko Oda +12 more
TL;DR: Results indicate that closely packed and helically arranged PNCs on silica nanohelices result in an increase of the optically active properties in the film state.
Journal ArticleDOI
Self-assembled nanostructured metamaterials*
TL;DR: In this paper, a bottom-up fabrication route based on the combination of nanochemistry and the self-assembly methods of colloidal physics is proposed for the large-scale synthesis of complex meta-atoms, as well as for the fabrication of 2D and 3D samples exhibiting meta-properties in visible light.
Journal ArticleDOI
Induced circular dichroism of monoatomic anions: silica-assisted the transfer of chiral environment from molecular assembled nanohelices to halide ions.
Yutaka Okazaki,Naoya Ryu,Thierry Buffeteau,Shaheen Pathan,Shaheen Pathan,Shoji Nagaoka,Emilie Pouget,Sylvain Nlate,Hirotaka Ihara,Reiko Oda +9 more
TL;DR: The first example of induced CD of monoatomic anions is demonstrated using chirally-arranged molecular assemblies of non-chiral cationic gemini surfactants with monoatomal anions stabilized with silica-coating and multi-step transfer of a chiral environment through an in situ chemical reaction via chiralized monoatomics.
