Morphology‐Dependent Cell Imaging by Using a Self‐Assembled Diacetylene Peptide Amphiphile

17.10.2017 | Carsten Schmuck, Hao Jiang, Xiao-Yu Hu, Stefanie Schlesiger, Mao Li, Elio Zellermann, Shirley Knauer; Hao Jiang, Xia ..., Angewandte Chemie, 2017

Abstract Herein, a novel cationic peptide gemini amphiphile containing diacetylene motifs (DA2P) is presented, which self‐assembles into novel tadpole‐ and bola‐shaped nanostructures at low concentrations and nanofibers at higher concentrations. Interestingly, the DA2P assemblies can be ...

Copper(II)–Thymine Coordination Polymer Nanoribbons as Potential Oligonucleotide Nanocarriers

09.12.2016 | Verónica G. Vegas, Romina Lorca, Ana Latorre, Khaled Hassanein, Carlos J. Gómez‐García, Oscar Castillo, Álvaro Somoz ..., Angewandte Chemie, 2016

Abstract The direct reaction between copper nitrate, thymine‐1‐acetic acid, and 4,4′‐bipyridine in water leads to the formation of a blue colloid comprising uniform crystalline nanoribbons (length >1 μm; width ca. 150–185 nm; diameter ca. 15–60 nm) of a coordination polymer. The polymer ...

Role of Achiral Nucleobases in Multicomponent Chiral Self‐Assembly: Purine‐Triggered Helix and Chirality Transfer

03.11.2016 | Ming Deng, Li Zhang, Yuqian Jiang, Minghua Liu, Angewandte Chemie, 2016

Abstract Chiral self‐assembly is a basic process in biological systems, where many chiral biomolecules such as amino acids and sugars play important roles. Achiral nucleobases usually covalently bond to saccharides and play a significant role in the formation of the double helix structure. ...
