The aim of the paper was to demonstrate the current state of research and development in the field of nanocelluloses on the basis of selected examples. The extraordinary supramolecular nanofiber network structure and the resulting valuable properties have led to a real challenge and extensive global activity. It is the intention of this work to broaden knowledge in this subject area... [Pg.88]

The second chapter by Dieter Klemm, Dieter Schumann, Hans-Peter Schmauder, and coworkers focuses on the recent knowledge of cellulosics characterized by a property-determining supramolecular nanofiber structure. Topics in this interdisciplinary contribution are the types of nanocelluloses and their use in technical membranes and composites as well as in the development of medical devices, in veterinary medicine, and in cosmetics.

A supramolecular hydrogel underwent a reversible gel-sol transformation that was formed by adding 9,10-dimethoxy-2-anthracenesulfonic acid to an aqueous dispersion of a cationic amphiphile, (I), as was previously prepared by the author [1]. The gel had a network with a bilayer-membrane and a nanofiber... [Pg.257]

In addition to the uses above, the elaborate utilization of hydrophobic nanofiber domains in the supramolecular hydrogel allowed more selective discrimination of the Zn-Dpa-based chemosensors among various phosphate... [Pg.120]

Peptides composed of various coded and noncoded amino acid residues self-assemble to form various types of supramolecular architectures, including supramolecular helices and sheets, nanotubes, nanorods, nanovesicles, and nanofibers. The higher-order self-assembly of supramolecular (3-sheets or supramolecular helices composed of short synthetic acyclic peptides leads to the formation of amyloid-like fibrils. Synthetic cyclic peptides were used in supramolecular chemistry as molecular scaffolding for artificial receptors, so as to host various chiral and achiral ions and other small neutral substrates. Cyclic peptides also self-assemble like their acyclic counterparts to form supramolecular structures, including hollow nanotubes. Self-assembling cyclic peptides can be served as artificial ion channels, and some of them exhibit potential antimicrobial activities against drug-resistant bacteria. [Pg.42]

Peptide amphiphUes (PAs) are well known to form functirmal supramolecular materials [68]. PAs consists of (i) a short hydrophobic domain, often an alkyl chain, linked to (ii) an oligopeptide that induces and guides self-assembly by the formatiOTi of P-sheets, and (iii) an oligopeptide containing a bioactive domain [69]. In water, these molecules assemble into high-aspect-ratio nanofibers, which entangle and... [Pg.261]
