Exploiting biocatalysis in peptide self‐assembly
Peptide Science, 2010AbstractThis review article covers recent developments in the use of enzyme‐catalyzed reactions to control molecular self‐assembly (SA), an area that merges the advantages of biocatalysis with soft materials self‐assembly. This approach is attractive because it combines biological (chemo‐, regio‐, and enantio‐) selectivity with the versatility of ...

Self-assembly peptide prevents blood loss
Nanomedicine: Nanotechnology, Biology and Medicine, 2006Recently, researchers from the Massachusetts Institute of Technology and the University of Hong Kong discovered a new peptide that immediately stopped bleeding at the surgical site. Nanohemostat solution stops blood flow in less than 10 seconds in the cutting site of brain, spinal cord, femoral artery, and liver. Although the actual mechanism of action

Self-Assembled Peptide Nanofibers
2009Molecular self-assembly is a powerful approach being explored for novel supramolecular nanostructures and bio-inspired nanomaterials. In this article, we focus on recent research concerning the self-assembly of de novo designed artificial peptides and peptidomimetics into nanofiber structures, specifically towards developing a new class of soft ...

Self-Assembly of Surfactant-like Peptides
Langmuir, 2007Inspired by recent work describing surfactant-like peptides, we have carried out a systematic study on peptides with the underlying composition of V6D2, altering the absolute sequence to determine the importance of the surfactant-like structure. All of the peptides examined here formed self-assembled structures in water.

Tunable Self-Assembled Peptide Amphiphile Nanostructures
Langmuir, 2012Peptide amphiphiles are capable of self-assembly into a diverse array of nanostructures including ribbons, tubes, and vesicles. However, the ability to select the morphology of the resulting structure is not well developed. We examined the influence of systematic changes in the number and type of hydrophobic and hydrophilic amino acids on the self ...

Photolytic Control of Peptide Self-Assembly
Journal of the American Chemical Society, 2003Herein, we present a methodology that allows for the temporal control of fibrillization of amyloidogenic peptides. This general approach implements a photolabile linker that connects the amyloidogenic peptide to a fibril-inhibitory unit, in this case, a pentamer of amino acids modified with the solubilizing N,N-dimethylethylenediamine (DMDA) units ...

Self-assembled peptide hydrogels [PDF]
, 2011 The use of low-molecular weight peptide-based hydrogelators (LMWGs) for the immobilisation of enzymes is presented in this thesis. Low-molecular weight hydrogelators are a class of materials which are highly suitable for increasing enzyme lifetimes as they create a suitable biomimetic environment.
