An unprecedented three-level hierarchical entangled system was synthesized. The basic helical ribbons of the complex were entangled into 2D layers by self-penetration based on 1D → 2D polycatenation; a pair of layers interpenetrated, and crosslinked to construct the second self-penetrated bilayers which were further polycatenated into the final 3D entangled array.

Drug release from collagen matrices is in most cases governed by diffusion from swollen matrices but also enzymatic matrix degradation or hydrophobic drug/collagen interactions may contribute. To reduce water uptake and to prolong the release, insoluble collagen matrices have been chemically or dehydrothermally crosslinked. Assuming Fickian diffusion a one-dimensional model was developed and te...

Nanoprecipitation of miglyol into droplets surrounded by a functional glycopolymer generates nanocapsules of biointerest. Fluorophores are trapped in situ or post-grafted onto the crosslinked polymer shell for efficient imaging. The resulting colloids induce aggregation of bacteria through strong specific interactions and promote their facile removal.

When isotopically labelled photo-crosslinking amino acids are site-specifically incorporated into proteins, in combination with the corresponding non-labeled analogue, cross-linked tryptic peptides are easily identified in mass spectra via characteristic "doublet" patterns.

Emulsions stabilized by enzyme-nanoparticle (NP) complexes were used to fabricate robust biocatalytic scaffolds after core solidification via crosslinking. These biocatalysts feature ease of formation, high retention of enzymatic activity and reusability.

We describe a gold nanoparticle based assay that can rapidly determine the crosslinking of DNA duplexes by ligands. Such compounds have potential in targeting highly compacted DNA such as that found in the nucleosome.

In this work we examine layer fluctuations in a smectic elastomer with quenched random disorder induced by crosslinks. The system is analyzed in a continuum model and crosslinks are introduced as a random field in a macroscopic picture. In the case of small deformations and replica symmetry the intensity profile for x-ray scattering along the layer normal was determined for layer displacements ...

A dynamic covalent crosslinking approach is used to crosslink supramolecular peptide gels. This novel approach facilitates tuning viscoelastic properties of the gel and enhances mechanical stability (storage modulus exceeding 10(5) Pa) of the peptide gels.

The output colour distributions from red, green and blue (RGB) LEDs mixed with cross linked PMMA micro particle doped PMMA mixing rods is compared to output from a plain PMMA mixing rod. Distinctive patterns with clear colour separation result with the undoped rod. These are homogenised by our mixers, resulting in white light. Light output has been photographed, measured and computer simulated ...
