Hydrogels and nanogels have emerged as promising materials for biomedical applications owing to their large surface area tunable mechanical chemical properties. Their is well suited bioconjugation, whilst the interior porous network can be utilized transport of valuable biomolecules. The use biocompatible hydrophilic building blocks/linkers preparation hydrogels not only avoids undesired side e...

Abstract The use of natural fibres in fibre-reinforced composites comes with drawbacks. They are highly hydrophilic, leading to high moisture absorption and poor interfacial adhesion matrix-reinforcement bonds. This affects the fibres’ thermal stability as well mechanical properties, hence limiting their wider application. paper reviewed different ways which have been treated improve hydrophobi...

Guided by the recent success of empirical model predicting the folding rates of small two-state folding proteins from the relative contact order (CO) of their native structures, by a theoretical model of protein folding that predicts that logarithm of the folding rate decreases with the protein chain length L as L(2/3), and by the finding that the folding rates of multistate folding proteins st...

The evaporation and dynamics of a multicomponent droplet on a heated chemical patterned surface were presented. Comparing to the evaporation process of a multicomponent droplet on a homogenous surface, it is found that the chemical patterned surface can not only enhance evaporation by elongating the contact line, but also change the evaporation process from three regimes for the homogenous surf...

Tissue engineering has been widely applied in different areas of regenerative medicine, including retinal regeneration. Typically, artificial biopolymers require additional surface modification (e.g. with arginine-glycine-aspartate-containing peptides or adsorption of protein, such as fibronectin), before cell seeding. Here, we describe an alternative approach for scaffold design: the manufactu...

Flax fibres are oftenly used for reinforcing thermoplastic to manufacture biocomposite materials exhibiting numerous advantages such as high mechanical properties, low density and biodegradability. The mechanical properties of a biocomposite material depends on the nature and orientation of the fibres, the nature of the matrix and mainly on the adhesion between fiber and the polymer matrix. The...

New host-guest materials have been prepared by incorporation of a home-made organic probe displaying a pyrene motif and a phosphonate function into a regular amphiphilic copolymer. Using powder X-Ray diffraction, photoluminescence and FT-IR spectroscopy, we have been able to study the non-covalent interactions between the host matrix and the guest molecule in the solid state. Interestingly, we ...

Regulation of angiogenesis involves interactions between vascular endothelial growth factor (VEGF) and components of the extracellular matrix, including fibronectin and heparan sulfate. In the present study, we identified two classes of VEGF binding sites on fibronectin. One was constitutively available whereas the availability of the other was modulated by the conformational state of fibronect...

The objective of the present study was to develop once-daily sustained-release matrix tablets of naproxen, one of the most potent non-steroidal anti-inflammatory agents used in the treatment of arthritic pain. The tablets were prepared by direct compression method using hydrophilic matrix materials like Methocel K4M CR and Methocel K15M CR. The tablets were subjected to measurement of thickness...
