Biodegradable Nanoparticles of Partially Methylated Fungal Poly(beta-L-malic acid) as a Novel Protei

Biodegradable Nanoparticles of Partially Methylated Fungal Poly(beta-L-malic acid) as a Novel Protein Delivery Carrier.
The preparation of nanoparticles from 75% methylated poly(beta-L-malic acid) is described. Their degradation in aqueous environments was examined and the influence of pH and lipase on the rate of hydrolysis was evaluated. Six proteins were used to estimate the […]

Chemical Conjugation of Linear and Cyclic RGD Moieties to a Recombinant Elastin-Mimetic Polypeptide

Chemical Conjugation of Linear and Cyclic RGD Moieties to a Recombinant Elastin-Mimetic Polypeptide - A Versatile Approach towards Bioactive Protein Hydrogels.
An elastin-mimetic polypeptide, (EMM)(7), with the amino-acid sequence GRDPSS [VPGVG VPGKG VPGVG VPGVG VPGEG VPGIG](7) was used for chemical conjugation of various integrin ligands (RGD peptides) to prepare bioactive hydrogels. The chemical […]

Mesoporous Carbon Materials: Synthesis and Modification.

Mesoporous Carbon Materials: Synthesis and Modification.
Porous carbon materials are of interest in many applications because of their high surface area and physicochemical properties. Conventional syntheses can only produce randomly porous materials, with little control over the pore-size distributions, let alone mesostructures. Recent breakthroughs in the preparation of other porous materials have resulted […]
