Semi-synthetic, proteolytically degradable polymer hydrogels have proven effective as scaffolds to augment bone and skin regeneration in animals. However, high costs due to expensive peptide building blocks pose a significant hurdle towards broad clinical ...
Measurement of the mechanical behavior of hydrated gels is challenging due to a relatively small elastic modulus and dominant time-dependence compared with traditional engineering materials. Here polyacrylamide gel materials are examined using different te ...
We present a versatile scheme to rationally modulate the hydrolysis rate of ester bonds in hydrophilic polymer networks via adjacent charged amino acids. As soluble model systems, two cysteine-bearing oligopeptides containing either positively charged argi ...
A gel probe equilibrium sampler has been developed to study arsenic (As) geochemistry and sorption behavior in sediment porewater. The gels consist of a hydrated polyacrylamide polymer, which has a 92% water content. Two types of gels were used in this stu ...
Scanning electrochemical microscopy (SECM) was used to image silver-stained proteins on a poly(vinylidene difluoride) membrane. The method is based on measuring the current at a scanning microelectrode in the feedback mode. The electrochemical feedback is ...
In the context of prefractionation methods for proteomics, this work deals mainly with the development of electrophoretic tools for isoelectric focusing of peptides and proteins for the analysis of biological mixtures. In the light of existing devices for ...
Colloid-polymer mixtures can undergo spinodal decomposition into colloid-rich and colloid-poor regions. Gelation results when interconnected colloid-rich regions solidify. We show that this occurs when these regions undergo a glass transition, leading to d ...
In this article the authors present techniques which allow the microfluidic design of alginate microgels with layer composition on a chip. The hydrogel is created by combining two laminar flows of the gel precursor solutions-a calcium solution and an algin ...
Organic–inorganic hybrid materials were prepared using the sol–gel process in order to improve the scratch resistance of poly(methyl methacrylate) (PMMA) substrates. Sol–gel solutions based on tetraethoxysilane and α,ω-triethoxysilane terminated polycaprol ...
Microfluidic devices are increasingly used to perform biological experiments on a single-cell basis. However, long-term stability of cell positions is still an issue. A novel biocompatible method for cell entrapment and release on a microchip is presented. ...
