A conductive engineered cardiac patch (ECP) can reconstruct the biomimetic regenerative microenvironment of an infarcted myocardium. Direct ink writing (DIW) and 3D printing produce ECP with precisely controlled microarchitectures. However, developing a printed high conductivity flexibility for gapless attachment to conform epicardial geometry remains challenge. Herein, asymmetrical DIW hydroph...

A fundamental understanding of attachment of surface-coated nanoparticles (NPs) is essential to predict the distribution and potential risks of NPs in the environment. Column deposition studies were used to examine the effect of surface-coating hydrophobicity on NP attachment to collector surfaces in mixtures with varying ratios of octadecylichlorosilane (OTS)-coated (hydrophobic) glass beads a...

In this paper we present a monolithic fabrication process for microcapillary sys tems that permits the formation of stable, photo-definable hydrophobic ( ) and hydrophilic ( ) regions on plastic channels. Using this process we have demonstrated a simple injector that uses a hydrophobic patch for cutting and transporting sample drops. Hydrophobic regions are formed by coating the inner walls wit...

Bioinspired functional surfaces are attracting increasing interest in surface engineering, mostly the field of wettability. The Salvinia-effect is a remarkable example superficial air retention and drag force reduction caused by selective chemical coating (super-hydrophobic wax hydrophilic dead cells) peculiar 3D hierarchical morphological structures. replication Salvinia-like patterns at micro...

The growth of Escherichia coli DH5α recombinants producing eicosapentaenoic acid (EPA) (DH5αEPA+) and those not producing EPA (DH5αEPA-) was compared in the presence of hydrophilic or hydrophobic growth inhibitors. The minimal inhibitory concentrations of hydrophilic inhibitors such as reactive oxygen species and antibiotics were higher for DH5αEPA+ than for DH5αEPA-, and vice versa for hydroph...

Block-copolymer amphiphiles have been observed to assemble into vesicles and other morphologies long known for lipids but with remarkably different properties. Coarse-grain molecular dynamics (CG-MD) is used herein to elaborate the structures and properties of diblock copolymer assemblies in water. By varying the hydrophilic/hydrophobic ratio of the copolymer in line with experiment, bilayer, c...

The nature of the equilibrium conformational transition from the denatured state to a four-member alpha-helical bundle was studied employing a dynamic Monte Carlo algorithm in which the model protein chain was confined to a tetrahedral lattice. The model chain was allowed to hunt over all phase space, the target native state was not assumed a priori, and no site-specific interactions were intro...
