Heart-on-a-Chip: An Investigation of the Influence of Static and Perfusion Conditions on Cardiac (H9C2) Cell Proliferation, Morphology, and Alignment

Philippe Renaud

Lab-on-a-chip systems are increasingly used as tools for cultures and investigation of cardiac cells. In this article, we present how the geometry of microsystems and microenvironmental conditions (static and perfusion) influence the proliferation, morphol ...

Transparent and Robust Silica Coatings with Dual Range Porosity for Enzyme-Based Optical Biosensing

Heinrich Hofmann, Oswaldo Javier Pérez Anguiano, Bernard Wenger, Raphaël Pugin, Emmanuel Scolan

Hierarchically porous transparent silica coatings combine large specific surface area with enhanced pore accessibility for optical biosensing. This paper describes a versatile approach to fabricate optically transparent silica coatings with multiscale poro ...

Wiley-Blackwell2017

Passively fed ionic liquid electrospray sources are capable of efficiently emitting a variety of ion beams with promising applications to spacecraft propulsion and as focused ion beams. Practical devices will require integrated or coupled ionic liquid rese ...

Microfluidic chip for monitoring Ca2+ transport through a confluent layer of intestinal cells

Martinus Gijs, Paolo Silacci, Hüseyin Cumhur Tekin, Josias Basil Wacker, Christine Ruffert, Guy Vergères

The absorption of dietary calcium through the intestinal barrier is essential for maintaining health in general and especially of the bone system. We propose a microfluidic model that studies free calcium (Ca2+) transport through a confluent monolayer of C ...

A microfluidic process for on-chip formation of assemblies of oxide nanoparticles

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker, Danut Necula

We report the continuous growth of spherical assemblies of silica and titania nanoparticles, which were pre-activated to produce hydroxyl/ peroxy groups on their surface, by flowing a colloid-in-dioctyl phthalate emulsion into a polydimethylsiloxane microf ...

Royal Soc Chemistry2014

The research areas of tissue engineering and drug development have displayed increased interest in organ-on-a-chip studies, in which physiologically or pathologically relevant tissues can be engineered to test pharmaceutical candidates. Microfluidic techno ...

Opportunities for high-pressure microfluidics in biomedical applications

Ata Tuna Ciftlik

Pressure lies at the basis of operation of most microfluidic systems, and is a determinant factor in the extent of miniaturization and in limiting the throughput and time constant of the microfluidic assays. Despite the apparent importance given to fluidic ...

Numerical Simulation of Porosity in Cements

Karen Scrivener, Shashank Bishnoi, Quang Huy Do

The pores in cementitious materials, their sizes and connectivity have an important influence on the durability of concrete. Several microstructural models have been developed to simulate the three-dimensional pore network in cement pastes. In this article ...

Hydrogel Microfluidics to Control Stem Cell Fate

Steffen Cosson

Biomolecular signaling is of utmost importance in governing many biological processes such as morphogenesis during tissue development where biomolecules regulate key cell-fate decisions. In vivo, these factors are presented in a spatiotemporally tightly co ...
