Biofilm morphogenesis on soft hydrogels

Bacteria often colonize their environment in the form of surface attached multicellular communities called biofilms. Biofilms grow from surface-attached cells that undergo division while self-embedding in a viscoelastic matrix. Biofilms grow at the surface ...

Label-Free Cytotoxicity Screening Assay by Digital Holographic Microscopy

Pierre Magistretti, Christian Depeursinge, Gerardo Turcatti, Benjamin Rappaz, Marc Chambon, Jonas Kühn, Etienne Shaffer, Jérôme Parent, Julien Mena

We introduce a label-free technology based on digital holographic microscopy (DHM) with applicability for screening by imaging, and we demonstrate its capability for cytotoxicity assessment using mammalian living cells. For this first high content screenin ...

From Particles to Pillars : Droplet Microfluidics Applied to the Synthesis and Assembly of Functional Metal-Oxide Nanoparticles

Josias Basil Wacker

Metal oxide nanoparticles and their applications (e.g. in nano-electronics, nano-optics or drug delivery) have seen a growing interest in the past decades. Traditional procedures to synthesize, functionalize and integrate nanoparticles in devices mostly ha ...

An agarose-based microfluidic platform with a gradient buffer for 3D chemotaxis studies

Melody Swartz, Ulrike Haessler, Mingming Wu

The current state-of-art in 3D microfluidic chemotaxis device (mu FCD) is limited by the inherent coupling of the fluid flow and chemical concentration gradients. Here, we present an agarose-based 3D mu FCD that decouples these two important parameters, in ...

Synthesis of a C-linked disaccharide analogue of the Thomsen Friedenreich (TF)-epitope a-O-conjugated to L-serine and formation of a cluster as potential anticancer vaccine

Loay Awad

Cell surface glycoproteins and glycolipids are responsible for cellular recognition processes. Vaccination is the procedure whereby the immune system is induced to create antibodies against a foreign molecule involved in disease or viral infection. In many ...

Gentle cell trapping and release on a microfluidic chip by in situ alginate hydrogel formation

Philippe Renaud, Thomas Michael Braschler, Lynda Metref

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. ...
