Microtextured Substrates and Microparticles Used as in Situ Lenses for On-Chip Immunofluorescence Amplification

We propose a concept for enhancing the fluorescent detection signal of on-chip immunoassays by using three-dimensional 3 and 8 mu m size microtextured structures as substrates for the assay, which allows exploitation of a large number of fluorophores withi ...

Conducting polymer microactuators operating in air

Philippe Renaud, Valérie Devaud

We report for the first time on microsized conducting polymer actuators, which operate in air and in liquids. These actuators are potentially useful for a wide range of applications from biotechnology to microrobots. Furthermore, the actuators are fabricat ...

Corneal epithelial cell fate is maintained during repair by Notch1 signaling via the regulation of vitamin A metabolism

Freddy Radtke, Yann Barrandon

Integrity and preservation of a transparent cornea are essential for good vision. The corneal epithelium is stratified and nonkeratinized and is maintained and repaired by corneal stem cells. Here we demonstrate that Notch1 signaling is essential for cell ...

A preliminary study of photodynamic therapy using verteporfin for choroidal neovascularization in pathologic myopia, ocular histoplasmosis syndrome, angioid streaks, and idiopathic causes

Hubert van den Bergh, Guillaume Donati

Objective: To evaluate short-term safety and the effects on visual acuity and fluorescein angiography of single or multiple sessions of photodynamic therapy with verteporfin for choroidal neovascularization (CNV) not related to age-related macular degenera ...

The effect of three-fold astigmatism on measurements of grain boundary volume expansion by high-resolution transmission electron microscopy

Pierre Stadelmann

In the absence of high-order aberrations, the lattice fringe technique should allow measurement of grain boundary rigid-body displacements to accuracies about an order of magnitude better than the point-to-point resolution of the transmission electron micr ...
