Modulation of Fluorescence Signals from Biomolecules along Nanowires Due to Interaction of Light with Oriented Nanostructures

Anna Fontcuberta i Morral, Esther Alarcon Llado

High aspect ratio nanostructures have gained increasing interest as highly sensitive platforms for biosensing. Here, well-defined biofunctionalized vertical indium arsenide nanowires are used to map the interaction of light with nanowires depending on thei ...

Spectral prediction model for color prints on paper with fluorescent additives

Roger Hersch

I propose a model for predicting the total reflectance of color halftones printed on paper incorporating fluorescent brighteners. The total reflectance is modeled as the additive superposition of the relative fluorescent emission and the pure reflectance o ...

Printing color images visible under uv light on security documents and valuable articles

Roger Hersch, Sylvain Chosson, Philipp Donzé

In the present invention, we propose a method of creating fluorescent color images visible under UV light. It relies on the new colorants that can be achieved by superposing ink dots, possibly at a reduced size, in order to avoid quenching effects. It also ...

Color images visible under UV light

Roger Hersch, Sylvain Chosson, Philipp Donzé

The present contribution aims at creating color images printed with fluorescent inks that are only visible under UV light. The considered fluorescent inks absorb light in the UV wavelength range and reemit part of it in the visible wavelength range. In con ...

Clinical imaging fluorescence apparatus for the endoscopic photodetection of early cancers by use of Photofrin II

Hubert van den Bergh, Christian Depeursinge, Georges Wagnières, André Châtelain, André Studzinski

A fluorescence imaging device applied to the detection of early cancer is described. The app. is based on the imaging of laser-induced fluorescence of a dye that localizes in a tumor with a higher concn. than in the surrounding normal tissue after i.v. inj ...
