NIR-emitting and photo-thermal active nanogold as mitochondria-specific probes

Theo Lasser, Jérôme Extermann, Miguel Sison

We report a bioinspired multifunctional albumin derived polypeptide coating comprising grafted poly(ethylene oxide) chains, multiple copies of the HIV TAT derived peptide enabling cellular uptake as well as mitochondria targeting triphenyl-phosphonium (TPP ...

Efficient Inversion of Multiple-Scattering Model for Optical Diffraction Tomography

Michaël Unser, Thanh-An Michel Pham, Emmanuel Emilien Louis Soubies

Optical diffraction tomography relies on solving an inverse scattering problem governed by the wave equation. Classical reconstruction algorithms are based on linear approximations of the forward model (Born or Rytov), which limits their applicability to t ...

Synthesis of superposition shape images by light interacting with layers of lenslets

Jürgen Brugger, Roger Hersch, Thomas Walger, Valentin Flauraud, Théophane Besson

The present invention describes methods and apparatuses for creating superposition shape images by superposed base and revealing layers of lenslet gratings. The superposition shape images form a message recognizable by a human observer or by an image acqui ...

Second-harmonic radiating imaging probes and harmonic holography

Demetri Psaltis, Ye Pu

Compared with other imaging probes such as fluorescent dyes and quantum dots, second-harmonic radiating imaging probes (SHRIMPs) provide a unique ultrafast, coherent optical contrast that is free of photobleaching and emission intermittency. Using the seco ...

Quantitative phase-digital holographic microscopy: a new imaging modality to identify original cellular biomarkers of diseases

Pierre Magistretti, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Pascal Jourdain, Kaspar Rothenfusser

Quantitative phase microscopy (QPM) has recently emerged as a powerful label-free technique in the field of living cell imaging allowing to non-invasively measure with a nanometric axial sensitivity cell structure and dynamics. Since the phase retardation ...

Confocal microscopy via multimode fibers: fluorescence bandwidth

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie

We recently described a method for confocal reflection imaging through fibers, as a way to increase contrast when imaging unstained biological specimens. Using a transmission matrix, focused spots can be created at the distal end of a fiber. The backscatte ...

Variational Phase Imaging Using the Transport-of-Intensity Equation

Michaël Unser, Daniel Sage, Emrah Bostan, Masih Nilchian, Emmanuel Augustin Julien Froustey

We introduce a variational phase retrieval algorithm for the imaging of transparent objects. Our formalism is based on the transport-of-intensity equation (TIE), which relates the phase of an optical field to the variation of its intensity along the direct ...
