Photonic Nanojet Array for Fast Detection of Single Nanoparticles in a Flow

Martinus Adela Maria Gijs, Matteo Cornaglia, Hui Yang

We detect by optical microscopy Au and fluorescent nanopartides (NPs) during their motion in water based medium, using an array of dielectric microspheres that are patterned in a microwell array template. The Microspheres act as lenses focusing the light o ...

Challenges and Rewards of the Electrosynthesis of Macroscopic Aligned Carbon Nanotube Array/Conducting Polymer Hybrid Assemblies

László Forró, Endre Horvath, Andrea Pisoni, Péter Krisztián Matus

Hybrid assemblies based on conducting polymers and carbon nanomaterials with organized nanoscale structure are excellent candidates for various application schemes ranging from thermal management to electrochemical energy conversion and storage. In the cas ...

Determination of sub-diffraction-limited organelles and biomolecules using microsphere lenses in combination with fluorescence microscopy

Martinus Adela Maria Gijs, Johan Auwerx, Hui Yang, Norman Lionel Moullan

We propose the use of a high-refractive index glass microsphere in combination with a conventional fluorescence microscope for imaging sub-cellular organelles and biomolecules. The microsphere is placed on a sample that is immersed in water, collects the n ...

Response to "Critical Assessment of the Evidence for Striped Nanoparticles"

Francesco Stellacci, Quy Ong Khac

Stirling et al., (10.1371/journal.pone.0108482) presented an analysis on some of our publications on the formation of stripe-like domains on mixed-ligand coated gold nanoparticles. The authors shed doubts on some of our results however no valid argument is ...

Portable advanced off-axis camera for quantitative phase microscopy

Christian Depeursinge

We propose and experimentally demonstrate a device in which common-path interferometry combined with off-axis holographic geometry is used to realize a digital holographic camera which can be attached to the camera port of a conventional transmission micro ...

Multiple contrast metrics from the measurements of a digital confocal microscope

Michaël Unser, Demetri Psaltis, Alexandre Goy

We describe various methods to process the data collected with a digital confocal microscope (DCM) in order to get more information than what we could get from a conventional confocal system. Different metrics can be extracted from the data collected with ...

3-D PSF fitting for fluorescence microscopy: implementation and localization application

Michaël Unser, Daniel Sage, François Aguet, Hagay Kirshner

Localization microscopy relies on computationally efficient Gaussian approximations of the point spread function for the calculation of fluorophore positions. Theoretical predictions show that under specific experimental conditions, localization accuracy i ...

A universal fluid cell for the imaging of biological specimens in the atomic force microscope

Giovanni Dietler, Sandor Kasas, Giovanni Longo, Livan Bladimir Alonso Sarduy, Charles Roduit

Recently, atomic force microscope (AFM) manufacturers have begun producing instruments specifically designed to image biological specimens. In most instances, they are integrated with an inverted optical microscope, which permits concurrent optical and AFM ...
