Thrombosis efficacy induced by photodynamic therapy using different photosensitizers

Various human pathologies, such as cancers or, notably, exudative age-related macular degeneration (AMD), are characterized by an abnormal vascular proliferation (angiogenesis), which in the case of this type of AMD, can rapidly lead to blindness if no cou ...

Assembly of Metal Nanoparticles into Nanogaps

Francesco Stellacci

The directed assembly of nanoparticles and nanoscale materials onto specific locations of a surface is one of the major challenges in nanotechnology. Here we present a simple and scalable method and model for the assembly of nanoparticles in between electr ...

Sol-gel deposition and characterization of low refractive index nanocomposite Mg:F:Si:O thin films for solar and protective coatings

Jean-Louis Scartezzini, Christian Roecker, Josef Andreas Schuler, Estelle De Chambrier, Dipanwita Dutta

Coatings for thermal solar energy conversion have to be abrasion-resistant, stable at elevated temperatures, and often have to protect the substrate against corrosion. Due to the conditions of refractive index matching between the substrate and the ambient ...

Directed assembling of gold nanoparticles using Van der Waals interactions

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

In the last past years, many promising applications of nanoparticles in quantum electronics such as nanocrystal memories, chemical sensors or nanodevices based on single electron tunneling and Coulomb blockade effects have attracted much attention. Nanopar ...

Photoluminescence characterization of localized 2D-layers of few-nanocrystals electronic devices

Marc Antonius Friedrich van den Boogaart

Photoluminescence (PL) spectroscopy has been demonstrated as a suitable technique to characterize Si nanocrystal-based non-volatile memory devices (Carrada et al. APL 2005). These are formed by a single plane of Si nanocrystals (NCs) buried in the gate oxi ...

Photoluminescence characterization of few-nanocrystals electronic devices

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

Photoluminescence (PL) spectroscopy is demonstrated as a suitable technique to characterize silicon nanocrystals (Si-NCs)-based nonvolatile memory devices. The 2D array of Si-NCs forming the floating gate is obtained by low-energy ion implantation in thin ...

A sensitive in vivo model for quantifying interstitial convective transport of injected macromolecules and nanoparticles

Melody Swartz, Sai Reddy

Effective interstitial transport of particles is necessary for injected drug/diagnostic agents to reach the intended target; however, quantitative methods to estimate such transport parameters are lacking. In this study we develop an in vivo model for eval ...

Enhanced magnetic field sensitivity of spin-dependent transport in cluster-assembled metallic nanostructures

Jean-Philippe Ansermet, Jean-Pierre Abid, Santiago Serrano Guisan, Giulia Di Domenicantonio

The emerging field of spintronics explores the many possibilities offered by the prospect of using the spin of the electrons for fast, nanosized electronic devices. The effect of magnetization acting on a current is the essence of giant or tunnel magnetore ...

Fabrication and functionalization of nanochannels by electron-beam-induced silicon oxide deposition

Jürgen Brugger, Horst Vogel, Christian Santschi, Christophe Danelon

We report on the fabrication and electrical characterization of functionalized solid-state nanopores in low stress silicon nitride membranes. First, a pore of approximately 50 nm diameter was drilled using a focused ion beam technique, followed by the loca ...

Nanocomposites based on luminescent colloidal nanocrystals in polymers: new opportunities for micro and nano fabrication

Jürgen Brugger, Vahid Fakhfouri

In recent years a wide range of materials including metals, semiconductors and metal oxides have been synthesized with nanometer dimensions. In particular II–VI semiconductor nanocrystals (NCs) are receiving considerable attention for fundamental studies a ...
