Precision assembly of nanoparticles, top-down meets bottom-up Thursday, 10 November 2016 EPFL researchers have developed a method to place and position hundreds of thousands of nanoparticles very precisely on a one centimeter square surface. This will open new doors in nanotechnologies. Whether it has to do with making pens or building space shuttles, the manufacturing process consists of creating components and then carefully assembling them. But when it comes to infinitely small structures, manipulating and assembling high-performance nanoparticles on a substrate is no mean feat. Researchers in EPFL’s Laboratory of... Read More...
Thousand of nanoantennas to enlighten living cells Friday, 22 May 2015 Large-scale arrays of photonic antennas for nanoscales dynamics in living cell membranes. A recent study carried out in collaboration with researchers of the EPFL and Thomas van Zanten, Mathieu Mivelle, and Carlo Manzo in the Single Molecule Biophotonics group led by ICREA Professor at ICFO Maria Garcia-Parajo, has succeeded in fabricating hundreds of thousands of photonic antennas to measure for the first time the nanoscale dynamics of individual molecules in living cells. This work constitutes a major breakthrough in our ability to... Read More...
Tracing the near field line Monday, 26 January 2015 Single Molecule Dipole Maps the Local Vector Field of an Optical Nano-antenna In a recent study, Anshuman Singh and Gaëtan Calbris of the Molecular NanoPhotonics group led by ICREA Professor at ICFO Niek van Hulst have used single molecule “point” dipoles and a scanning optical antenna to map the 3D vectorial antenna field with 1 nm resolution and to achieve enhanced fluorescence imaging with 40 nm FWHM response. The work, supported by EU project NanoVista, was published in NanoLetters. Read More...
Antenna-in-box platform to enhance single molecule detection Monday, 26 January 2015 Researchers from ICFO and CNRS publish results in Nature Nanotechnology. One of the ultimate goals of molecular biology is to watch how single molecules work at physiological conditions. This involves high local concentrations in the micromolar range, and calls for more than three orders of magnitude shrinking of the detection volume as compared to conventional optical microscopes. Hence, new nanotechnology tools need to be introduced in order to reach ultra-small detection volumes and turn single molecules into bright light sources. Read More...
The balance between adhesion and migration Monday, 26 January 2015 Re-activating adhesion on cells of the immune system in Plos One A recent single molecule study carried out by Kyra Borgman, Thomas van Zanten and Carlo Manzo in the Single Molecule Biophotonics group led by ICREA Professor at ICFO Maria Garcia-Parajo sheds new light on the tight balance between cell adhesion and migration in the immune system. The study reveals that integrin receptors (involved in controlling cell adhesion and migration) can be re-activated in mature dendritic cells and that their lateral mobility on the plasma...
