Arjeplog Lapland
To brighten the scope of this blog, here is a new category about various fancy things and thoughts. My best way to end up a scientific meeting (and the rush of the few days before) is to take advantage of it to discover new places and cultures. Following...

Boost your experimental research work
To get the experiments work properly, of course, much time has to be spent, much care has to be taken, BUT this is (generally) not enough. There is a third point, which each expert knows, but mostly no one discusses about : the Experiment’s God needs...

French elections
Mr S., the newly elected French president, publicly affirms that paedophilia and suicide are genetically determined. A positive point is that we no more feel ashamed for our president’s irrelevant opinions. Nevertheless, the next five years are going...

Krabi autrement
In a rush of setting up a new house together with a new experiment, I somehow passed aside writing a few words here about Mark Leger, a.k.a Krabi Autrement. Mark is a French-Thai free-lance guide for people wishing to discover the Krabi province of Thailand...

Turning Plasmonic Antennas on the Right Side: Template Stripping Maximizes Single Molecule Fluorescence Enhancement
Plasmonics is looking for nanogap antennas featuring narrow gap sizes, full accessibility to the plasmonic hotspot and high fabrication throughput. However, the current fabrication methods remain limited to gaps typically around 15-20 nm. Importantly,...
