Optical fibres can 'feel' the materials around them

Optical fibres can 'feel' the materials around them
EPFL researchers have developed an optical fibre capable of detecting what sort of material or liquid they have come into contact with. Their research has been published in Nature Communications. In recent years optical fibres have served as sensors to detect changes in temperature, like a thermometer, and pressure, like an artificial nerve. This technique is particularly useful in structures such as bridges and gas pipelines.

Super-resolution microscopy in space and time

Super-resolution microscopy in space and time
Super-resolution microscopy is a technique that can “see” beyond the diffraction of light, providing unprecedented views of cells and their interior structures and organelles. The technique has garnered increasing interest recently, especially since its developers won the Nobel Prize in Chemistry in 2014. But super-resolution microscopy comes with a big limitation: it only offers spatial resolution.

Miniaturising frequency combs

Miniaturising frequency combs
EPFL scientists have found a way to miniaturise frequency combs, realising a new step toward miniaturisation of such tools. Their device can measure light oscillations with a precision of 12 digits. A compact, precision tool for counting and tracking laser frequencies may improve atomic clocks and optical data transmission devices. However, light waves oscillate hundreds of trillions of times per second, a frequency that is impossible to measure directly.

Train windows that combine mobile reception and thermal insulation

Train windows that combine mobile reception and thermal insulation
Researchers from EPFL have developed a type of glass that offers excellent energy efficiency and lets mobile telephone signals through. And by teaming up with Swiss manufacturers, they have produced innovative windows. Railway company BLS is about to install them on some of its trains in order to improve energy efficiency.

High-resolution imaging reveals bacterial toxins

Many bacteria use specialised toxins to attack and infect other cells. Scientists at EPFL and the University of Bern have now modeled a major such toxin with unprecedented resolution, uncovering the way it works step-by-step. In order to infect other cells, many bacteria secrete a type of toxin that punctures the membrane of the target cell and form a pore; as a result, the cell dies.

Lasers enable tissue engineering

Lasers enable tissue engineering
Two EPFL scientists have developed a method that uses lasers to carve out paths inside biocompatible gels to locally influence cell function and promote tissue formation. The work is published in Advanced Materials. Working at EPFL's Institute of Bioengineering, Matthias Lütolf and his PhD student Nathalie Brandenberg have developed a method that uses a laser to cut 3D pathways and networks for cells inside a hydrogel scaffold that matches their natural environment.
