PEAR: setting nano-imaging in motion
Ever since the Abbe diffraction limit of conventional microscopy has been surpassed, super-resolution techniques have been diving ever deeper into the most miniscule details of molecular structures. We spoke with Prof. Dominic Zerulla, whose company PEARlabs is developing an imaging technique that sets out to push the boundaries once more – by looking at in-vivo nano-scale processes in motion.

New low-cost solution for virus-scale microscopy
Using an ordinary light microscope, engineers at the Massachusetts Institute of Technology (MIT) have devised a technique for imaging biological samples with accuracy at the scale of 10 nanometers — which should enable them to image viruses and potentially even single biomolecules, the researchers say. The new technique builds on expansion microscopy, an approach that involves embedding…

Multimodal imaging to detect cancerous cells faster and more accurately
Improving the detection of cancerous cells during surgery – this is the goal of the European research project CARMEN. The research institutes Laser Zentrum Hannover e.V. (LZH) from Germany and Multitel asbl from Belgium work together with companies from both countries, JenLab GmbH, Deltatec, and LaserSpec, to develop a novel, compact and multimodal imaging system. This could even allow the…

Researchers develop the world’s smallest ultrasound detector
Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world’s smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as…
