New microscopy method resolves fluorescent molecules with resolution at the nanometer scale

22-Mar-2021

Scientists working with Stefan Hell at the Max Planck Institute (MPI) for Biophysical Chemistry in Göttingen and the Heidelberg-based MPI for Medical Research have developed another light microscopy method, called MINSTED, which resolves fluorescently labeled details with molecular sharpness. ...

Fluorescence microscopy at highest spatial and temporal resolution

Researchers simplify the MINFLUX microscope and have succeeded in differentiating molecules that are extremely close together and tracking their dynamics.

21-Jan-2021

Only a few years ago, an ostensibly fundamental resolution limit in optical microscopy was superseded - a breakthrough which in 2014 led to the Nobel Prize in Chemistry for super-resolution microscopy. Since then, there has been another quantum leap in this area, which has further reduced the ...

Chemists produce simple fluorescent surfactants

Compounds show promise for use in medicine, manufacturing

07-Aug-2019

Laboratories use surfactants to separate things, and fluorescent dyes to see things. Rice University chemists have combined the two to simplify life for scientists everywhere. The Wiess School of Natural Sciences lab of chemist Angel Martí introduced a lineup of eight fluorescent surfactants in ...

Testing chemicals without animal testing on rodents

Replacement method with locusts to test whether chemicals cause neurological developmental disorders in children

11-Jul-2019

In recent years, the number of neurological developmental disorders in children has increased. Epidemiological data suggest that lifestyle factors and chemicals used in our environment contribute to this. Scientists from the Institute of Physiology and Cell Biology at the University of Veterinary ...

A super resolution view of chemical reactions

14-Feb-2018

Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have demonstrated, using a super resolution microscopic technique, how to follow chemical reactions taking place in very small volumes. The method of analysis developed by the Warsaw physicists in collaboration ...

Piecework at the nano assembly line

Fast computer control for molecular machines

22-Jan-2018

Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line ...

Light can improve perovskite solar cell performance

02-May-2017

EPFL scientists show how light affects perovskite film formation in solar cells, which is a critical factor in using them for cost-effective and energy-efficient photovoltaics. Perovskites are materials of immense interest in solar energy technology lately, as they promise to bring down the cost ...

Beating the limits of the light microscope, one photon at a time

30-May-2016

The world's most advanced light microscopes allow us to see single molecules, proteins, viruses and other very small biological structures. But even the best microscopes have their limits. Colorado State University scientists are pushing the limits of a technique called super-resolution ...

More light on cancer

Scientists created nanoparticles to highlight cancer cells

23-May-2016

The group of Russian and French researchers, with the participation of scientists from the Lomonosov Moscow State University, has succeeded to synthesize nanoparticles of ultrapure silicon, which exhibited the property of efficient photoluminescence, i.e., secondary light emission after ...

New design tool for metamaterials

Berkeley Lab study shows how to predict metamaterial nonlinear optical properties

11-Feb-2015

Metamaterials - artificial nanostructures engineered with electromagnetic properties not found in nature - offer tantalizing future prospects such as high resolution optical microscopes and superfast optical computers. To realize the vast potential of metamaterials, however, scientists will need ...
