Optical nanoantennas can convert propagating light to local fields. The local-field responses can be engineered to exhibit nontrivial features in spatial, spectral and temporal domains. Local-field interferences play a key ...
A Northwestern University research team has developed a new method to conduct spectroscopic nanoscopy, an approach that could help researchers understand more complicated biomolecular interactions and characterize cells and ...
An optical vortex is identified as a phase singularity encircled with helical wavefront, and thanks to its unique properties, including carried orbital angular momentum (OAM) associated with donut-shaped profiles, it has ...
Since Robert Hooke's first description of a cell in Micrographia 350 years ago, microscopy has played an important role in understanding the rules of life.
An international team with researchers from Leiden revealed how a bacterium repurposed an internal system to control its movements. Movement control is very important in host invasion, which can lead to disease. Publication ...
Imaging at the scale of a single molecule has gained much recent research interest in diverse fields of molecular biology, physics and nanotechnology. Researchers have used super-resolution microscopy to access subdiffraction ...
Researchers have used advanced imaging approaches to achieve super-resolution microscopy at unprecedented speeds. The new method should make it possible to capture the details of processes occurring in living cells at speeds ...
Our lives are governed by submicroscopic processes in the nanocosmos. Indeed many natural phenomena begin with a minuscule shift in the states of atoms or molecules, triggered by radiation. One such process has now been elucidated ...
In 1977, Carl Woese et al introduced the three-domain system of biological classification that divides life forms into Archaea, Bacteria and Eukaryotes. This was the first time that the differences between Archaea and Bacteria ...
With ice-cold electron microscopy microbiologists from Leiden gain more insight into how bacteria respond to their environment. Publication in mBio.
