Visualising the Invisible: Active Sites in Antibacterial Nanomaterials

Fluorescence lifetime microscopy has great potential to systematically enhance the effectivenes of antibacterial nanomaterials

20-Dec-2024 - Interest in antibacterial nanomaterials has surged due to the growing threat of antibiotic-resistant microbes. A particularly promising strategy involves the use of nanomaterials that generate reactive oxygen species upon exposure to light, effectively combating microorganisms. However, a key ...

Microscopy: Overcoming the traditional resolution limit for the fast co-tracking of molecules

Researchers have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale

16-Feb-2024 - Processes within our bodies are characterized by the interplay of various biomolecules such as proteins and DNA. These processes occur on a scale often within a range of just a few nanometers. Consequently, they cannot be observed with fluorescence microscopy, which has a resolution limit of ...

Biologists make living sperm glow

16-Jan-2020 - By applying a novel method, biologists at TU Dresden have successfully analysed the metabolism of intact tissues of the fruit fly using a label-free microscopy technique. They used the natural fluorescence of certain metabolic molecules and found that sperm, compared to other tissues, are highly ...

Microscopy: Nine at one blow

05-Feb-2016 - Advance in biomedical imaging: The University of Würzburg's Biocenter has enhanced fluorescence microscopy to label and visualise up to nine different cell structures simultaneously. Fluorescence microscopy allows researchers to visualise biomolecules in cells. They label the molecules using ...

Rice University researchers optimize photoluminescent probes to study DNA and more

10-Sep-2012 - Sorting good data from bad is critical when analyzing microscopic structures like cells and their contents, according to researchers at Rice University. The trick is to find the right window of time through which to look.A new paper by the Rice lab of Angel Martí, an assistant professor of ...
