Redefining Fluorescence Lifetime Imaging Microscopy Image Credit: Micha Weber/Shutterstock.com Conventional fluorescence lifetime imaging microscopy (FLIM) relies on point-to-point scanning of a tightly focused illumination beam across the sample to form an image, impeding rapid imaging. To overcome this limitation, researchers from Japan and the USA have developed scan-less wide-field imaging methods that can image fluorescence lifetime at unprecedented speeds and capture ultrafast transient phenomena relevant to biomedical research and life sciences. FLIM is an imaging tech...

What is Confocal Fluorescence Microscopy? Confocal fluorescence microscopy is a commonly used optical imaging method in biology, combining fluorescence imaging with confocal microscopy for increased optical resolution. This article will discuss the principles of fluorescence and confocal microscopes, and describe the stages of fluorophore selection and sample preparation.

Fluorescence is the process by which a photon is absorbed, and another of slightly lower energy, and therefore longer wavelength, is subsequently emitted. Un...

Scientists develop new method for fluorescence microscopy ANI | Updated: Jan 03, 2021 11:31 IST Tokushima [Japan], January 3 (ANI): Scientists from the Institute of Post-Led Photonics, Tokushima University develop a fluorescence 'lifetime' microscopy technique that uses frequency combs and no mechanical parts to observe dynamic biological phenomena. Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light with...

The research team has developed a novel approach to acquire fluorescence lifetime images without necessitating mechanical scanning.

Malaria. >> you said something aebout fluorescent light. why is that an improvement? >> sure. fluorescence microscopy has been shown to be faster to use, better has finding t.b. and easier to use. you get an image that's multicolored and you have to really go through an image to find a disease or pathogen with the current process. but with this, it's a black image. when you have a positive result, you get bright glowing dots therefrom the tuberculosis or the disease in question, you know right away that's what you're looking at. it's faster and easier. and it's a very sophisticated technology ...
