Three different microscope setups have been used for the study: Laser Induced Fluorescence (LIF) microscopy, Raman microscopy and coherent anti-Stokes Raman Scattering (CARS) microscopy. https://www.leica-microsystems.com/science-lab/chemical-basis-for-alteration-of-an-intraocular-lens-using-a-femtosecond-laser/ Sun, 27 May 2018 22:00:00 +0000 https://www.leica-microsystems.com/13935 Fluorescence Microscopy Video Talk by Roger Tsien: Fluorescent Proteins Live cell imaging has been revolutionized by the discovery of the green fluorescent protein (GFP). This lecture covers the history of GFP, how it folds and becomes fluorescent, how it has been mutated to produce additional colors (blue, cyan, yellow), and the discovery of red fluorescent proteins from corals. It also covers novel photoswitchable and photoactivatible fluorescent proteins, whose color can be changed by light, and new infrared fluorescent proteins. https://www.leica-microsystems.com/science-lab/video-talk-by-roger-tsien-fluorescent-proteins/ Wed, 07 Oct 2015 16:55:00 +0000 PhD Roger Y. Tsien https://www.leica-microsystems.com/5726 EM Sample Preparation A Word on Cathodoluminescence Cathodoluminescence microanalysis is an emerging technique that is fast gaining popularity in the world of materials science. CL is a light emission phenomena resulting from the electron beam excitation of a luminescent material. https://www.leica-microsystems.com/science-lab/a-word-on-cathodoluminescence/ Sun, 03 Feb 2013 23:00:00 +0000 Cathy Johnson https://www.leica-microsystems.com/5890 Fluorescence Microscopy Basics in Microscopy Basic Principles of Luminescence There are a lot of light-emitting processes occurring in nature. Luminescence is an umbrella term for those kinds of events where light emission is not the result of high temperatures. This article depicts the different forms of luminescences and goes into detail in the case of fluorescence. Relevant technical terms describing a fluorochrome, like quenching, bleaching or quantum yield, are explained in the second part of the article to give detailed insights into basic characteristics of fluorescent molecules. https://www.leica-microsystems.com/science-lab/basic-principles-of-luminescence/ Mon, 09 Apr 2012 22:00:00 +0000 Dr. Christoph Greb https://www.leica-microsystems.com/4182 Fluorescence Microscopy Basics in Microscopy An Introduction to Fluorescence Fluorescence is widely used in microscopy and an important tool for observing the distribution of specific molecules. Most molecules in cells do not fluoresce. They therefore have to be marked with fluorescing molecules called fluorochromes. https://www.leica-microsystems.com/science-lab/an-introduction-to-fluorescence/ Tue, 31 May 2011 13:29:00 +0000 Wymke Ockenga
