What can fluorescence spectroscopy be used for?
What can fluorescence spectroscopy be used for?
Introduction. Fluorescence spectroscopy plays an important function in modern food analysis as can be seen from its wide use in the determination of numerous food components, contaminants, additives, and adulterants.
What source is used for fluorescence spectroscopy?
Light Sources for Fluorescence Spectroscopy Simple light sources such as certain gas discharge lamps (e.g. mercury vapor lamps) can be used for generating ultraviolet light, either with continuous or pulsed emission. One then often requires some kind of optical bandpass filter for restricting the spectral range.
What are the applications of fluorescence in medicine?
Fluorescence spectroscopy is an emerging diagnostic tool for various medical diseases including pre- malignant and malignant lesions. Fluorescence spectroscopy is a noninvasive technique and has been applied successfully for the diagnosis of multisystem cancers with high sensitivity and specificity.
How is fluorescence used in chemistry?
Fluorescence spectroscopy can be used to measure the concentration of a compound because the fluorescence intensity is linearly proportional to the concentration of the fluorescent molecule. Fluorescent molecules can also be used as tags.
How is fluorescence spectroscopy important in medicine?
Fluorescence spectroscopy seems to be promising diagnostic technique with fast and rapid diagnosis ability. Studies indicate high sensitivity and specificity rate which makes Fluorescence spectroscopy an ideal diagnostic tool for medical microbiology field.
Why fluorescence spectroscopy is considered as an important tool in biomedical field explain by giving its applications biomedical field?
How is fluorescence used in forensics?
Fluorescent microscopy techniques have been widely used within forensic science to assist in the visualization of latent fingerprints, identification of GSR and examination of other types of trace evidence.
Why fluorescence is important in analytical work?
Fluorescence is an important investigational tool in many areas of analytical science, due to its high sensitivity and selectivity. It can be used to investigate real-time structure and dynamics both in solution state and under microscopes, particularly for bio-molecular systems.
How does fluorescence spectroscopy work?
Fluorescence spectroscopy uses a beam of light that excites the electrons in molecules of certain compounds, and causes them to emit light. That light is directed towards a filter and onto a detector for measurement and identification of the molecule or changes in the molecule.
What is fluorescein sodium used for?
Fluorescein sodium, the sodium salt of fluorescein, is used extensively as a diagnostic tool in the field of ophthalmology and optometry, where topical fluorescein is used in the diagnosis of corneal abrasions, corneal ulcers and herpetic corneal infections.
