Photobleaching 뜻
WebHowever, reducing light intensity can also reduce emission signal. A careful balance must be found so that image quality is not compromised. Reducing time exposure to light sources also reduces photobleaching as this also decreases the frequency of excitation-emission cycles. Fluorogenic molecules must be stored away from light sources as much ...

WebPhotobleaching is the irreversible destruction of a fluorophore under the influence of light. FPbase catalogs efforts that have been made to quantify the photostability of various fluorescent proteins. Typically, these report the time that it takes for the emission intensity of a fluorescent protein to reach half of its initial value, or it may ... WebFeb 20, 2024 · Photochemical stability is one of the most important parameters that determine the usefulness of organic dyes in different applications. This Review addresses key factors that determine the dye photostability. It is shown that photodegradation can follow different oxygen-dependent and oxygen-independent mechanisms and may involve …
In optics, photobleaching (sometimes termed fading) is the photochemical alteration of a dye or a fluorophore molecule such that it is permanently unable to fluoresce. This is caused by cleaving of covalent bonds or non-specific reactions between the fluorophore and surrounding molecules. Such irreversible … See more • Ozone depletion See more • Introduction to Optical Microscopy an article about photobleaching • Viegas MS; Martins TC; Seco F; do Carmo A (2007).

광표백(光漂白, 영어: photobleaching)은 광학에서 영구적으로 형광을 발할 수 없게 된 염료 또는 형광 색소의 광화학적 변화이다. 이것은 형광 색소와 주변 분자 사이의 공유 결합의 절단 또는 비특이적 반응으로 인해 일어난다. 공유 결합에서 이러한 비가역적 변형은 형광 색소의 단일항 상태에서 삼중항 상태로의 전이로 인해 발생한다. 완전한 표백을 위한 여기 주기의 수는 다양하다. 현미경 관찰시 광표백은 형광 분자의 관찰을 복잡하게 할 수 있는데, 이는 결국 형광 분자를 자극하는 데 … dnd beyond 50% off players handbookWebPhotobleaching of Venus or YFP (> 50%) did not alter the shape of the emission spectra acquired with an LSM510 confocal microscope using two-photon excitation between 750 and 940 nm (Fig. 1b, and ... create as select teradataWebSep 1, 2014 · Spectral data were processed with Renishaw Wire 3.2 software.
