1. chromophore is an isolated covalently bonded group which characteristically absorbs in the visible range of electromagnetic radiation. But fluorophore is any group capable of absorbing energy and emitting radiation with a longer wavelength.
2. Chromophores may have a overlapping ground singlet and excited singlet state but a fluorophore must have non overlapping S0 and S1 orbitals.
3. Chromophores can't emit energy but fluorophores can.
4. Chromophores are of 2 main types, extended π bond system and metal complex chromophore. Fluorophores are of 2 types, extrinsic and intrinsic.
5. Chromophores can't be quenched but fluorophores can.
6. Chromophores' absorption is not temperature dependent but fluorophores' fluorescing capacity is temperature dependent.
A chromophore is a part of a molecule that gives it its color, typically by absorbing specific wavelengths of light. A fluorophore, on the other hand, is a molecule that emits light upon excitation, commonly used in fluorescence microscopy and imaging techniques.

What chemicals are in glow sticks?
The glow stick contains two chemicals and a suitable dye (sensitizer, or fluorophore). The chemicals inside the plastic tube are a mixture of the dye and diphenyl oxalate. The chemical in the glass vial is hydrogen peroxide. --- Taken from Google search
Which ion carries the chromophore in an acidic dye?
The sulfonate ion carries the chromophore in an acidic dye. When it attaches to a colored molecule and gives it a negative charge, it results in an acid dye.
What are the terms used to describe the effect on chromophore by auxochrome?
The effect of auxochrome on a chromophore is described by terms like bathochromic shift (red-shift), hypsochromic shift (blue-shift), and hyperchromic effect (increase in absorbance intensity). These terms refer to the changes in the absorption spectrum of a molecule due to the presence of an auxochrome group.
What is an auxochrome?
An auxochrome is a functional group in a molecule that contains a lone pair of electrons which can interact with a chromophore group to modify its color. Auxochromes are responsible for shifting the absorption spectra of molecules towards longer wavelengths, leading to a change in color.
How much difference between 2oz and 1.69 oz?
The difference between 2 oz and 1.69 oz is 0.31 oz.
What is difference between chromophore and auxochrome?
Chromophores are responsible for giving dyes their color by absorbing certain wavelengths of visible light and transmitting or reflecting others.Auxochromes modify the ability of a chromophore to absorb light. They often result in the deepening and intensifying of the color of compounds
What is used to make quantum dots fluoresce for in vivo imaging?
fluorophore
What effect does a chromophore have on benzene?
A chromophore is a group of atoms within a molecule that gives rise to color when exposed to light. When a chromophore group is attached to benzene, it can alter the absorption or emission of light by the benzene molecule, causing it to appear colored or influencing its interactions with light.

Why CMH2DCFDA is light sensitive?
CMH2DCFDA is light sensitive because the probe contains a fluorophore that can be activated by light, leading to non-specific oxidation reactions and background fluorescence. Exposure to light can result in premature activation of the fluorophore, affecting the accuracy of the assay results. It is recommended to store CMH2DCFDA in a dark environment to maintain its stability and reliability.
What is an autofluorescence?
An autofluorescence is an instance of self-induced fluorsencence, or the ability to become fluorescent via substances other than the organism's main fluorophore.
What is difference between as on and as at?

Is methylene blue a chromophore?
Yes, methylene blue is a synthetic dye that acts as a chromophore. It appears as a blue solid in its oxidized form and is commonly used in biology and medicine for staining purposes.
What are the differences between California and Florida?

Are compounds that consist only of a cromophore considered to be stains?
No, compounds consisting only of a chromophore are not considered stains. Stains typically consist of both a chromophore (which provides color) and an auxochrome (which helps the dye bind to the material being colored). The auxochrome is necessary for the stain to effectively bind to the material and impart color.
