autofluorescent
Definition
- Adjective:
- Emitting light via self-induced fluorescence: Describes a substance or material that naturally fluoresces when exposed to light of a specific wavelength, without requiring the addition of external dyes or labels. This property is intrinsic to the material's molecular structure.
Usage Examples
- Adjective:
- The chlorophyll in plant leaves is autofluorescent under ultraviolet light.
- Researchers studied the autofluorescent properties of certain proteins to track them within living cells.
- The mineral exhibited a bright, autofluorescent glow in the darkroom.
Advanced Usage
- Scientific Context: The term is primarily used in scientific fields like biology, microscopy, and materials science to describe inherent fluorescence.
- Autofluorescent signals can sometimes interfere with experiments that use added fluorescent dyes.
- Technical Description: Often used to contrast with stained or labeled samples.
- The background noise was high due to autofluorescent components in the tissue sample.
Variants and Related Words
- Autofluorescence (n): The phenomenon or property of being autofluorescent.
- The autofluorescence of the lens in the human eye can be measured.
- Fluorescent (adj): Emitting light after absorbing radiation. (Note: This is a broader term; 'autofluorescent' specifies that the fluorescence is intrinsic, not applied).
Synonyms
- Self-fluorescent: Emitting light through its own fluorescence. (Less common technical synonym).
- Intrinsically fluorescent: Having a natural capacity for fluorescence.
Antonyms
- Non-fluorescent: Not emitting light under such conditions.
- Stained/Labeled: Referring to fluorescence that comes from an externally applied dye or tag.
Adjective
- emitting light via self-induced fluorescence
