: autofluorescencia
  • The presence of autofluorescence in the tissue samples indicated the need for further investigation of the underlying biology.

Examples

  • There are a number of potential artifact sources in widefield calcium imaging, including movement, bleaching, and autofluorescence.

  • The researchers noted that the autofluorescence of the samples made it difficult to interpret the results.

  • The F0 value was additionally corrected for background autofluorescence measured in a nearby non-transfected region.

Morphology

autofluorescence = fluorescence (transparent) = auto + fluorescence

The meaning is directly compositional: 'auto-' expresses 'self' or 'by itself', and 'fluorescence' names the emission of light.

Etymology

Autofluorescence breaks into auto- meaning 'self', like in automatic, and fluorescence meaning 'a glow or light given off when light hits something', like a fluorescent lamp. So autofluorescence is the 'self-glow' of cells or tissues that give off light by themselves when you shine light on them, without adding any dyes.
