#cellular imaging
- Autoradiography — A biophysical method of investigation and structural imaging consisting of detecting and recording the spatial distribution of radioactive substances or isotope-labeled molecules (tracers), by directly exposing the biological or metallurgical sample onto a photographic emulsion or a digital sensor. This experimental process utilizes the self-emission of radiation (alpha, beta, or gamma) from the sample to expose the contact medium, serving as a fundamental technique in nucleic acid mapping, cellular metabolism studies, and protein localization.
