ABSTRACT:
The presence of anomalies in biological tissues and cells in natural and cultured form (e.g. cancerous tissues or cells) is detected by infrared spectroscopy. A beam of infrared light is directed at a sample of tissues or cells in natural or cultured form containing the cells to be tested, and the anomaly is detected at at least one range of frequencies by determining whether changes in infrared absorption have occurred due to the vibration of at least one functional group of molecules present in the sample which is characteristic of the anomaly.
