Digistain Nasıl Çalışır?

Bir biyomolekülün farklı kimyasal grupları, kızılötesi ışığı çok spesifik dalga boylarında absorbe eder. As the light passes through or reflects off the sample, certain wavelengths are absorbed, while others pass through. This absorption creates a unique pattern, known as an infrared spectrum, which is a graph showing the amount of light absorbed at each wavelength.

The peaks on the spectrum represent wavelengths where absorption occurs, corresponding to specific vibrations of chemical bonds within the molecule. By analysing these peaks, scientists can identify the functional groups present in a biomolecule. This allows them to determine its molecular structure and composition by acting as a molecular “fingerprint”, enabling precise identification of the biomolecule based on its unique vibrational characteristics.

By analysing wavelengths that are known to be absorbed by nucleic acids and cell proteins. This imaging approach enables Digistain to measure chemical concentrations associated with tumour malignancy, precisely determine the characteristics of cancer cells and quantify validated pathology markers correlated to tumour proliferation.
