Farbstoffinjektion

Farbstoffinjektion, also known as dye injection, refers to the process of introducing a colored substance into a fluid or tissue for visualization or tracing purposes. This technique is employed across various scientific and medical fields.

In medicine, dye injections are commonly used in diagnostic imaging. For instance, contrast dyes are injected into blood vessels to highlight them during X-ray, CT, or MRI scans, helping to detect blockages or abnormalities. Ophthalmologists use fluorescein dye injections to visualize blood flow in the retina, aiding in the diagnosis of conditions like diabetic retinopathy. In surgical procedures, dyes can be injected to identify specific structures or pathways, such as lymphatic vessels or fistulas, ensuring precise intervention.

Beyond medicine, dye injection finds applications in environmental science and engineering. It is used to trace the movement of water in rivers, groundwater, or plumbing systems. This helps in understanding flow patterns, identifying sources of pollution, or detecting leaks. In research, dyes are used to label cells or molecules, allowing scientists to track their behavior and interactions under a microscope. The choice of dye depends on the specific application, considering factors like its color, stability, toxicity, and how it interacts with the target medium.
