Tracerpartikel
A tracer particle, or tracerpartikel, is a small particle introduced into a system to follow its movement, transport, or reaction pathways. The goal is to observe how a fluid moves, how substances diffuse, or how chemical or biological processes proceed, with minimal disruption to the system.
Tracer particles are labeled with detectable signals. They can be radioactive isotopes, fluorescent dyes or nanoparticles,
Applications span medicine, environmental science and industrial research. In medicine, tracers help track drug delivery or
Detection relies on the tracer's label. Radiotracers are detected by radiometric instruments; fluorescent tracers are observed
Safety and limitations include potential perturbation of the system, toxicity concerns, and regulatory considerations. The tracer
