What are the applications of FRET-based immunosensors?

In medicine, FRET-based immunosensors are used for diagnosing various diseases, including infectious diseases and cancer. For example, it is used to detect pathogens such as bacteria or viruses in clinical samples. FRET-based immunosensors are also used for detecting environmental contaminants, toxins, or pollutants. For example, they are used to assess heavy metals or pesticides in water or soil samples. FRET-based immunosensors are also used for studying protein-protein interactions, such as those involved in cellular signaling pathways or disease pathways.
