English: (A) Enzyme-based bioluminescence imaging. D-Luciferin is a substrate molecular probe that is acted upon by the enzyme Firefly Luciferase to result in bioluminescence via a chemiluminescent reaction under physiological conditions only within living cells expressing the firefly luciferase (fluc) gene. (B) Enzyme-based PET imaging. 18F-Fluoropenciclovir (18F-FPCV) or other acycloguanosines are substrate molecular probes phosphorylated by the herpes simplex virus type 1 thymidine kinase (HSV1-TK) enzyme to result in intracellular trapping of the probe in cells expressing the HSV1-tk gene. C) Receptor-based PET imaging. 18F-FESP is a ligand molecular probe interacting with the dopamine-2-receptor (D2R) to result in trapping of the probe on/in cells expressing the D2R gene.
