Figure 13.

A schematic representation for the design of ¹⁸F-radiolabelled MSNs. Cyclooctyne functionalised MSNs (DBCO-MSNs) were first incubated with RAW cells, with the incubated samples then injected into nude mice bearing a tumour or atherosclerosis plaques. One to eight days later, ¹⁸F-labelled azide was injected into the mice to visualise the tumour/atherosclerotic sites in vivo. Reprinted with permission from reference [152]. Copyright (2019) Elsevier.
