Development of novel imaging probes for cancer diagnosis is critical for early disease detection and management. The past two decades have witnessed a surge in the development and evolution of radiolabeled nanoparticles as a new frontier in personalized cancer nanomedicine. The dynamic synergism of positron emission tomography (PET) and nanotechnology combines the sensitivity and quantitative nature of PET with the multifunctionality and tunability of nanomaterials, which can help overcome certain key challenges in the field...

In this study, we cover the convergence of radiochemistry for imaging and therapy with advances in nanoparticle (NP) design for biomedical applications. We first explore NP properties relevant for therapy and theranostics and emphasize the need for biocompatibility. We then explore radionuclide-imaging modalities such as positron emission tomography (PET), single-photon emission computed tomography (SPECT), and Cerenkov luminescence (CL) with examples utilizing radiolabeled NP for imaging. PET and SPECT have served as diagnostic workhorses in the clinic, while preclinical NP design examples of multimodal imaging with radiotracers show promise in imaging and therapy...

The emerging radionanomedicine has multifunctional and theranostic purposes. For these purposes, radionanomedicine should achieve the efficient and specific delivery of therapeutic agents by multifunctional characteristics, using low amounts of nanomaterials in vivo. Recent research on radiolabeled micelle-encapsulated nanomaterials has been made on the their efficacy and safety using a one-step surface modification method (Jeong's method). This one-step multifunctional approach to the nanoparticle can be the important challenge in producing effective nanoplatforms for cancer imaging and therapy...

UNLABELLED: Despite of promising preclinical results in the fields of in vivo theragnostics of nanomedicine, a majority of attempt for clinical translation has been blocked by unsolved concerns about possible hazards to human body. Theragnosis of nanomedicine relies on the property of huge surface area to volume ratio of nanomaterials, which can offer potential for multi-functionality. Radionanomedicine has a hybrid characteristic of tracer technology and multi-functionality. Thus, key advantage of radionanomedicine is a possibility of using low amount of nanomaterials for theragnosis...
