Multi-Modal Nano-Theranostics Imaging

This application note highlights the process of designing ultra-small nanoparticles for multi-modal theranostics applications. Researchers at the University of Soochow have succeeded in designing a single entity theranostic agent with the right ratio of multi-modal diagnostic and therapeutic components in a very small, sub-3 nm nanodot composite. In addition to featuring improved biocompatibility and lower cytotoxicity, these ultra-small Bi2Se3 nanodots exhibit excellent performance for photoacoustic imaging and photothermal therapy and offer great potential for CT imaging and radiation therapy enhancement. Moreover, labeling with 99mTc and 188Re (as documented in a related publication) enables radioisotope diagnostics and therapy. MILabs ultra-high resolution multi-modal SPECT/CT system was used for in vivo biodistribution imaging and quantitation.

Ultra-Small Biocompatible Bi2Se3 Nanodots for Multimodal-Imaging-Guided Synergistic Radio-Photothermal Therapy against Cancer
Mao et al.,
ACS Nano 2016

SPECT imaging demonstrates quantitative in vivo biodistribution during 24h after injection of nanodots. 


MILabs’ high-resolution U-SPECT/CT system is used to:
  • Quantitate in vivo biodistribution and assess toxicity.
  • Reveal the dynamic behavior of the agent during 24h.
  • Analyze potential for using combined radioisotope and radiation therapy.
  • Study the efficiency of in vivo delivery to the lesion site(s).
