Cancer Nanotherapeutics Administered by Non-conventional Routes

Objective: The aim of this study was to formulate fluorescent-labeled targeted immunoliposome to visualize the delivery and distribution of drugs in real-time. Methods: In this study, fluorescent-labeled liposomes were decorated with anti-HER2 VHH or Herceptin to improve the monitoring of intracellular drug delivery and tumor cell tracking with minimal side effects. The conjugation efficiency of antibodies was analyzed by SDS-PAGE silver staining. In addition, the physicochemical characterization of liposomes was performed using DLS and TEM. Finally, confocal microscopy visualized nanoparticles in the target cells. Results: Quantitative and qualitative methods characterized the intracellular uptake of 110±10 nm particles with near 70% conjugation efficiency. In addition, live-cell trafficking during hours of incubation was monitored by wide-field microscopy imaging. The results show that the fluorescent-labeled nanoparticles can specifically bind to HER2-positive breast cancer with minimal off-target delivery. Conclusion: This kind of nanoparticles can have several applications in personalized medicine, especially drug delivery and real-time visualization of cancer therapy. Moreover, this method also can be applied in the targeted delivery of contrast agents in imaging and thermotherapy.
