Rare earth-doped nanoparticles applications in biological imaging and tumor treatment

Reporter: Irina Robu, PhD

Bioimaging  aims to interfere as little as possible with life processes and can be used to gain information on the 3-D structure of the observed specimen from the outside. Bioimaging ranges from  the observation of subcellular structures and the entire cells over tissues up to entire multicellular organisms. The technology uses light, fluorescence, ultrasound, X-ray, magnetic resonance as sources of imaging. The more common imaging is fluorescence imaging which is used to monitor the dynamic interaction between the drug molecules and tumor cells and the ability to monitor the real time dynamic process in biological tissues.

Researchers from the Xi’an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences (CAS) described the recent progress they made in the rare earth-doped nanoparticles in the field of bio-engineering and tumor treatment. It is well known that producing small nanoparticles with good dispersion and exploitable optical coherence properties is highly challenging. According to them, these rare earth-doped nanoparticles can be vested with additional capabilities such as water solubility, biocompatibility, drug-loading ability and the target ability for different tumors by surface functionalization. The luminescent properties and structure design were also looked at.

According to the Chinese researchers, for applying the RE-doped NPs to the diagnosis and treatment of tumors, their first goal is to improve water solubility and biocompatibility.  The second goal would be to give the nanoparticles the ability to target tumors by surface functionalization. Lastly, biocompatible water-soluble tumor-targeting NPs can be used as carriers to load drugs for treatment of tumor cells. All things considered, the recent research progress on the development of fluorescence intensity of NPs, surface modification, and tumor targeted diagnosis and treatment has also been emphasized.
