• ]. Gadolinium-doped BNNTs were fabricated as an effective contrast agent in clinical applications of BNNTs [98]. Due to the high magnetic moment property of gadolinium, Gd-doped BNNTs can be applied as an MRI contrast agent. The high in vitro biocompatibility property of the Gd-doped BNNTs and the labeling of

• cell populations due to the Gd and B content, make these structures a novel negative contrast agent [98]. Conclusion It is clear that there is an increasing trend for the application of BNNTs in several fields from medicine to sensors. Although their synthesis is rather straightforward, it is still not

Thus, the clinically approved superparamagnetic iron oxide (SPIO) MRI contrast agent ResovistTM is taken up after

• , exploiting surface-enhanced (SE) fields limits the possibility to probe bulk materials. An alternative approach, which overcomes this limitation, consists in dispersing the nanostructures in the bulk of the medium to be probed, and use them as a contrast agent to enhance the optical signal in their

• ]. The first strong experimental evidence has been given by the investigation of DyDOTA (where H4DOTA = 1,4,7,10-tetraazacyclododecane N,N′,N′′,N′′′-tetraacetic acid) the Dy derivative of the famous GdDOTA that is a commercial contrast agent used in MRI [44]. In this molecule, lanthanide coordination is

• crosslinked with increasing amounts of glutaraldehyde and a dense particle structure was formed to incorporate the contrast agent. A decreasing standard deviation of the polydispersity indicated a narrow size distribution for particles that were crosslinked with higher amounts of glutaraldehyde (Figure 3

• ), even when there were high concentrations of the contrast agent present during desolvation procedure. Additionally, the influence of the adjusted pH value on particle properties during desolvation was observed. At a pH of 7.5 and 9.5 microparticles with a broad size distribution were generated (data not

• relaxation, and can be useful as a multimodal contrast agent for in vivo imaging [5]. It can also be easily doped with other lanthanides and exploited as a fluorescent tag, thus replacing other fluorescent organic molecules. Gadolinium oxide nanoparticles are also employed in site-specific drug delivery
