“…Haase and co-workers performed the in vivo analysis of sizeand time-dependent uptake of NaYF 4 :Yb,Er@NaGF 4 UCNPs by pumpkin seedlings. 435 It was found that the UCNP accumulation took place eventually in the leaf margin ( Figure 39b,c). The uptake of smaller UCNPs was faster than that of larger UCNPs, leading to higher concentrations of smaller UCNPs at early times of incubation.…”

“…Up to now, some works pertaining to the short‐term/subchronic/long‐term toxicities, biodistribution, and excretion behavior of UCNPs in live organisms such as nude mouse and Caenorhabditis elegans have been reported . However, reports on the toxicities and the interactions of UCNPs with plants are scarce . As an important component of the environment, plants play a significant role in preserving the ecological system equilibrium and can provide one of the main food sources of animals and human beings .…”

The increasing uses of rare-earth-doped upconversion nanoparticles (UCNPs) have obviously caused many concerns about their potential toxicology on live organisms. In addition, the UCNPs can be released into the environment, then transported into edible crop plants, and finally entered into food chain. Here, the soybean is chosen as a model plant to study the subchronic phytotoxicity, translocation, and biotransformation of NaYF4 UCNPs. The incubation with UCNPs at a relative low concentration of 10 μg mL(-1) leads to growth promotion for the roots and stems, while concentration exceeding 50 μg mL(-1) brings concentration-dependent inhibition. Upconversion luminescence imaging and scanning electron microscope characterization show that the UCNPs can be absorbed by roots and parts of the adsorbed UCNPs are then transported through vessels to stems and leaves. The near-edge X-ray absorption fine structure spectra reveal that the adsorbed NaYF4 nanoparticles are relatively stable during a 10 d incubation. Energy-dispersive X-ray spectrum further indicates that a small amount of NaYF4 is dissolved/digested and can transform into Y-phosphate clusters in roots.

“…The appropriate functionalization of the NP surface and the introduction of targeting molecules such as folic acid, some peptides, specific antibodies and growth factors permits in some cases a cellular targeting imaging [263][264][265]. In vivo luminescent bioimaging of bacteria [266,267], small animals (mostly mice) [268,269] and plants [262,270] with UCNPs has also been widely reported in the literature. Different processes of biomedical interest can be also studied in vivo by using UCNPs, as it is the case of the biodistribution of the NPs [271] and targeting [272][273][274][275].…”

Rare earth based nanostructured materials: synthesis, functionalization, properties and bioimaging and biosensing applications

Abstract:Rare earth based nanostructures constitute a type of functional materials widely used and studied in the recent literature. The purpose of this review is to provide a general and comprehensive overview of the current state of the art, with special focus on the commonly employed synthesis methods and functionalization strategies of rare earth based nanoparticles and on their different bioimaging and biosensing applications. The luminescent (including downconversion, upconversion and permanent luminescence) and magnetic properties of rare earth based nanoparticles, as well as their ability to absorb X-rays, will also be explained and connected with their luminescent, magnetic resonance and X-ray computed tomography bioimaging applications, respectively. This review is not only restricted to nanoparticles, and recent advances reported for in other nanostructures containing rare earths, such as metal organic frameworks and lanthanide complexes conjugated with biological structures, will also be commented on.
