Gd₂O₃ nanoparticles in hematopoietic cells for MRI contrast enhancement.

Anna Hedlund et al.

International journal of nanomedicine, 6, 3233-3240 (2012-01-10)

As the utility of magnetic resonance imaging (MRI) broadens, the importance of having specific and efficient contrast agents increases and in recent time there has been a huge development in the fields of molecular imaging and intracellular markers. Previous studies

Designing tripodal and triangular gadolinium oxide nanoplates and self-assembled nanofibrils as potential multimodal bioimaging probes.

Taejong Paik et al.

ACS nano, 7(3), 2850-2859 (2013-02-26)

Here, we report the shape-controlled synthesis of tripodal and triangular gadolinium oxide (Gd2O3) nanoplates. In the presence of lithium ions, the shape of the nanocrystals is readily controlled by tailoring reaction parameters such as temperature and time. We observe that

Cytotoxic and genotoxic characterization of titanium dioxide, gadolinium oxide, and poly(lactic-co-glycolic acid) nanoparticles in human fibroblasts.

Magdiel Inggrid Setyawati et al.

Journal of biomedical materials research. Part A, 101(3), 633-640 (2012-08-29)

Engineered nanomaterials have become prevalent in our everyday life. While the popularity of using nanomaterials in consumer products continues to rise, increasing awareness of nanotoxicology has also fuelled efforts to accelerate our understanding of the ill effects that different nanomaterials

In vitro and in vivo investigations of upconversion and NIR emitting Gd₂O₃:Er³⁺,Yb³⁺ nanostructures for biomedical applications.

Eva Hemmer et al.

Journal of materials science. Materials in medicine, 23(10), 2399-2412 (2012-05-17)

The use of an "over 1000-nm near-infrared (NIR) in vivo fluorescence bioimaging" system based on lanthanide containing inorganic nanostructures emitting in the visible and NIR range under 980-nm excitation is proposed. It may overcome problems of currently used biomarkers including

Ultra-small gadolinium oxide nanoparticles to image brain cancer cells in vivo with MRI.

Luc Faucher et al.

Contrast media & molecular imaging, 6(4), 209-218 (2011-08-24)

The majority of contrast agents used in magnetic resonance imaging (MRI) is based on the rare-earth element gadolinium. Gadolinium-based nanoparticles could find promising applications in pre-clinical diagnostic procedures of certain types of cancer, such as glioblastoma multiforme. This is one
