Silica nanoparticles coencapsulating gadolinium oxide and horseradish peroxidase for imaging and therapeutic applications.

Nikesh Gupta et al.

International journal of nanomedicine, 7, 5491-5500 (2012-12-13)

Mesoporous silica nanoparticles coencapsulating gadolinium oxide and horseradish peroxidase (HRP) have been synthesized in the aqueous core of sodium bis-(2-ethylhexyl) sulfosuccinate (AOT)-hexane-water reverse micelle. The average diameter of these silica particles is around 25 nm and the particles are spherical

Surface modification of gadolinium oxide thin films and nanoparticles using poly(ethylene glycol)-phosphate.

Andrée-Anne Guay-Bégin et al.

Langmuir : the ACS journal of surfaces and colloids, 28(1), 774-782 (2011-10-06)

The performance of nanomaterials for biomedical applications is highly dependent on the nature and the quality of surface coatings. In particular, the development of functionalized nanoparticles for magnetic resonance imaging (MRI) requires the grafting of hydrophilic, nonimmunogenic, and biocompatible polymers

A synergistically enhanced T(1) -T(2) dual-modal contrast agent.

Zijian Zhou et al.

Advanced materials (Deerfield Beach, Fla.), 24(46), 6223-6228 (2012-09-14)

Monodisperse Gd(2) O(3) -embedded iron oxide (GdIO) nanoparticles can simultaneously enhance the local magnetic field intensities of each other under an external magnetic field and result in synergistic enhancement of T(1) and T(2) effects. GdIO nanoparticles have the unique property

Cytotoxic aspects of gadolinium oxide nanostructures for up-conversion and NIR bioimaging.

Eva Hemmer et al.

Acta biomaterialia, 9(1), 4734-4743 (2012-09-12)

Bioimaging is an important diagnostic tool in the investigation and visualization of biological phenomena in cells and in medicine. In this context, up-converting Gd(2)O(3):Er(3+),Yb(3+) nanostructures (nanoparticles, nanorods) have been synthesized by precipitation methods and hydrothermal synthesis. Independent of size and

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
