CXCR4-Targeted and MMP-Responsive Iron Oxide Nanoparticles for Enhanced Magnetic Resonance Imaging**

MRI offers high spatial resolution with excellent tissue penetration but it has limited sensitivity and the commonly administered contrast agents lack specificity. In this study, two sets of iron oxide nanoparticles (IONPs) were synthesized that were designed to selectively undergo copper-free click conjugation upon sensing of matrix metalloproteinase (MMP) enzymes, thereby leading to a self-as...

Scavenger receptor-AI-targeted iron oxide nanoparticles for in vivo MRI detection of atherosclerotic lesions.

OBJECTIVE In search of molecular imaging modalities for specific detection of inflammatory atherosclerotic plaques, we explored the potential of targeting scavenger receptor-AI (SR-AI), which is highly expressed by lesional macrophages and linked to effective internalization machinery. APPROACH AND RESULTS Ultrasmall superparamagnetic iron oxide particles were conjugated to a peptidic SR-AI l...

Targeted Paclitaxel by conjugation to iron oxide and gold nanoparticles.

The Fe(3)O(4) nanoparticles, tailored with maleimidyl 3-succinimidopropionate ligands, were conjugated with paclitaxel molecules that were attached with a poly(ethylene glycol) (PEG) spacer through a phosphodiester moiety at the (C-2')-OH position. The average number of paclitaxel molecules/nanoparticles was determined as 83. These nanoparticles liberated paclitaxel molecules upon exposure to p...

Targeted MRI for Breast Cancer using Iron Oxide Nanoparticles

Magnetic Resonance Imaging (MRI) utilizes a powerful magnetic field to align the nuclear magnetization of hydrogen atoms in water in the body without the use of ionizing radiation. Iron oxide (IO) nanoparticles are the only FDA approved nanoparticles used as a MRI contrast agent. Paramagnetic IO nanoparticles can induce remarkably strong magnetic resonance imaging contrast and have a large surf...
