Protein-directed synthesis of Bi2S3 nanoparticles as an efficient contrast agent for visualizing the gastrointestinal tract

Non-invasive imaging modalities such as computed tomography are often used for diagnosis and assessment of gastrointestinal (GI) disease status over the long-term. The physiology of the GI tract can be assessed with contrast agents. Here, we present common protein (bovine serum albumin, BSA) stabilized bismuth sulfide nanoparticles with robust X-ray attenuation. Under the optimal conditions, th...

Synthesized Gd2O3 nanoparticles as contrast agent

Introduction: Gd (III) ion has been known to be the best metal ion in the periodic table that can be used as a T1 MRI contrast agent. Gadolinium have 7 unpaired electrons and these electrons can make magnetic area. No other metal ions possess unpaired electron more than this. CAs based on the element Gd are classified as “positive”, by opposition to “negative” CAs. Nowadays, G...

Synthesis and evaluation of chitosan manganese-ferrite nanoparticles as MRI contrast agent

Magnetic nanoparticles are the good choice for using in MRI as the contrast agent. Iron oxide particles such as magnetite (Fe3O4) or its oxidized form maghemite (γ-Fe2O3) are the most commonly employed in biomedical applications. In this study, we synthesized and optimized the preparation of chitosan manganese-ferrite nanoparticles (CMn-Fe nps) and evaluated its ability for the mice macrophage ...
