A peptide targeted contrast agent, CLT1-(Gd-DTPA), was synthesized for molecular imaging of fibronectin-fibrin complexes in tumor tissue with magnetic resonance imaging (MRI). The T(1) and T(2) relaxivities of CLT1-(Gd-DTPA) were 4.22 and 4.45 mM(-1) s(-1) at 3 T, respectively. The targeted contrast agent specifically bound to tumor tissue and resulted in significant tumor contrast enhancement ...
Photoacoustic imaging of living subjects offers higher spatial resolution and allows deeper tissues to be imaged compared with most optical imaging techniques. As many diseases do not exhibit a natural photoacoustic contrast, especially in their early stages, it is necessary to administer a photoacoustic contrast agent. A number of contrast agents for photoacoustic imaging have been suggested p...
Terbium(III) was coordinated to four novel 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) amphiphilic bisamide ligands. The complexes were assembled into mono-disperse micellar nano-aggregates and for the first time Tb(III) has been evaluated as a single lanthanide negative bimodal contrast agent for MRI/OI. The complexes show characteristic Tb(III) emission with quantum yields...
Nanoparticles have become more and more prevalent in reports of novel contrast agents, especially for molecular imaging, the detection of cellular processes. The advantages of nanoparticles include their potency to generate contrast, the ease of integrating multiple properties, lengthy circulation times, and the possibility to include high payloads. As the chemistry of nanoparticles has improve...

Glycidyl nitrate is a valuable chemical used for manufacturing poly (glycidyl nitrate) as an energetic polymer. In this study glycidyl nitrate was synthesized by ring opening reaction of epichlorohydrin by nitric acid as nitrating agent in the presence of several different catalysts, and the effect of different catalysts on one pot synthesis of glycidyl nitrate was evaluated. The main purpose o...
