Biodegradable human serum albumin nanoparticles as contrast agents for the detection of hepatocellular carcinoma by magnetic resonance imaging Waralee Watcharin; Schmithals, Christian; Pleli, Thomas; Koberle, Verena; Korkusuz, Hudayi; Huebner, Frank; Zeuzem, Stefan; Korf, Hans W.; Vogl, Thomas J.; Rittmeyer, Claudia; Terfort, Andreas; Piiper, Albercht; Gelperina, Svetlana; Kreuter, Jorg (Elsevier, 2014)
Tumor visualization by magnetic resonance imaging (MRI) and nanoparticle-based contrast agents may improve the imaging of solid tumors such as hepatocellular carcinoma (HCC). In particular, human serum albumin (HSA) nanoparticles appear to be a suitable carrier due to their safety and feasibility of function- alization. In the present study HSA nanoparticles were conjugated with gadolinium diethylenetriamine- pentaacetic acid (Gd-DTPA) using carbodiimide chemistry. The nanoparticles had a uniform spherical shape and a diameter of 235 ± 19 nm. For ...
Detection of hepatocellular carcinoma in transgenic mice by Gd-DTPA- and rhodamine 123-conjugated human serum albumin nanoparticles in T1 magnetic resonance imaging Waralee Watcharin; Schmithals, Christian; Pleli, Thomas; Köberle, Verena; Korkusuz, Hüdayi; Hübner, Frank; Waidmann, Oliver; Zeuzem, Stefan; Korf, Horst-Werner; Terfort, Andreas; Gelperina, Svetlana; Vogl, Thomas J.; Kreuter, Jörg; Piiper, Albrecht (2015)
Nanoparticle (NP)-based contrast agents that enable high resolution anatomic T1-weighted magnetic resonance imaging (MRI) offer the prospect of improving differential diagnosis of liver tumors such as hepatocellular carci- noma (HCC). In the present study, we investigated the possibility of employing novel non-toxic human serum albumin nanoparticles conjugated with Gd-DTPA and rhodamine 123 (Gd-Rho-HSA-NPs) for the detection of HCC by T1-weighted MRI. In addition, the inﬂuence of surface coating of the NPs with poloxamine 908, which al- ters the ...
Surface Modification of Magnetic Iron Oxide Nanoparticles with Biodegradable Polymers for Plasma Protein Adsorption Waralee Watcharin (Assumption University, 2017-09)
Magnetic iron oxide nanoparticles have been proposed as one of the most popular and efficient drug carrying magnetic materials used in human treatment and diagnosis due to their non-toxicity, high stability and high magnetic responses. Magnetic iron oxide nanoparticles (MNP) were obtained by chemical co-precipitation of iron salts in the presence of ammonia. The prepared magnetic particles were modified with gallic acid to reduce aggregation of particles, maintain magnetic stability, and slowdown degrading ...
