This study explored the imaging capability of our frequency-domain photoacoustic (FD-PA) system that utilizes correlation processing alias “photoacoustic radar” and ultrasonic phased array for imaging of soft tissues. The probe imaging capabilities were studied using tissuemimicking phantoms, tissue samples ex vivo, blood vessels in a human wrist and a rat tumour model in vivo. Our experimental...
Introduction Bone marrow-derived mesenchymal stem cells (BMSCs) possess tremendous therapeutic potential because of their capacity to differentiate into multiple functional lineages. To assess the efficacy of BMSCs cell therapy, MRI methods are being developed to monitor their bio-distribution in longitudinal studies. Although, labeling BMSCs with iron-oxide nanoparticles can facilitate their i...
Macroporous chitosan spheres encapsulating superparamagnetic iron oxide nanoparticles were synthesized by a facile and effective one-step fabrication process. Ferro-gels containing ferrous cations, ferric cations and chitosan were dropped into a sodium hydroxide solution through a syringe pump. In addition, a sodium hydroxide solution was employed for both gelation (chitosan) and co-precipitati...
Using magnetic nanoparticles to absorb alternating magnetic field energy as a method of generating localized hyperthermia has been shown to be a potential cancer treatment. This report demonstrates a system that uses tumor homing cells to actively carry iron/iron oxide nanoparticles into tumor tissue for alternating magnetic field treatment. Paramagnetic iron/ iron oxide nanoparticles were synt...
in the present study, fe3o4 super paramagnetic nanoparticles were synthesized via co-precipitation of fe3+ and fe2+ chloride salts in the presence of ammonia solution. the product was characterized by fourier transform infrared spectroscopy (ft-ir), transmission electron microscopy (tem), and zeta–potential particle size distributing methods. the synthetic procedure of nano iron oxides were opt...
A new kind of magnetic induction heating materials-carbon coated iron nanoparticles(CCINS) was prepared by arc method and they were used for cancer therapy. The measurement of nanomaterials revealed that they are super-paramagnetic and exhibit a very strong induction heating ability.The magnetic induction heating property was measured by the conduction by Bio-heat method. Heating effect of pig ...
