Synthesis and characterization of [(110m)Ag]-nanoparticles with application to whole-body autoradiography of aquatic organisms

Appl Radiat Isot. 2011 Oct;69(10):1415-21. doi: 10.1016/j.apradiso.2011.06.017. Epub 2011 Jul 6.

Abstract

Silver nanoparticles (AgNp) were synthesized using aqueous solution of silver nitrate ([(110m)Ag]NO₃) with poly(allylamine) as a reducing agent and a stabilizer of the AgNp suspension. Nanoparticles were characterized by absorption spectroscopy, particle size analysis, atomic force microscopy (AFM), and transmission (TEM) electron microscopy. Different size nanoparticles (10-30 nm and 70-90 nm) were obtained by varying the polymer concentration and reaction time. The application of [(110m)Ag]AgNP to environmental studies, using nuclear techniques such as in vivo gamma counting and whole-body autoradiography, is demonstrated and discussed.
