Initially, magnetic solids were used to separate biological species. Reported the recovery of radium, lead and polonium from seawater samples using a magnetic adsorbent consisting of manganese dioxide coated magnetite. Introduced a new magnetic separation method called magnetic solid-phase extraction (mspe), whereby target analytes. 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993. Chou, plasmonic bar-coupled dots-on-pillar cavity antenna with dual resonances for infrared absorption and sensing performance and nanoimprint fabrication, acs nano. A novel immunoassay has been developed for the quantitative determination of polybrominated biphenyls (pbbs) using indirect competitive format. A new method was developed to synthesize pbbs congener (pcb15) hapten and its artificial immunogen, then the polyclonal antibodies. The assay was optimized concerning the coating conjugate and antibody concentration, incubation time and temperature. Nanoparticles of laf3 doped with ln3 (ln eu, er, nd, and ho) have been prepared that are dispersible in organic solvents. From the spectrum of eu3 it has been concluded that the dopant ion occupies a la3 site. A given possible explanation for this is a different probability of nonradiative decay for ions at or near the surface and ions. A single-step synthesis for monodisperse and hexagonal-phase () nayf 4yb, er upconversion nanophosphors (ucnps) with a consistent hexagonal prism shape in the size range from 18 to 200 nm was achieved. The kinetic mechanisms for the particle phase transition and growth were examined. The numerous oxygen-containing functional groups on the surface of graphene oxide (go) provide more possibilities for the design of graphene composites. Finally, the future development of graphene-based adsorbents for the removal of antibiotics in aqueous solutions is discussed.
