Magnetic nanoparticle detection

The availability of rapid and low-cost instruments to detect magnetic nanoparticles (MNPs) concentrations is vital in giant magnetoresistance (GMR)-based biosensors. This paper reports a new setup for a simple GMR sensor using the commercial chip AAL024 as a transducer.

A method for preconcentration of Al(III) prior to its determination by inductively coupled plasma-optical emission spectrometry (ICP-OES) was developed because the sensitivity of ICP-OES is insufficient for trace-level measurement of Al(III). The method is based on the use of Coriolus versicolor-immobilized γ-Fe2O3 magnetic nanoparticles as a solid phase sorbent. The best experimental conditions were found as pH 6.0, 2.0 mL/min flow rate, 100 mg amount of C. versicolor on 150 mg of γ-Fe2O3 nanoparticles, and 500 mL of sample volume. The Al(III) absorbed on biosorbent was eluted with 5.

In the present article, we report the biosensor can detect superparamagnetic nanoparticles (less than 10 nm in size) at various and low particle concentrations, which is of the importance role in biosensing applications. The nanoparticle ferrite (Fe3O4), Cobalt ferrite (CoFe2O4), Nickel ferrite (NiFe2O4) nanoparticles were synthesized by the high temperature thermal decomposition precursor method.

The first population-based cancer registry was set up in Hamburg (Germany) in 1926. Three nurses visited hospitals and medical practitioners in the city at regular intervals. They recorded the names of new cancer patients and transferred data to a central index in the health department. This index was compared once a week with official death certificates. Other popu- lation-based cancer registries were set up in subsequent decades, so that by 1955, almost twenty had been established in various countries....
