Optimization of Fe3O4@Ag nanoshells in magnetic field-enriched surface-enhanced resonance Raman scattering for malaria diagnosis by Yuen, Clement, Liu, Quan

“…In this study, we present the optimization of nanoparticles used in the magnetic field enriched SERRS by tuning the core size and shell thickness of nanoparticles with an iron oxide core and a silver shell (Fe3O4@Ag). The discrete dipole approximation (DDA) model was introduced to investigate the localized electromagnetic field distributions and extinction efficiencies of the aggregate of Fe3O4@Ag and β-hematin, in correlation with their magnetic field enriched SERRS performance. …”

Magnetic field enriched surface enhanced resonance Raman spectroscopy for early malaria diagnosis by Yuen, Clement, Liu, Quan

“…We report magnetic field-enriched surface-enhanced resonance Raman spectroscopy (SERRS) of β —hematin crystals, which are the equivalent of hemozoin biocrystals in spectroscopic features, by using magnetic nanoparticles with iron oxide core and silver shell (Fe 3 O 4 @Ag ). The external magnetic field enriches β —hematin crystals and enhances the binding between β —hematin crystals and magnetic nanoparticles, which provides further improvement in SERRS signals. …”
