FEATURE ARTICLE
versions of these materials using superparamagnetic nanoparticle
cores coated with a silica spacer followed by a gold shell. The
optical properties can be tuned by adjusting the overall particle
size or the diameter of the gold shell. The gold surface provides
a useful substrate for functionalization with biological molecules
or other custom surface functionality. The reaction conditions
have been tuned to modify sizes between 100-300 nm.
It has also fabricated magnetic-fluorescent composite particles,
consisting of a magnetic core, silica spacer and fluorescent
quantum dots covalently bound to the silica surface. The quantum
dots are functionalized to allow further coupling of biomolecules
or other molecules.
A wide variety of magnetic nanomaterials can be produced via
the thermal decomposition of organometallic precursors at high
temperature in organic solvents, producing highly monodisperse,
organic-solvent compatible nanoparticles. Iron oxide nanoparticles
coated with oleic acid can range from 4 to 20 nm in diameter
by modifying reaction conditions, and easily dispersed into a
wide variety of organic solvents. The particles can be transferred
into aqueous-compatible solvents by modifying the surface or
by growing a uniform silica coating around the particles. They
can be further customized with surface functionality tailored for
specific applications.
Overall, a wide variety
of magnetic metal ferrite
and alloy nanoparticles
can be produced with
customizable sizes,
shapes and compositions.
The size and ironto-platinum
ratio can
be adjusted to alter the
magnetic and catalytic
properties. Monodisperse
iron platinum
(FePt) nanoparticles
have been fabricated
with diameters of approximately
3 nm.

Monodisperse iron platinum
nanoparticles
Iron okide nanoparticles
Iron oxide nanoparticles with a diameter of ~60 nm have been
fabricated, coated with uniform silica shells and quantum dots
covalently bound for a final particle of ~100 nm. The reaction
conditions can be tuned to modify the size of the core and shell
thickness, and quantum dots with different emission properties
can be substituted to produce samples with tailored fluorescence.
