Metallic nanoparticles drug delivery

Transition metal nanoparticles have attracted great attention due to their unique size-dependent properties and applications in diverse areas, including magnetic storage materials, catalysis, sensors and drug delivery. Depositions of various Pt-containing alloys are summarized in Table 2. Particularly, chemically synthesized transition metal alloy... 

These clays have been hybridized with diverse structural types of components such as nanoparticles, clusters, complex compounds, polymers, molecules, and ions. Their potential apphcations are found in many fields as inorganic catalysts, adsorbents, ceramics, coatings, and even drug delivery carriers. Various preparation methods have been developed such as pillaring, intercalation, and delamination techniques. The representative examples include organic-clay hybrids," metal oxide-pillared clays, " and bioclay hybrids. ... 

Silver reduction from its complex precursors is of interest to produce silver nanoparticles [1,2]. Metal colloids can be stabilized by functional groups in polyelectrolytes and surfactants [1], The stabilization is a useful method for the directional drug delivery and the prolongation effect. 

Recent advances using nanoparticles of iron oxide and other transition metals have been touted as a means for targeted drug delivery within the body. This is because, as a nanoparticle, they have the capacity to have all the dipoles of the atoms line up and act in unison, making them extremely sensitive to magnets. This happens when the atom becomes magnetized which makes it polarized. 

Multicomponent composites built by LbL assembly may consist not only of nanocrystals but also of nanowires, biomolecules, dyes, and functional polymers. In addition, metal nanoparticles may be employed with potential applications in the fields of drug delivery and biodetection, energy harvesting, optical signal processing, and emission enhancement or quenching [70, 93].
