Alternating magnetic field and NIR energy conversion on magneto-plasmonic FeO@APTES-Ag heterostructures with SERS detection capability and antimicrobial activity.

Multipurpose FeO@APTES-Ag heterostructures for mutual heat generation, SERS probing, and antimicrobial activity were fabricated using a three-step process. Silver metallic particles were precipitated on a thin silica shell that served as an interlayer with FeO nanocubes. The structural properties were studied by means of the powder X-ray diffraction technique, and selected area electron diffraction.
