Abstract
The invention provides multisegmented, multifunctional magnetic nanowires for the probing and manipulation of molecules at the cellular and subcellular level. The different segments of the nanowire may have differing properties, including a variety of magnetic, non-magnetic, and luminescent behavior. Differences in surface chemistry allow different segments of a single nanowire to be functionalized with different multiple functional groups and/or ligands, giving the wire chemical multifunctionality.
Claims17
A magnetic nanowire comprising:
- a plurality of segments, wherein said segments are formed from metal or metal alloys, and wherein at least one of said plurality of segments is magnetic;
- and
- functional groups associated with at least one of said segments or ligands associated with at least one of said segments.
A method of fonning a functionalized magnetic nanowire, comprising:
- providing a magnetic nanowire having a plurality of segments, wherein said segments are formed from metal or metal alloys, and wherein at least one of said plurality of segments is magnetic,
- associating functional groups or ligands with at least of one said segments, wherein said step of associating forms a functionalized magnetic nanowire.
A magnetized cell, comprising,
- a cell, and
- an associated magnetic nanowire, wherein said magnetic nanowire comprises a plurality of segments, wherein said segments are formed from metal or metal alloys, and wherein at least one of said plurality of segments is magnetic;
- and
- functional groups associated with at least one of said segments or ligands associated with at least one of said segments.
A magnetic nanowire consisting of:
- one or more segments, wherein said segments are formed from metal or metal alloys, and wherein at least one of said one or more segments is magnetic;
- and
- functional groups associated with at least one of said segments or ligands associated with at least one of said segments.
A magnetic nanowire comprising:
- a plurality of segments, wherein said segments are formed from metal or metal alloys, and wherein at least one of said plurality of segments is magnetic, and wherein a diameter of said magnetic nanowire is from 10 to 300 nanometers;
- and
- functional groups associated with at least one of said segments or ligands associated with at least one of said segments.
