Abstract
Multifunctional nanoparticles can include two or more different populations of nanocrystals that impart a combination of properties arising from the constituent populations in a single, multifunctional nanoparticle.
Claims35
A multifunctional nanoparticle comprising:
- a first population of nanoparticles and an assembly polymer associated with the first population of nanoparticles.
A method of making a multifunctional nanoparticle, comprising:
- forming a mixture including a first solvent, a second solvent which is substantially immiscible with the first solvent, a first population of nanoparticles, and a surfactant;
- removing at least a portion of the first solvent from the mixture;
- and
- adding an assembly polymer to the mixture, thereby associating the assembly polymer with the first population of nanoparticles to form a multifunctional nanoparticle including the first population of nanoparticles and the assembly polymer.
A method of studying a living organism comprising adding a multifunctional nanoparticle into the living organism, wherein the multifunctional nanoparticle includes a first population of nanoparticles and an assembly polymer associated with the first population of nanoparticles.
The method of claim 37, wherein the living organism is a cell.
The method of claim 37, wherein the living organism is a mouse.
The method of claim 37, further comprising applying a magnetic field to the multifunctional nanoparticle.
The method of claim 37, wherein the multifunctional nanoparticle is both magnetic and photoluminescent.
The method of claim 37, wherein the multifunctional nanoparticle includes magnetic constituent nanoparticles and photoluminescent constituent nanoparticles.
