Abstract
Embodiments herein provide a nanoparticle, such as a metal nanoparticle, coupled to a linker molecule to form a nanoparticle-linker construct. In an embodiment, a nanoparticle-linker construct may be further bound to a substrate to take advantage of one or more properties of the nanoparticle. In an embodiment, a functionalized nanoparticle (a nanoparticle having a reactive functionality) may be bound to a linker to form a functionalized nanoparticle-linker construct which may in-turn be bound to a substrate.
Claims28
A method for attaching a functionalized nanoparticle to a substrate, comprising:
- combining a functionalized nanoparticle, a linker molecule, and a substrate to form a mixture;
- and
- stimulating the mixture for a time sufficient for the functionalized nanoparticle to attach via the linker molecule to the substrate.
A functionalized substrate comprising:
- a functionalized nanoparticle;
- a substrate;
- and
- a linker molecule having a first functionality bound to the functionalized nanoparticle and a second functionality bound to the substrate.
A functionalized nanoparticle construct, comprising:
- a functionalized nanoparticle;
- and
- a multi-functional linker molecule having at least a first end and a second end, the first end having a nanoparticle binding moiety bound to the functionalized nanoparticle, and the second end having a functional binding moiety with an affinity for at least one substrate, wherein the linker molecule has a formula of X-R-Y, in which X represents the functionalized nanoparticle binding moiety, Y represents the functional binding moiety, and R is at least one of alkyl, aryl, vinyl, oligomer, and polymer.
