Abstract
The invention generally relates to systems and methods for producing metal clusters; functionalized surfaces; and droplets including solvated metal ions. In certain aspects, the invention provides methods that involve providing a metal and a solvent. The methods additionally involve applying voltage to the solvated metal to thereby produce solvent droplets including ions of the metal containing compound, and directing the solvent droplets including the metal ions to a target. In certain embodiments, once at the target, the metal ions can react directly or catalyze reactions.
Claims20
A functionalized substrate comprising:
- a substrate;
- and
- a plurality of discrete spots that are patterned on the substrate, each of the plurality of discrete spots comprising an aggregate of uncapped metal nanoparticles, wherein each nanoparticle of the aggregate maintains its individual features.
A method for producing a functionalized substrate, the method comprising:
- providing a substrate;
- and
- spraying, under ambient conditions, metal ions from a droplet emitter onto a discrete location on the substrate, thereby producing an aggregate of metal nanoparticles at the discrete location on the substrate.
A functionalized substrate comprising:
- a substrate;
- and
- at least one discrete spot on the substrate, the spot comprising a sample and an aggregate of uncapped metal nanoparticles, wherein each nanoparticle of the aggregate maintains its individual features.
