But when encapsulated complexes were illuminated by continuous, near-infrared laser light, they worked substantially better than under bulk heating while leaving the solution at near-room temperature. The researchers found the complexes robust enough for weeks of reuse.
"As far-fetched as it sounds, I think chemical companies will be interested in the idea of using light to make chemicals," Wong said. "They're always interested in new technologies that can help make chemical products more cheaply."
He sees other possible uses for the new approach in the production of fuels from degradation of biomass like lignocellulose; for drug manufacture on demand maybe from nanoparticle-infused tattoos on the body; or even for lowering blood sugar concentrations as a different way to manage diabetes.
"That we can now make these particles is great," Wong said. "The next exciting part is in thinking about how we can deploy them."
