Reactive aluminum metal nanoparticles within a photodegradable poly(methyl methacrylate) matrix

- Core-matrix aluminum nanoparticles synthesized and passivated with poly(methyl methacrylate) (PMMA).
- Reactive metal nanomaterial stable in air for several weeks.
- UV photolysis of photodegradable PMMA cap affords kinetically activated and more reactive aluminum nanoparticles.
- New generation of core-matrix reactive metal nanoparticles with an environmentally responsive cap.
