Ambient Plasma Synthesis of Si‐Fe Hollow Nanoparticles and Their Biocompatibility and Lithium Storage Capacity

Si-Fe hollow nanoparticles are synthesized facilely using an ambient hetero­geneous plasma for the first time for both biomedical and energy storage applications. This provides new perspectives and useful information for the design of efficient, low-cost, environmentally-friendly nanomaterials for biomedical (drug/gene carriers) and energy storage (anode materials in lithium ion batteries) applications.
