Green chemistry and nanofabrication in a levitated Leidenfrost drop [link]Paper  doi  abstract   bibtex   
Many challenges face researchers developing bottom-up alternatives to traditional top-down fabrication methods. Beneath the surface there has been a growing interest in minimizing the negative environmental repercussions of the rapidly advancing field. Here, as a novel concept of green nanochemistry, we present our experimental findings on the use of the Leidenfrost drop as an overheated and charged chemical reactor. Employing a droplet of aqueous solution on hot substrates, this method is capable of fabricating nanoparticles, creating nanoscale coatings on complex objects and designing porous metal in suspension and foam form, all in a levitated Leidenfrost drop. As exemplar potential application of Leidenfrost drop, fabrication of nanoporous black gold as a plasmonic wideband super absorber as well as superhydrophilic and thermal resistive metal-polymer hybrid foam are demonstrated. We believe that the presented nanofabrication method is a promising strategy towards the sustainable production of functional nanomaterials.
