Scientists fabricate anticancer nanoparticles by recreating deep sea volcano chemistry
James Strachan |
Current methods for fabricating nanoparticles, such as hydrothermal synthesis, laser ablation, or gel synthesis, all involve environmentally unfriendly surfactants, as well as expensive instrumentation. But what if fabrication could be achieved simply with a water bath and hot plate? Inspired by the way water dances on a hot pan – the Leidenfrost phenomenon – and similar chemistry that takes place in underwater volcanos, Mady Elbahri, Professor of Chemical Engineering at Aalto University, Finland, has developed an environmentally friendly means of producing ZnO2 nanoparticles (1). What’s more, Elbahri’s team has also found that the nanoparticles can kill cancer cells. Here, he tells us more about Leidenfrost nanochemistry.
