Silver nanoparticles produce a stronger plasmon resonance than gold nanoparticles it can be due to the large reflectivity from the metal surface. TEM images indicate that change in the size of nanoparticles with increasing the laser fluence is in good agreement with the Mie theory.

Magnetic hyperthermia aims to produce the local heating by a magnetically-mediated heating of low-frequency electromagnetic waves, through the power absorption by magnetic nanoparticles. This technique is one of the most important approaches to induce the local heating by low electromagnetic radiation.

The list of common ferrous metal properties include: Durable Good tensile strength Good electrical conductivity Low corrosion resistance Silver in colour Recyclable Usually magnetic Ferrous metals can include a wide range of different alloying elements, including chromium, nickel, manganese, molybdenum, and vanadium, manganese. Are we going down a climate change rabbit hole here? Silver is too expensive. They are using exactly the metals found in the rainwater samples, appearing as Aluminum, Beryllium and Strontium. It has killed several species of plants in my yard both here and in Maryland where I lived when this program began. https://youtu.be/Zbkwjno7T...
