Indium (In) Nanoparticles - Properties, Applications

The potential for nanoparticles in medical imaging, industrial applications, disease diagnoses, and several other fields are infinite, and researchers constantly exploring novel applications of nanoscale materials.

Indium is a Block P, Period 5 element. It is a very soft and malleable metal that is sourced as a byproduct during zinc production. The morphology of these particles is spherical, and they appear as a black powder.

Indium nanoparticles are graded as harmful when they come in contact with the eyes and skin, and if swallowed or inhaled.

In general, indium has been used in many semiconducting materials that are used for electronics and other applications like solar cells. Based on this, researchers from the Lund University in Sweden created a novel type of solar cell from indium phosphide nanowires in January 2013. These nanowires match the electrical output of conventional thin-film solar cells and occupy only a fraction of the space.

Other potential applications of indium nanoparticles are in the following areas:

  • As a superconducting material
  • As solder in nanoscale electronics

Researchers are looking at ways to further exploit the nanoparticles’ potential electrical, magnetic, optical, biomedical, and bioscience properties.
