  • Applications:
    • Medicine: Nano particles the size of molecules are being used to directly deliver the drug to the diseases part of the body.
    • Electronics: increases the capabilities of electronic goods while reducing their weight and power consumption. Nanomagnets are used like switches, some lasers use a nanopatterned silicon surface that helps produce the light with much tighter frequency control than previously achieved.
    • Solar cells: Nanotech solar cells can be manufactured at significantly lower costs than conventional solar cells.
    • Space travel: Advancements in nanomaterials make lightweight spacecraft and a cable for the space elevator possible. By significantly reducing the amount of rocket fuel required, these advances could lower the cost of reaching orbit and traveling in space.
    • It also finds applications in robotics, fuels, food, chemical sensors, sporting equipment, and fabrics.
