Come 2010 and we have another invisibility cloak technology knocking on our doors to be embraced. Continuing the illusionary invisible cloaking technique from Harry Potter books, Ji-Ping Huang and colleagues from Fudan University in Shanghai, China, theorize a technique of suspending silver-plated nanoparticles in water to create soft and flexible metamaterial, that forms an ingredient of an invisibility device.

The developed technique or fluid to be specific consists of 10 nanometres magnetite balls, stuffed in a 5nm layer of silver, which self-assemble into chains introduced to a magnetic field, thus forming columns and chains towards the magnetic attraction. A vertical orientation of this sort in water would direct light around an object, cloaking the part inside, thereby making it appear as if nothing is there.
The theory has been appreciated by the scientist around the world but the skepticism lies in the fact whether Ji-Ping Huang and his team would be able to extend this orientation across the entire visible spectrum without showing up any dark spots?
