A latest information of nanotechnology and it application is the nano antenna. A nano transmitter/antenna is a small antenna which can receive signal from light/flash and this transmitter is capable of receiving the signal from remote source.
Recently a research team from Australia invented a small transmitter which can receive light/flash signal instead of sound wave.
The researchers claim that using this antenna it is possible to make security related software which is capable of detecting drug and explosive.
A research team from Swinburne University said that this tiny antenna can do all other function of a typical antenna but the specialty of this transmitter is that it works with the signal of light instead of sound wave.
