Can ultraviolet rays kill coronavirus?

Scientists at Penn State and the University of Minnesota have claimed that they have developed new technology that can be used to make hand-held lamps that can kill the corona virus. Such machines still exist, but they are so heavy that it is difficult to carry them anywhere.

However, scientists have discovered a new class of conductors for this purpose which does not consume much electricity. It can be used to free entire theaters and sports stadiums from the corona virus.
