Blast That Cures

How does this device work?


There is a phenomenon in nature called shockwave. For example, in a volcanic explosion most of the energy is carried away by a shock wave. Whenever such a wave travels through any medium, it increases the pressure and temperature within microseconds. A big Pokhran blast, for instance, would involve 150 kilo tonnes of explosives, but in the laboratory we spend little energy. When we create a blast, a tiny wave of low supersonic speed is produced. The mechanical impulse generated pushes the drug into the body without a needle.
