Acoustic levitation to help Medicines

Unless you travel into the vacuum of space, sound is all around you every day.. You hear sounds; you don't touch them. But as the vibrations that sound creates in other objects. The idea that something so intangible can lift objects can seem unbelievable, but it's a real phenomenon.

Acoustic levitation takes advantage of the properties of sound to cause solids,and liquids to float. The process can take place in normal or reduced gravity. To understand how acoustic levitation works, you first need to know a little about gravity, air and sound.

First, gravity is a force that causes objects to attract one another. The more massive an object is, the more strongly it attracts other objects. The closer objects are, the more strongly they attract each other.. Scientists haven't decided exactly what causes this attraction, but they believe it exists everywhere in the universe. Second, air is a fluid that behaves essentially the same way liquids do. Like liquids, air is made of microscopic particles that move in relation to one another. Air also moves like water does, in fact, some aerodynamic tests take place underwater instead of in the air. Third, sound is a vibration that travels through a medium, like a gas, a liquid or a solid object. A sound's source is an object that moves or changes shape very rapidly. Each molecule moves the one next to it in turn. Without this movement of molecules, the sound could not travel, which is why there is no sound in a vacuum. Acoustic levitation uses sound traveling through a fluid, usually a gas, to balance the force of gravity. On Earth, this can cause objects and materials to hover unsupported in the air. In space, it can hold objects steady so they don't ...

...nstead of the common crystalline state, something that is extremely hard (gizmodo.com). That’s where the liquid levitation comes in, a machine that uses sound waves to make liquid solutions float. This way the liquid solutions don't touch any solid materials as the water evaporates, solidifying in the much desired amorphous drug, so it can be more efficient in helping.
We can draw to a close that the effect of using sound to levitate medicines and liquids can be more a more effective form of giving and creating medicine, because when the amorphous state of medicine touches an object it starts to turn into crystalline state which doesn’t supply as much effectiveness, not only for effectiveness but also in the speed of disbursement. so inturn using acoustic levitation takes out the step that causes it to turn into crystalline state, in turn increasing effectiveness.
