"Researchers have detailed the structure and function of the enzyme styrene oxide isomerase, a tool that enables green chemistry by facilitating the biological equivalent of the Meinwald reaction. This enzyme’s ability to produce specific products with high efficiency and stereospecificity holds significant potential for the chemical and pharmaceutical industries, promising more sustainable and environmentally friendly processes.

Nanotechnology makes it possible to create new types of treatments. In medical use, long and complex molecules make sure. That medicine is released only at the right point. When an enzyme touches the medicine molecule it cuts chemical compounds.
And that activates the medicine. The medicine molecules can equipped with the transportation molecule or enzyme that makes the medicine travel into the right cells. This molecule can be the nutrient that the targeted cells or bacteria eat.
Nanomachines are perfect tools for things like medical treatment. The main problem in those things is how to control nanomachines. The nanomachines are complex molecules that act like machines. The complex molecules require mass production.
Nanomachines can used in medical work. The problem with nanotechnology is how to make sustaining chemical compounds. The second problem is how to make nanomachines select the right cells. And the third problem is how to control those nanomachines.?
And the second problem is how to destroy those molecules at the right moment. If we think of the wheel-looking molecular machines that are above the text, we must understand that the size of those machines is very small. The system can use acoustic whirls to press ions and anions together.
Nano-wheels can destroy bacteria in three ways. The nanorobot can slip into bacteria, and then it starts to rotate very fast. That thing destroys the bacteria's internal structures. The nanorobot can start to rotate very fast and make nanobubbles that can destroy bacteria.
The fast-rotating nanomachine can form a so-called acoustic bubble. When that bubble starts to oscillate. It forms a low-pressure area around its shell. That causes liquid vaporization. And that forms new bubbles. Or the acoustic system can detonate the nanomachine, which makes holes in the cell's shell.
The wheel-shaped nanomachines can used to create nano-size bubbles. The system just makes those wheels rotate so fast that they form supercavitation. Those fast-rotating wheels form nano-size bubbles in liquids. Those bubbles can used to block blood vessels. They can capture viruses or bacteria. And they can used to fill bacteria.
Nano-size bubbles can used in medical solutions. Nanobubbles can close the blood vessels. Researchers can use them them destroy non-wanted cells. The wheel-shaped nanomachines can also create bubbles in the water, and they can destroy bacteria from dirty water, When those machines are not needed anymore, the acoustic system just makes them resonate, and that thing destroys the nanomachine.
