The new light-based technology can turn dugs on and off.

The same system that can activate and deactivate medicines can be used in molecule-based data storage. The reactive tail of the molecule causes an electric impulse that is one for the system and the non-reactive gives zero. The molecules can be upside down and then the light or acoustic impulse turns them around. The non- or less reactive tail gives zero and the higher reactive tail gives one. 

The system where the receiver plays with the voltage levels is easier for the receiver than the case where the molecule doesn't give a voltage at all. There must be something that senses if the certain molecule travels through the reader. The other version is that the laser reads how tall the molecule is. The size of the molecule can determine if it should give one or zero to the receiver. 

The nanoball can also make it possible to create chemical qubits. Those medical qubits store information on the magnetic molecules on the nano-balls. Then laser destroys that ball and sends those molecules to receivers. And each molecule is in a certain state in the qubit. 

Nanotechnology is one of the most impressive ways to make medicines. There is the possibility of making nano-size balls where the medicines or other chemicals are located. The ball itself is made of the nano-net there are the nano-hatches. The light-based nanotechnology can activate and deactivate drugs. The system sends light impulses to the nano-ball surface. 

And that light impulse can open and close the nano hatches on the nano-ball surface. Or the light can remove the non-reactive shell from those molecules. Or the signal can turn the molecule with the reactive tail to the outside. When light deactivates medicine it can turn the non-reactive tail to outside. The acoustic signal can also make similar things. The hatches in nanonet can also make it possible to create medicines that can be active only when needed. The system is like a high-tech laundry ball. 

The system can also use things like acoustic systems to open or close the hatches. The idea is that the nanoball that is near the targeted point faces the acoustic impulse. The low pressure at the opposite side pulls nanohatches open and that can release enzyme-acid combinations. 

Those proteins there is acid molecules on them that can cut the wanted tissue away. The ability to use enzyme-acid combinations as medical tools can make it possible to create new medicines. Things like cancer- and bacteria cells can be resistant to regular antibiotics and cytostatics. However, they cannot resist the acids and enzymes that cut their protein molecules. The ability to activate and deactivate medicines can also be used in other chemicals. 

The ability to activate and deactivate chemicals can have many uses in the chemical industry. The ability to activate and deactivate enzymes and inhibitors makes it possible to advance chemical reaction control. And that can be the new step in fundamental chemistry.

Researchers manipulated atoms and molecules with light. And that makes the new chemistry possible.

The new spectrometers and other systems can observe the purity of raw materials. In the new reaction chambers, those systems can hover between nanomachines. And observe how the system advances the molecule formation. 

The nanodiamonds can act as, or with. The quantum sensor. The sensor is based on the quantum entanglement. And photon scanners can see even the positions of single electrons. The sensor works with the single photons that the system puts to send wave movement. 

Those single-photon scanners are the sharpest sensors that researchers can create. They can used to aim energy impulses into the single electron. This ability means that the system can shoot single electrons out from their orbitals. These kinds of sensors may not be so far in the future. The ultra-fast X- and ultraviolet radiation pulses can used to create the image of the atoms.

If there are channels in the quantum diamonds. Where there are even hydrogen ions (protons) or electrons that can scan the surface with impressive accuracy. In some ideas, the UV system freezes the electron that orbits the proton in hydrogen. Then the system inputs energy into the proton, and the electron acts as a stylus that scans the object.

The ability to see particles. And their chemical bonds. Make it possible to create new chemistry. And that new chemistry makes it possible to create fundamental new molecules that revolutionize medical research. In the same way, those new molecular bonds raise nanotechnology to a new level. 

The ability to order the angle. And the point. Where two atoms, or molecules make contact. Is the thing. That changes chemistry forever. 

Light can blow the electron cloud into one side of the atom. Or a very sharp photon beam can shoot one individual electron away from its position. That thing makes it possible. That system can create chemical bonds for noble gases. 

Light or photonics is the new tool. That can make the new very complex chemical compounds possible. 

The new observation tools and fast-reacting energy-pumping systems along with highly sophisticated neural networks make it possible to manipulate atoms and molecules in new ways. The system can make the ultra-high accurate physical and chemical environment and aim the UV or IR and other monotonic radiation types to the objects with very high accuracy. 

The ability to send radiation into the individual electrons is the thing that makes the system more accurate and fundamental than developers ever imagined. The system can adjust the physical environment with UV and IR holograms. And those things can adjust the energy level in the atoms and their parts with ultra-high accuracy.
