The work of our body hemoglobin is quite simple: it is the transport of oxygen molecules in blood vessels. But it just works so much that the hemoglobin molecule is very difficult. The same applies to chlorophyll, which transforms plants into solar energy.
To understand the sophisticated tricks of such complex molecules, the lab is similar to simple but simple structures research. TU Wien (Vienna) and Trieste Research Group have already studied fluolivekines, whose molecular structure is similar to the hemoglobin or chlorophyll sections. It turned out that the center of this seal can be moved to different countries with the help of green light that affects their chemical behavior.
Not only does it help to understand the biological processes, it also explains new opportunities for laboratories for other purposes – a strategy called "biomimics" which is becoming increasingly important in the world.
Rings with metal atoms in the center
"The fluocyclines that we will study with the color of the typical printed prints," said Professor Günter Ruprepter of the Institute of Material Chemistry at Vienna Technology University. "The most important element of the structure of this seal is that the iron atom in its center – hem, rice pigment red hemoglobin." On the other hand, chlorophyll has magnesium atoms.
In contrast to the more complex natural molecules, the custom made fluolskinine paints can be regularly placed on the surface, such as bathroom wall slabs. "The rings were placed in a regular pattern for graphenes to create a two-dimensional crystal of paintings," says Matteo Royise, who has experimented with Christoph Ramshan. "This is the advantage that we can examine many molecules at the same time, which gives us much more measuring signals," explains Christoph Ramshen.
Carbon monoxide molecules serve probes in the investigation of these rings: one molecule can attach metal atom, which is held in the center of the ring. From the vibrations of carbon monoxide molecules, you can get information about the metal atom level.
To study vibration, the molecule is laserized with laser light – using a combination of green and infrared light. This measure resulted in a sharp contrast: "We did not have just a vibrational frequency of carbon monoxide, instead we had four different frequencies, nobody expected," says Guenter Ruppter. "Iron atoms are all identical, so the molecules attached to them must show the same behavior."
As it turned out, the laser green light was responsible: first of all iron atom is really identical, but the green light can interact with different countries. "This also changes the frequency of the CO 2 molecule on iron atom, which shows how sensitive these structures respond to the small changes," says Gunter Rupperter. "This is also a bio-molecule structure in our bodies: the widespread protein components have the least impact on metal atoms, but these minimal impacts can have very important consequences."
Measurement at room temperature and atmospheric pressure
Similar effects can only be studied at extremely low temperatures and ultrahigh vacuum. "We have two methods in the laboratory, where such biologically relevant events can be measured at room temperature and atmospheric pressure and without green light", – emphasizes the Ruprechtster. It opens up new possibilities to better understand the chemical behavior of biological substances; He was also able to create the molecules of the novelists in order to optimize them for the specific nature of nature.
