As a biochemist, I find it very interesting to learn about the type of results one would get and use for further experiments with NMR and proteins. Considering that proteins are giant molecules that are intricately connected to serve a special function, I am quite curious to see how NMR can be used to study protein structure, down to the molecular level.

@MariaBaiasHeritage

There's a lot of high field NMR research, both in solution-state and in solid-state NMR, that's done on proteins to learn about both the protein structure and the protein dynamics. And some of these studies are done on really big proteins and in order to study such large systems we use many different types of multi-dimensions NMR experiments in combination with selective labeling of certain atoms in the protein so that we observe fewer resonances at once in an NMR spectrum. In my past research I worked on the protein responsible for the Huntington disease.

Through this video I learned that NMR is a very powerful technique of analysis of organic compounds. I would love to learn more about its application in the analysis of food. Being a foodie, it is very important for me to balance my diet in a way that is both healthy and tasty. I think through NMR, we can identify compounds in food which my not be beneficial to humans thus providing me an in-depth analysis of what I'm eating. Furthermore, the use of NMR in the food science industry would benefit consumers by analyzing the safety of food products before they are launched in the market. Food is a very important part of everyday life and I would love to learn about it as an application of NMR.

The NMR Application that I would like to learn more about is the study of degradation of objects of cultural heritage using Nuclear Magnetic Resonance. In the video, we learned how NMR can be used to determine the chemical composition and chemical environments within samples by observing magnetic fields around atoms. I think it would be interesting to learn more about what kind of molecular changes and chemical environmental phases an object goes through during degradation. For instance, is there a specific order or pattern of changes in chemical structure, state, or properties a substance goes through during degradation that we can analyze using NMR? And what clues from NMR will let us know how old an object is? It would also be nice if we could see some historical examples in which NMR helped mark the age or era of the sample.

@MariaBaiasHeritage

We can use NMR to look at the chemical composition and local atomic environment with we use NMR spectroscopy. We'll talk more about the degradation of heritage and historical objects when we look at case studies of mobile NMR because we prefer to use mobile NMR when it comes to cultural heritage because mobile NMR is non-invasive and, as much as possible we prefer not to remove samples for heritage objects for experiments. Unfortunately we can't tell the exact age of an object using mobile NMR, but we can identify signs of aging and sometimes say the relative age of an object with respect to another one.

Among the applications of NMR mentioned in this video, I am most interested in knowing more about how this technology is used to study the human body and human behaviour. The MRI scanner is often used in psychological experiments, and it has yielded many insights about the brain. I wonder if this technology can be applied to the study of other body parts such as joints, which are incredibly complex in their structure and especially relevant to our daily lives.

Yes, MRI can definitely be applied for the study of body parts and you can get really nice images of of the body using the MRI scanner. As for the brain, you can get the anatomical structure of the brain imaged by MRI, and using the same scanner, just different NMR experiments you can do the functional MRI and look at brain activity. Truly fascinating!

Even though it requires very costly materials make use of, would it be distributed in many parts of the world? Also, I specifically want to know whether Helium cannot be replaced with other elements that also keep its aqueous state in the environment the Helium atoms are placed in.

@MariaBaiasHeritage

3 жыл бұрын

You can find NMR magnets in many parts of the worlds, lots of universities have NMR magnets for research and different companies working in materials research, pharmaceuticals and other R&D also have NMR magnets. Helium is required for the big magnets to keep the magnet cool because what we call the magnet is a large superconducting coil and it only creates the magnetic field as long as the material is superconducting and the material is superconducting at ver low temperatures. This is why it is kept in liquid helium because the temperature of liquid helium is 4.2 K (-269 °C). There are ways to reduce the amount of liquid helium needed, and the newer magnets use this technology of helium reliquefaction. You still need helium, but you don't need to refill the magnet that often.

Thanks for information. If no pulse is applied, won't the protons rotating in the magnetic field emit any frequency?

There are certain sounds that are coming from the NMR system, like the gradients in imaging systems, but you would only hear those inside the lab and some newer versions of the magnets have a cooling system, but I've never heard of one that would be so loud you would hear it across the street. Maybe it's something else that's making the noise.

Dr. Maria can you please explain NMR application in biology ( DNA , RNA ,... ) ?

@MariaBaiasHeritage

NMR is very useful in biology because of its capability in determining structure and dynamics of biologically-relevant molecules. There are different NMR experiments (both in solid-state NMR and in solution-state NMR) that can be used specifically for structural assignments. These experiments in combination with certain software are used to perform sequential assignments of peaks from NMR spectra (but you need a combination of different sets of NMR experiments) and then that sequential assignment can be used in combination with additional software to predict 3D structures of complex molecules. Similarly, for dynamics you can use other sets of NMR experiments and if you combine them with computational programs you can reveal quite detailed information on the dynamics of certain groups in the molecule (or even full molecule if you also run some molecular dynamics simulations). This is only a very brief overview of what you can do with NMR in biology, but if you're interested in this topic, I highly recommend the ICMRBS KZread channel (kzread.info/dron/sxup-QiNEeBrfo-4d5w33Q.htmlfeatured) which is focused on studying biological systems with NMR. Hope this helps!
