What is O18-labelled carbon dioxide?
O18-labelled carbon dioxide is a type of carbon dioxide that contains the oxygen isotope 18O.
What are the applications of O18-labelled carbon dioxide?
By using O18-labelled carbon dioxide, scientists can trace and study the pathways of gas exchange during plant photosynthesis, as well as the process of carbon cycling through the ecosystem.
O18-labelled carbon dioxide is mainly used in scientific research, medicine and environmental monitoring. This labelled carbon dioxide has important applications in scientific research, particularly in the fields of biology and earth sciences.
Specific areas of application are:
1. Scientific research: O18-labelled carbon dioxide can be used as an isotopic tracer to trace the metabolic processes and pathways of compounds and biomolecules. This is particularly important in biochemical research as it helps scientists to understand the reaction mechanisms in complex biological systems.
2. Medical aspects: In the medical field, O18-labelled carbon dioxide can be used for the production of radioisotopes in positron emission tomography (PET), in particular for the production of the medical radioisotope fluorine-18, which is of great value in clinical diagnosis and disease research.
3. Environmental monitoring: By analysing O18-labelled CO2, scientists can better study and understand the carbon cycle in the atmosphere and related climate change issues. This will enable more accurate climate models and deeper analysis of phenomena such as global warming.
4. Geological research: In geological research, O18-labelled carbon dioxide can also be used to study the Earth’s palaeoclimate by analysing the isotopic composition in ice cores or rock samples to reveal past climate conditions and trends.
5. Bioengineering: In the field of bioengineering, O18-labelled carbon dioxide can be used to study the metabolic activity of microorganisms, helping to improve industrial fermentation processes or develop new biotechnology products.
6. Chemical research: In chemistry, O18-labelled carbon dioxide can be used as a reactant or tracer to study the mechanism and dynamics of chemical reactions.
7. It can also be used to study the source and formation of groundwater, and in the medical field to study metabolic processes in the human body.
When conducting experiments with O18-labelled carbon dioxide, scientists often combine it with other labelled substances to better understand the pathways and mechanisms of chemical reactions.
