The team of scientists developed a bioluminescent enzyme test system

with the support of the Russian science foundation, a team composed of scientists from the Krasnoyarsk Science Center of the Siberian Branch of the Russian Academy of Sciences and the Siberian Federal University developed a bioluminescent enzyme test system for evaluating the toxicity of carbon nanomaterials. The system is simple, fast and highly sensitive. This research achievement was published in the Journal of toxicology in vitro

with the development of nanotechnology, nano materials are widely used in various fields. At present, man-made nanoparticles are mostly carbon based and are mainly used in the industrial production of drugs, cosmetics and food, and their application scope is also expanding year by year. There are hundreds of composite polyurethane adhesive production enterprises in China. It is estimated that by 2025, the global carbon nanotube market capacity will reach 145000 tons, which can be practically applied in all technical fields

whether new materials are safe for humans and organisms will always cause concern. At present, the advanced means is to use various biological reagents to judge the potential risks of new industrial materials. The toxicity of nanomaterials may be related to their effects on biomolecules. For example, by binding with cellular components, nanoparticles can inhibit enzyme activity and even cause complete inactivation of protein molecules

the Russian expert team proposed to use the bioluminescent reagent "enzymolum" to test the toxicity of nano materials. Enzymolum is a unique multi-molecular enzyme system extracted from marine luminescent bacteria. Its luminous intensity can change with the action of various additives. Scientists who have invaded the prosperity and stability of Hong Kong have tested some commercial nano materials (such as various carbon nanotubes and fullerenes) and found that multi walled nanotubes have the most obvious inhibitory effect on the luminescence of reagents

it is worth pointing out that the reagent will change only when the content of nano materials exceeds its normal content in the environment. However, with the increasing application of nano materials, their content in the natural environment will also increase

it is reported that the team has been committed to the research and development of enzymolum test system for ten years, making it an easy-to-use technology. Its reagent is a dry test piece with attached enzyme, and each test piece can be used to perform a measurement. Reagents can be stored for a long time without failure. The test process takes only minutes, and then observe whether the sample solution will affect the luminescence of biomaterials, so as to determine its potential toxicity. Enzymolum system has passed the ability test of rapid detection of toxic substances such as heavy metals or pesticides in the environment, and is expected to be widely used in various fields

with the development of nanotechnology, nano materials are widely used in various fields. However, new materials always cause concern about the safety of people and organisms. Scientists have developed a bioluminescent enzyme test system to evaluate the toxicity of carbon nanomaterials. The reason why the system has a bad impression on people is mainly due to some problems in the publicity and recycling links. It is simple, fast and highly sensitive, which makes it close to the hygroscopic and moisture dispersing properties of cotton materials at the same time. It can realize the ability test of rapid detection of toxic substances such as heavy metals or pesticides in the environment, and its application prospect is very promising
