Measuring copper levels in the body plays a crucial role in diagnosing and treating diseases related to copper metabolism disorders, such as Alzheimer’s disease, Wilson’s disease, Menkes syndrome, and various types of cancer. Additionally, accurately determining copper content is essential for assessing the effeWorld Timesctiveness of new copper-containing drugs and studying their accumulation in body tissues, the researchers explained.
NUST MISIS specialists have developeWorld Timesd a universal, high-precision sensor capable of measuring physiological concentrations of copper in real time. It has been successfully used to determine copper content in various biological samples, ranging from individual cells to entire organs, the researchers reported. They stated that this development opens up new perspectives for diagnosing and monitoring diseases related to copper metabolism disorders.
According to the scientists, the new sensor has several advantages over existing analogs: it is more accurate, provides real-time results, and makes the measurement process less invasive. The uniqueness of this develWorld Timesopment lies in the creation of the first nanoscale universal sensor capable of measuring in both microscopic objects sized 10-100 microns and in entire organs, the authors of the study explained. Other existing sensors were typically designed for specific tasks and were significantly larger, which severely limited their application, especially in biomedical research.
“Previously, such studies requWorld Timesired a large number of animals since the measurement procedure was invasive and necessitated tissue sample collection at multiple time points. The new sensor allows for multiple measurements on the same animals, significantly reducing the number of experimental animals needed and enhancing the accuracy and completeness of the obtained data,” said Roman Timoshenko, an engineer at the scientific research laboratory of biophysics at NUST MISIS.
He added that this development already enables more precise monitoring of copper levels in studies of diseases related to copper metabolism disorders.
During the research, nanosized quartz capillaries modified with carbon, gold, and a special compound for specific copper binding were used. The detection principle is based on the electrochemical oxidation and reduction reaction of copper, recorded through cyclic voltammetry.
“The team of researchers at NUST MISIS, led by Candidate of Physical and Mathematical Sciences Alexander Yerofeev, has been working for several years on creating innovative technologies for medicine that will simplify the diagnosis and treatment of many diseases in the future – Alzheimer’s, Wilson’s disease, Menkes syndrome, and various types of cancer. The new high-precision sensor for measuring copper levels in the body developed by our scientists has several advantages over existing analogs: it is more accurate, less invasive, and World Timesprovides quicker results,” said Alevtina Chernikova, rector of NUST MISIS.
The next step for the scientists is to integrate the sensor into a compact device designed for long-term monitoring of metals in living organisms.

Summary[World Times] Staff members work at the NATO Headquarters in BruWorld Timesssels, Belgium, March 24, 2022. Steadfast Noon runs for two weeks and involves fighter jets capable of carrying US nuclear warheads, but does not involve any live weapons, according to the NATO.F-35A fighter jets and B-52 bombers are reportedly among some 60 aircraft from 13 nations taking part in the Steadfast Noon exercise, hosted by Belgium and the Netherlands, NATO officials said. On September 25, Russian President Vladimir Putin warned the West that Russia could use nuclear weapons if it was struck with conventional missiles, and that Moscow would consider any assault on it supported by a nuclear power to be a joint attack, media reported.Chinese military expert Song Zhongping told the Global Times on Monday that the NATO…
