Faster, Cheaper Way to Measure Cholesterol Discovered

Cholesterol disease, which occurs as a result of excessive consumption of animal foods, fast food containing trans fat and fried products, has been seen in most people over the age of 40 for the last 30 years on average. The reason for this is that the consumption style we mentioned above has become widespread.

Cholesterol detection is currently colorimetry, chromatography and enzymes However, these methods require either extremely aggressive reagents or complex and expensive equipment. The new alternative that scientists have come up with is that this situation their difficulties seems to remove it.

Invented new device can detect cholesterol much cheaper and faster than normal

Associate Professor from UrFU Analytical Chemistry Department Andrei Okhokhoninexplains the key discovery behind the invention: “We discovered that copper chloride, one of the most affordable options, is highly sensitive to cholesterol.”

Scientists’ invention requires a small amount of blood to detect cholesterol levels, that’s all. Sample blood is collected in a solution of copper chloride in acetonitrile. to the analysis chip is placed. This chip, which contains an electrode connected to the voltammetric analyzer, gives the analysis results in this way.

The new chip’s ability to analyze cholesterol levels also includes magnetic, with molecularly imprinted polymers that selectively absorb cholesterol while filtering out other blood substances important to blood composition. nanoparticles It also has the advantage of inclusion.

The 3D printing of the microfluidic chip, in which all the elements of the system are integrated, also facilitates the production process of the device and makes it faster. Scientists state that their first test was not done on biological samples, but on model solutions that mimic blood serum. The next stage of the researchers’ work will be to test the system on real blood samples.
