Engineers have created a nanodevice for “hunting” for bacteria in human blood

About 700,000 people die every year from antibiotic-resistant infections. Of these, 230 thousand – only from tuberculosis. According to preliminary estimates, this number will increase to 10 million by 2050. The solution can be a small device that can filter bacteria in human blood.

The tasks of the new microscopic device include the detection of bacteria in the blood, which will allow doctors to accurately diagnose dangerous infections and prescribe the right drugs, increasing the patient’s chances of survival.

The created device is able to isolate and remove target bacteria from body fluids. The device effectively filters particles and microbes, capturing about 86% of them. The principle of operation of the device is based on magnetic nano-balls designed to capture bacteria Escherichia coli (E. coli). Small spaces between the balls are used to isolate germs in the device.

Engineers say that the device can be easily manufactured, which makes it ideal for detecting pathogens in laboratory and medical institutions. They are currently working on improving the device, planning to add several additional functions to it.
