Biological engineers from the University of California at San Diego today presented the results of their long work on the creation of special nanorobots that mimic living cells, whose main function and task is to cleanse blood and biological fluids from dangerous bacteria and their metabolic products. An article with this invention has already been published in the science journal Science Robotics, where a group of researchers led by professor of computer engineering Joseph Wong, noted all the most important and interesting features of the functioning of these nanorobots. Their main advantage is high mobility and the ability to control with ultrasound.
In addition, their very design and structural features allow nanorobots to successfully move into any biological fluids, effectively cleaning them from harmful bacteria and their decomposition products. Representing gold nanoconductors wrapped in hybrid platelets and red blood cell membranes, these nanorobots are controlled by ultrasound, which allows them to be acted upon in an efficient and fast way, eliminating the need to use any chemical fuel to operate them.
This significantly increases the degree of safety of their use in almost any tasks and conditions, not to mention the fact that nanorobots can be used even in cases where the patient has an obstructed flow of blood and fluid in the body. In addition, the team once again proved with their project that wrapping nanoparticles in cell membranes is the best way out!
In modern medicine, there are many problems associated with the correct selection of one or another nanomaterial for use in critical situations when it is necessary to conduct a complete and effective detoxification of the patient's body. It is with the help of the presented concept of nanorobots wrapped in a double layer of cell membranes that it becomes possible to develop a more effective approach to this process.
