Put the micro algae robots into the body to spy on and treat cancer

Micro robots made from . spirulina can be remotely controlled to search for cancer cells and transport drugs to destroy them. Done the task, they will decompose themselves.

A multinational study has released a micro device called "biohybrids" , a hybrid version of high-tech robots and. They are created with the aim of going into the body to find, diagnose and treat diseases in parts that current techniques are difficult to access. Cancer is the central goal of research.

This special robot is made from Spirulina (commonly called) , coated with extremely small magnetic iron particles and can be controlled remotely. Professor Li Zhang, an engineer at Chinese University of Hong Kong, said Spirulina could be said to be a natural material of nature. External fluorescence in algae and iron oxides helps scientists track elements in the body with fluorescent images and magnetic resonance images.

Professor Kostas Kostarelos, from the University of Manchester (UK), another member of the research team, said the robots could capture very small changes in the body in relation to the onset of disease, Become a useful rescue tool for early diagnosis.

In addition to their body scouting duties, they can carry drugs to distribute directly to cells, such as drugs used to kill cancer cells. Done the task, this will biodegrade.

Spirulina is a familiar plant discovered in 1960 in Lake Chad, Central Africa. Today, many countries develop this algae to produce supplements. Spirulina algae has been recognized by leading agencies as the World Health Organization, the US Food and Drug Administration . as "super food" to protect health.
