RT published this video item, entitled “Spray that turns objects into robots?!” – below is their description.
SA group of Honk Kong scientists and researchers led by Associate Professor of the Department of Biomedical Engineering at the City University of Hong Kong, Dr Yajing Shen, developed a magnetic spray that has the ability to transform small objects into moving millirobots, as filmed in the University laboratory on Wednesday. The so-called “M-spray” is a glue-like matter, consisting of PVA (Polyvinyl alcohol), gluten and magnetic particles. An object coated in the M-spray can then be manipulated by magnetic fields, causing them to move on different surfaces, as Shen’s student demonstrated. The movement of these millirobot is then controlled through the magnetic field which then affects the magnetic particles from the spray. ubscribe to RT! https://www.youtube.com/channel/UCpwvZwUam-URkxB7g4USKpg?sub_confirmation=1 RT LIVE https://www.youtube.com/watch?v=IFAcqaNzNSc Check out http://rt.com Like us on Facebook http://www.facebook.com/RTnews Follow us on VK https://vk.com/rt_international Follow us on Twitter http://twitter.com/RT_com Follow us on Instagram http://instagram.com/rt Follow us on Soundcloud https://soundcloud.com/rttv #RT (Russia Today) is a global #news network broadcasting from Moscow, London, Paris and Washington studios to over 100 countries.

Hong Kong, officially the Hong Kong Special Administrative Region of the People’s Republic of China (HKSAR), is a metropolitan area and special administrative region of the People’s Republic of China on the eastern Pearl River Delta of the South China Sea. With over 7.5 million residents of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is one of the most densely populated places in the world.
Hong Kong became a colony of the British Empire after the Qing Empire ceded Hong Kong Island at the end of the First Opium War in 1842. The colony expanded to the Kowloon Peninsula in 1860 after the Second Opium War and was further extended when Britain obtained a 99-year lease of the New Territories in 1898. The whole territory was transferred to China in 1997. As a special administrative region, Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of “one country, two systems”.
