1 nanometer is equal to 0.000001 millimeters. In the invisible nano 'battlefield', Li Wei, director and researcher of the Nanomedicine Research Laboratory at a certain center of the Naval Medical University, has been leading the charge for more than ten years and has developed a series of innovative military nanomedicine technologies. Not long ago, Li Wei's English monograph "Nanophysics Pharmacy" was published. Hou Huimin, academician of the CAE Member, commented that this is the first English monograph in the field of international nano physical pharmaceuticals, which provides important theoretical support for promoting the clinical transformation of high-end preparations and pilot scale quality control. Li Wei, who comes from a background in science and engineering, has always had a strong interest in advanced material technologies such as nanotechnology, as he takes on the heaviest burden and gnaws on the hardest bone. In the late 1990s, he successively studied for a master's degree in inorganic chemistry at the University of the Chinese Academy of Sciences, a doctor's degree in polymer physics at the Chinese University of Hong Kong, and later engaged in post doctoral research in applied biology at the Hong Kong Polytechnic University. At that time, Li Wei discovered that many developed countries had already applied nanotechnology, but related research was still in its infancy in China. He wants to engage in related research work in China and shift the focus of scientific research to this field. In order to learn nanotechnology, he decided to continue his studies. In 2010, after completing his studies, Li Wei received several "olive branches" from research institutes and universities. At this time, Wu Qi, a tutor of Li Wei and an academician of the CAS Member, took out a recommendation letter and told him that the Naval Military Medical University wanted to introduce a nanomedicine expert. Li Wei, born in the revolutionary old area of Qianshan, Anhui, has always had a dream of joining the army and serving the country. At the age of 36 at that time, he thought he would never have the chance to join the military camp in his life, but he didn't expect the opportunity to be right in front of him. I want to work at a military academy and serve the army, "he said. In the autumn of 2010, Li Wei joined the People's Army as a civilian. At that time, the nano research equipment in Li Wei's unit was relatively scarce. He led the team to build the only nanotechnology application platform in the entire army, working until late at night every day and often living in the laboratory. The job of 'going from 0 to 1' is the most difficult. We have to shoulder the heaviest burden and gnaw on the hardest bones, "said Li Wei. Two years later, Li Wei led the establishment of a leading military nanotechnology research platform in China. In 2013, the laboratory urgently needed to update its instruments and equipment. Li Wei voluntarily gave up the portion of the achievement transfer fee that was rewarded to him personally and invested all of it in laboratory construction. After completing the construction of the laboratory, Li Wei led his team members to immerse themselves in thousands of reagent and sample piles day after day, calculating one complex physical formula after another. If we make breakthroughs in basic theory, we can promote the application of nanotechnology in the military field, "said Li Wei. For the next 8 years, Li Wei devoted himself wholeheartedly to fundamental research. To succeed in a career, one must endure loneliness, "Li Wei and his team members often use this phrase to encourage each other. Others advised Li Wei to develop products, but he was obsessed with studying the scientific principles behind nanotechnology. Without fundamental theoretical breakthroughs, it is difficult to achieve technological breakthroughs, "said Li Wei. After 8 years of research and development, the Li Wei team has cracked the 7 key parameters of nanotechnology and derived 8 customized technical formulas for nano products. On this basis, they independently developed 5 sets of process equipment, among which the nano performance research equipment under dynamic blood flow conditions has reached the world's leading level. In 2020, the original achievements of Li Wei's team were published in the international journal Nanomedicine. An internationally renowned nanomedicine expert commented on this: "This young man has opened the 'black box' that determines the customization theory of nanosystems." "The results have been applied in practice, giving me a sense of achievement." In the autumn of 2021, Li Wei discovered that some soldiers of a submarine detachment had experienced a relapse of skin diseases. The reason is that in the enclosed environment of submarines, bacterial communities are prone to developing drug resistance. So, Li Wei used nanotechnology to change the molecular composition of antibacterial drugs, allowing the drugs to act on the affected area for a long time. He also developed nano disposable antibacterial wet wipes and skincare creams suitable for special environments such as submarines, which are highly welcomed by officers and soldiers. Afterwards, Li Wei turned his attention to the prevention and control of marine biological pollution, using nanotechnology to "reduce the burden" on ships. Marine organisms that adhere to the bottom of a ship for a long time not only corrode the hull, but also affect its navigation speed. After discovering this issue, Li Wei led a team to develop a nano bio simulation coating based on ships using nanotechnology. In order to verify the effectiveness of the coating, Li Wei contacted a coastal fishing boat repair shop, went to the factory to paint the fishing boat, and recorded various parameters of the boat's hull after it went into the sea. The "stream" of scientific research and innovation gradually merges into the "tide" of building a strong and prosperous military. Li Wei's scientific and technological achievements, which can be applied to the exterior of ships, such as nano biological simulation coatings, high-temperature and high-altitude anti seawater nano agents, and antibacterial coatings for ship ventilation systems, have been applied to the front line of the military. He said, "I feel a sense of achievement when the achievements are translated into practical applications." In recent years, Li Wei has been rated as the "elite of naval transformation" exemplary individual and elected as the representative of the Navy Party Congress. Dressed in peacock blue, he is accelerating on the military research track. (New Society)
