China is located in Eastern Asia and covers a total area of 9,706,961 km2, making it the 4th largest country in the world. In 2019, it had a population of 1.40004 billion, making it the most populous nation in the world.
China’s imports include organic chemicals, oil and mineral fuels, medical and optical equipment, plastics, metal ores, and electrical and other machinery. The country’s exports include data processing equipment, textiles, optical and medical equipment, steel, iron, apparel, and other machinery. The key to China's economic success is the fact that the country is a low-cost producer. This is attributed to a combination of good infrastructure, cheap labor, high productivity, an undervalued exchange rate, and favorable government policies.

In February 2015, Chinese researchers achieved a major breakthrough in nanocarrier drugs for pancreatic cancer. The new multi-layer hybrid nanocarrier developed by the research team achieves the layered carrying of three active pharmaceutical agents. This bridges the technology gap for the application of a nanocarrier as part of multi-drug treatment of pancreatic cancer. The new nanocarrier also significantly improves tumor targeting and the effectiveness of the drug while reducing its toxicities. The research findings have been published in the journal Advanced Functional Materials.
Researchers from Fudan University invented a nanolithium titanate material with high electronic conductivity. This material is highly suited to improving the safety of lithium-ion batteries and is also suitable for usage in solar and wind energy road lights whose lithium batteries need to be replaced every 15 years, unlike the conventional lithium-ion batteries that need to be changed after every two years.
Chinese researchers from the Inner Mongolia University of Technology have analyzed ‘nano-scale deformation of a crack tip’. Through this study, researchers have analyzed nanoscale deformation fields of crack-tips and in turn, developed a new method to analyze the deformation of crack-tips at a very small scale.
Researchers present at the 6th International Conference on Nanotoxicology, held in Beijing in September 2012, emphasized the need for an increase in nanomaterials-based safety studies and improvements in regulatory oversight of synthetic nanomaterials. These implementations are expected to increase the nanotechnology sector in China, promote China’s export of nanotech products, and ensure the safe use of nanotechnology in all walks of life.
China and the US are looking to increase their bilateral R&D cooperation following a meeting between Chinese President Xi Jinping and US President Barack Obama. This follows on from 2012, a year in which US researchers collaborated on more research papers than the next four highest nations combined (Japan, UK, Germany, and Australia).
Chinese researchers contributed to a paper that reveals how the dynamic lithiation process of anode materials such as SnO2 nanowires takes place, using aberration-corrected scanning transmission electron microscopy. This new study provides a new level of understanding of the lithium-ion battery industry.
Chinese researchers have also collaborated with Norwegian researchers at the Centre for Integrated Petroleum Research on a project that revealed as much as 50% of the residual oil from abandoned oil wells can be retrieved using elastic nanoparticles.
Researchers at the Renmin University of China have developed a versatile and readily scalable approach to fabricate a cheap and sensitive paper gas sensor based on single-walled carbon nanotubes.
Meanwhile, another team at The University of Science and Technology of China have developed a reversible contraception method for males that uses gold nanorods in a non-surgical procedure. The technique involves injecting gold nanorods into the testes and heating with an infrared laser. Testing identified reduced fertility in mice and an expectation it may work to treat tumors.
China's science, technology, and industry system has changed from a Soviet-style science-based R&D system to a firm-centered market-based innovation system. China's gross expenditure on research and development (GERD) doubled in the period 2005-10 to 179 billion US dollars or 1.77% of GDP. In 2009, their expenditure on R&D was the second-highest in the world after the USA.
China’s open-door policy has helped attract foreign investment, including capital and technologies. This has also encouraged international collaboration which has no doubt helped accelerate technological development, providing access to foreign expertise and infrastructure.
China also has a medium and long-term plan for science and technology which provides a blueprint for their conversion to an innovation-driven economy by 2020, with expenditure on R&D to reach 2.5% of GDP.
There is no doubt that China is very active in the area of scientific development and nanotechnology. Their willingness to embrace collaboration, the large number of researchers and a commitment to a knowledge-based economy is expected to cement China as a leading country for nanotechnology research.
