The Increased Use Of Nanotechnology In China’s Biotech Industry
Abstract:
Basic research in nanotechnology is heavily pursued in Beijing. Approximately 30 institutions are intensively engaged in nanotechnology research. Some of them are as follows:
The National Center for Nanoscience and Technology of China (NCNST) in Beijing, was established in 2003 by the Chinese Academy of Sciences and Ministry of Education. In August 2006, NCNST established the China Lab for the Bio-Environmental Effects of Nanomaterials & Nanosafety to focus on the economic, environmental, and social aspects of the research, standardization, and regulations of nanotechnology. One example of research undertaken at NCNST includes Dr. Yuliang Zhao's discovery that C82 nanoparticles selectively kill cancer cells with low unwanted cytotoxicity.
In August 2009, research out of Shanghai Jiaotong University utilized gold nanoparticles as ultrasensitive fluorescent probes to detect cancer biomarkers in human blood. These nanoparticles are promising probes for biomedical applications because they can easily be prepared and, unlike other fluorescent probes such as quantum dots, don't burn out after long exposure to light. The particles detect carcinoembryonic antigen (CEA) and alpha fetal protein (AFP) — two important biomarkers in the diagnosis of liver, lung, and breast cancers.
The Institute for Advanced Materials and Nano Biomedicine (iNANO), located at Tongji University in Shanghai, focuses on intelligent nano systems for medical diagnosis and treatment including cell targeting, drug/gene storage and delivery, in vivo imaging, new bio-probes for fast and quantitative virus detection, environmental monitoring, and food testing, in addition to biomaterials, tissue engineering, cell regenerative medicine, and stem cell biology.
The Suzhou Institute of Nanotech and Nanobionics (SINANO) focuses on the development of nanodevices and systems for high-resolution imaging and biosensing; the development of interfacing techniques for the integration of biomedical devices, microelectronic, and optoelectronic techniques; and the development of drug delivery systems and dosage forms.
In early 2009, researchers from Nanjing University in collaboration with colleagues from New York University developed a two-armed nanorobotic device that can manipulate molecules, thereby enabling the creation of new DNA structures that could potentially be used as a "factory" for assembling the building blocks of new materials.
