Cardiovascular diseases (CVDs) are the leading cause of death globally. Monitoring of lipid in patients with coronary heart disease (CHD) is important for decreasing the incidence of cardiovascular events. The traditional indicator, Low-density lipoprotein cholesterol (LDL-C), is prone to false positives in specific conditions, while invasive routine blood lipid detection fluctuates with the influence of diet, exercise, weight.
Recently, the team led by Prof. HUANG Qing at the Institute of Intelligent Machines, Hefei Institutes of Physical Science (HFIPS) developed a novel biosensor based on aptamer-combined surface-enhanced Raman spectroscopy (SERS) to achieve the inflammatory microRNA-122 (miR-122) detection in cell-secreted exosomes.
Polymeric nitrogen and polynitrogen are believed to be high-energy-density materials. Studies have been conducted to reduce synthesis pressure and improve polymeric nitrogen stability by introducing other elements. However, all patterns of the polymeric nitrogen are negatively charged or covalent bonds are formed between introduced elements and nitrogen atoms by high pressure methods. More research is needed to understand the effects of charge transfer on polymeric nitrogen patterns.
Severe irradiation environment would bring damage to the microstructure of the materials and affect the stable operation and tritium recovery of fusion reactor. Therefore, the efficient tritium production from tritium breeding materials is the guarantee for the realization of tritium self-sufficiency in fusion reactor.
Terahertz (THz, 1011~1013 Hz) related technology, due to its superior spectral performance, possesses wide application potential in communication, security, sensing fields and so on. Its engineering applications highly depend on a variety of THz components.
