Nanophotonics is the study of light-matter interactions between light and objects on the nanometer scale. In this article, we cover what nanophotonics is used for.

Metalenses are flat lenses that use metasurfaces to focus light. The metasurfaces are a series of artificial antennae that manipulate the optical response of the incident light, including its amplitude phase and polarization.

Slow reaction kinetics and undesirable parasitic reactions have hampered the development of aprotic lithium-oxygen (Li–O2) batteries with ultra-high theoretical specific energies.

In particular, the collective dynamics of colloids is fundamental and ubiquitous for materials assembly, robotic motion, microfluidic control, and in several biological scenarios. The collective dynamics of confined colloids can be completely different from that of free colloids: for instance, confined colloids can self-organize into vortex structures, coheren...

Telomerase are considered as a tumor biomarker for early diagnosis because the telomerase of more than 80% immortalized cells are reactivat...

Credit: @Science China Press Cancer is the second leading cause of death in the world. The number of deaths and incidences is increasing each year. The metal-based anticancer drugs were used clinically worldwide, but suffer from poor selectivity, serious side effects and drug resistance. Tumor-targeting drug development is the basis for precise cancer treatment. Recently, Professor Hongke Liu of Nanjing Normal University, Professor Jing Zhao and Academician Zijian Guo of Nanjing University hav...
