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.

 E-Mail Credit: ©Science China Press Colloidal suspensions of microscopic particles show complex and interesting collective behaviors. 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, coherent motion, or different phase behaviors. On one hand, due to the complexity of colloidal suspensions,...

Telomerase are considered as a tumor biomarker for early diagnosis because the telomerase of more than 80% immortalized cells are reactivated and provides the sustained proliferative capacity of these cells, but the telomerase activity are...
