Molecular device turns infrared into visible light
Our group, in collaboration with Wuhan Institute of Technology, the Valencia Polytechnic University, and AMOLF in the Netherlands, has now developed a new way to detect infrared light by changing its frequency to that of visible light. The device can extend the “sight” of commonly available and highly sensitive detectors for visible light far into (…)
Toward a diamond sensing platform for measuring neuronal activity
Our group, in collaboration with the EPFL School of Engineering, Institute of Electrical and Micro Engineering and the EPFL School of Life Science, successfully demonstrates growth of a network of living and functional primary mouse hippocampal neurons on a nanostructured single crystal diamond surface. Our results suggest that neuron growth can be tailored on diamond (…)
Measurement-induced collective vibrational quantum coherence under spontaneous Raman scattering in a liquid
Spontaneous Raman scattering is classically understood as an incoherent process. Here, we evidence that a macroscopic quantum coherence among billions of vibrating molecules is generated when detecting a single Stokes photon collected into a single-mode fiber. Our results show that at the quantum level spontaneous Raman scattering is an intrinsically collective effect, even in the (…)
