New Physics: Gradient-Field Raman Effect. Low efficiency of the Raman scattering. Low throughput of the SNOM Fiber probes. Very long acquisition times for Imaging purposes. High mechanical and thermal stability are required. Investigated Samples: Tetracyanoquinodimethane (TCNQ) crystal showing surface...

1. A method to increase the sensitivity of the Raman effect by multiple orders of magnitude, allowing detection of one or more trace molecules that are exuded from a chemical compound of interest and present in a medium, thus enabling a real-time, stand-off sensor, comprising: selecting as ...
Recyclable chipDue to enrichment effect of Mercury ions (Hg), even if the concentration of Hg is very low, it will do harm to human health. Precise detection of trace Hg is important for environment protection and human health monitoring. In this work, gold nanoparticles (AuNPs) are ...
