We demonstrate that optical third-harmonic generation (THG) microscopy enables high-resolution live brain imaging without the need for external contrast agents. We find that the specific geometry and ...

Abstract Coherent anti-Stokes Raman scattering (CARS) microscopy can resolve the chemical components and distribution of living biological systems in a label-free manner and is favored in several ...

Here, based on the characteristics of Graphene oxide(GO) and SYBR Green I(SGI) dye, an enzyme-free and label-free fluorescent biosensor with signal amplification through DNA strand reaction is ...
