Two-Dimensional Analysis Method for Highly Sensitive Detection of Dual MicroRNAs in Breast Cancer Cells

“…As a sensitive sensing technology, dark-field microscopy (DFM) with a high temporal and spatial resolution can be applied in the single-particle imaging analysis . In recent years, it has been widely used in the field of biosensing, − bioimaging, , and chemical reaction monitoring , due to its great performance.…”

“…As a sensitive sensing technology, dark-field microscopy (DFM) with a high temporal and spatial resolution can be applied in the single-particle imaging analysis. 9 In recent years, it has been widely used in the field of biosensing, 10−14 bioimaging, 15,16 and chemical reaction monitoring 17,18 due to its great performance. In the DFM imaging process, information such as the number and relative position of noble metal nanoparticles, as well as the scattering color and its intensity of a single particle, can be obtained for the purpose of biochemical analysis.…”

Fluorescence wavelength shifts combined with light scattering for ratiometric sensing of chloride in the serum based on CsPbBr3@SiO2 perovskite nanocrystal composite halide exchanges

“…17,18 Therefore, for size-dependent fluorescent systems that experience fluorescence quenching or enhancement due to decomposition, aggregation, or plasmons, the aforementioned ratiometric platform can be easily realized based on simultaneous fluorescence and scattering intensity responses to the target. 13,[19][20][21][22][23][24] This innovative strategy provides new insights into the applications of fluorescent ratiometric sensors. At the same time, it also causes us to think about whether we can build a fluorescence/scattering wavelength shift-based ratiometric sensing system, which has never been reported before.…”

The Accurate Imaging of Collective Gold Nanorods with a Polarization-Dependent Dark-Field Light Scattering Microscope

“…In recent years, dark-field microscopic (DFM) imaging has found wide applications in analytical detection − and real-time monitoring − due to its high spatial resolution, which has reached the single-particle level . For example, our group has achieved the detection of biomarkers and the real-time monitoring of the ion motion-induced structural transformations with plasmonic nanoparticles as dark-field light scattering probes. , Plasmonic nanoparticles display a wide range of colorful images under DFM, depending on their sizes, morphologies, compositions, and surrounding environments. , Furthermore, the anisotropic nanomaterials are able to present polarization-dependent dark-field light scattering, which is much different from the isotropic nanoparticles .…”
