In the last 30 years, superresolution in optical microscopy has been a major field of research. During this time, different techniques have been created to break the diffraction limit in order to make observations at a nanometric scale. Given that optical ...

Microfluidics and optofluidics have revolutionized high-throughput analysis and chemical synthesis over the past decade. Single molecule imaging has witnessed similar growth, due to its capacity to reveal heterogeneities at high spatial and temporal resolu ...

We demonstrate imaging through a turbid layer by using digital phase conjugation of the second harmonic field radiated from a beacon nanoparticle. We show that the phase-conjugated focus can be displaced from its initial position by illuminating the same r ...

Stimulated Emission Depletion (STED) microscopy enables subdiffraction resolution in the imaging plane. However, STED's lateral improvement in resolution is generally better than the enhancement in the axial direction. Here, we combine conventional STED su ...
Multimode fibers have recently been demonstrated to be a promising candidate for ultrathin and high resolution endoscopy. However, this method does not offer depth discrimination for fluorescence imaging and the numerical aperture of the fiber limits its r ...
We report Stimulated Emission Depletion (STED) imaging of green fluorescent nanodiamonds containing Nitrogen-Vacancy-Nitrogen (NVN) centers with a resolution of 70 nm using a commercial microscope. Nanodiamonds have been demonstrated to have the potential ...
