Objective(s): Nanomaterials are playing major roles in imaging by delivering large imaging payloads, yielding improved sensitivity. Nanoparticles have enabled significant advances in pre-clinical cancer research as drug delivery vectors. Inorganic nanoparticles such as CdO/GrO nanoparticles have novel optical properties that can be used to optimize the signal-to-background ratio. This paper rep...

We present a multimodal optical microscope that incorporates six imaging modalities on one common platform. The imaging modalities include three staring modes, optical quadrature microscopy (OQM), differential interference contrast (DIC) microscopy, and epi-fluorescence microscopy, and three scanning modes, confocal reflectance microscopy (CRM), confocal fluorescence microscopy (CFM), and two-p...

The basics of four-wave mixing (FWM) and recent advances in FWM microscopy are reviewed with a particular emphasis on applications in the field of nanomaterials. The vast progress in nanostructure synthesis has triggered a need for advanced analytical tools suitable to interrogate nanostructures one at a time. The single-nanostructure sensitivity of optical microscopy has solidified the optical...

In this tutorial review in the thematic series "Acoustofluidics", we discuss the implementation and practice of optical microscopy in acoustofluidic micro-devices. Examples are given from imaging of acoustophoretic manipulation of particles and cells in microfluidic channels, but most of the discussion is applicable to imaging in any lab-on-a-chip device. The discussion includes basic principle...
