“…1 for two-photon resonance FWM), the FWM signal can be significantly enhanced. Because the FWM signal from nanomaterials can be electronically enhanced by several orders of magnitude, it allows visualization of single nanostructures, such as gold NRs [51], gold nanowires (NWs) [52, 53], and single-walled carbon nanotubes [54] (for a review, see [11]).…”

“…Therefore, fs lasers are preferred over ps ones for optimizing the efficiency of the electronic-resonance-enhanced FWM process, as has been demonstrated by Jung et al [51] and discussed in the recent review by Wang et al [11]. A single-beam near-degenerate FWM microscopy has been demonstrated by Min et al [101] and applied to ultrasensitive detection of chromophores and hemoglobin.…”

“…In contrast, electronic-resonance-enhanced FWM signals from various gold nanostructures including coupled gold nanoparticles [196], gold NRs [51], and gold NWs [53] have shown narrow spectral profiles at well defined frequencies. In the study of gold NR, Jung et al found that FWM signal was enhanced not only by surface plasmon resonance, but also by aggregation of NRs [51]. In another study by Kim et al , gold zigzag NWs exhibited a strong polarization-dependent FWM signal [53].…”

Because each nonlinear optical (NLO) imaging modality is sensitive to specific molecules or structures, multimodal NLO imaging capitalizes the potential of NLO microscopy for studies of complex biological tissues. The coupling of multiphoton fluorescence, second harmonic generation, and coherent anti-Stokes Raman scattering (CARS) has allowed investigation of a broad range of biological questions concerning lipid metabolism, cancer development, cardiovascular disease, and skin biology. Moreover, recent research shows the great potential of using CARS microscope as a platform to develop more advanced NLO modalities such as electronic-resonance-enhanced four-wave mixing, stimulated Raman scattering, and pump-probe microscopy. This article reviews the various approaches developed for realization of multimodal NLO imaging as well as developments of new NLO modalities on a CARS microscope. Applications to various aspects of biological and biomedical research are discussed.

“…Nonetheless, there are numerous problems in nanoscience in which the visualization of isolated nanostructures at their natural length scales can be useful. For instance, CARS excitation schemes have been used to detect the nonlinear response of plasmonic nanostructures [35,36]. A higher resolution would be highly desirable for mapping out the spatial distribution of the surface plasmon polarizability on individual nanostructures.…”

Rigorous calculations are performed to study the effective reduction of the nonlinear excitation volumes when using phase-only masks to condition the pump and Stokes driving fields. Focal volume reduction was achieved using both a multiplicative operation of the excitation fields as well as a subtractive operation. Using a tunable optical bottle beam for the Stokes field, an effective reduction of the width of the excitation volume by a factor of 1.5 can be achieved in the focal plane. Further reduction of the focal volume introduces a rapid growth of sidelobes, which renders such volumes unsuitable for imaging applications. In addition, phase sensitive detection was found to provide information from selective sub-divisions of the engineered coherent anti-Stokes Raman scattering excitation volume. In the case of isolated nanoparticles, an apparent resolution improvement by a factor of 3 is demonstrated, and it is shown that the size of sub-diffraction-limited particles can be accurately determined using phase sensitive detection.

“…Furthermore, the variability in the intensity values can be attributed to the aspect ratio and orientation of the bicelles as similar to such behaviours was previously observed in Au nanorods. 13 Figure 3 shows iso-intensity contours of particle #9 obtained from discrete intensity values at diffraction-limited resolution of 51 nm using a MATLAB code. The SPR modes of Au enable to image nanoscaled structures with a sharp contrast creating a "hot spot."…”

Experimental platform that allows precise spatial positioning of biomolecules with an exquisite control at nanometer length scales is a valuable tool to study the molecular mechanisms of membrane bound signaling. Using micromachined thin film gold (Au) in layered architecture, it is possible to add both optical and biochemical functionalities in in vitro. Towards this goal, here, I show that docking of complementary DNA tethered giant phospholiposomes on Au surface can create membrane-restricted nanodomains. These nanodomains are critical features to dissect molecular choreography of membrane signaling complexes. The excited surface plasmon resonance modes of Au allow label-free imaging at diffraction-limited resolution of stably docked DNA tethered phospholiposomes, and lipid-detergent bicelle structures. Such multifunctional building block enables realizing rigorously controlled in vitro set-up to model membrane anchored biological signaling, besides serving as an optical tool for nanoscale imaging.
