Theory of mid-infrared absorption microspectroscopy: II. Heterogeneous samples.
Fourier transform infrared (FT-IR) spectroscopic imaging combines the specificity of optical microscopy with the spectral selectivity of vibrational spectroscopy. There is increasing recognition that the recorded data may be dependent on the optical configuration and sample morphology in addition to its local material spectral response, but a quantitative framework for predicting such dependenc...
متن کاملIn vitro colocalization of plasmonic nano-biolabels and biomolecules using plasmonic and Raman scattering microspectroscopy.
An insight into the intracellular fate of theranostics is important for improving their potential in biological applications. In vivo efficacy of plasmonic theranostics depends on our ability to monitor temporal changes in their size, shape, and state of aggregation, and the identification of molecules adsorbed on their surfaces. We develop a technique which combines plasmonic and Raman scatter...
متن کاملCollective behavior of impedance matched plasmonic nanocavities.
Nanometer sized cavities arranged as a subwavelength metallic grating can provide omni-directional and complete absorption of light. We present an explanation of this extraordinary phenomenon as a collective resonant response of a system based on a surface impedance model. This model gives a straightforward way to design systems for optimum light trapping performance and as well gives fundament...
متن کاملMid-infrared Microspectroscopy of Difficult Samples Using Near-Field Photothermal Microspectroscopy
www.spectroscopyonl ine.com espite recent advances in Fourier transform-infrared (FT-IR) microspectroscopy and micro-attenuated total reflectance (ATR), for many types of samples there remains a need for even higher spatial resolution, or for a nondestructive method of recording localized mid-IR spectra from asreceived samples without the risk of damage or alteration by preparation techniques. ...
متن کاملMultimode fibre based imaging for optically cleared samples
Optical clearing is emerging as a popular approach particularly for studies in neuroscience. However the use of corrosive clearing solutions typically requires sophisticated objectives or extreme care with optical components chosen for single- or multi-photon imaging. In contrast to the use of complex, custom-made microscope objectives, we show that the use of a corrected multimode fibre (MMF) ...
