Chemical imaging (as quantitative – chemical mapping) is the analytical capability to create a visual image of components distribution from simultaneous measurement of spectra and spatial, time information.

In this chapter, chemical imaging is addressed in the context of an overarching goal to understand and control complex chemical processes. Understanding and controlling complex chemical processes requires the ability to perform multimodal imaging across all length and time scales.

Chemical imaging techniques provide invaluable insights into the chemical composition and distribution of materials. By combining microscopy and spectroscopy, these techniques enable researchers to visualize and map chemical species with high …

3 days ago · This drawback has driven the development of vibrational imaging techniques, which can identify molecules based on their unique chemical bonds without altering the sample. These methods detect physical changes in samples when they absorb mid-infrared (MIR) light, such as shifts in refractive index caused by heat absorption or temperature-induced ...

Chemical imaging is the analytical capability (as quantitative mapping) to create a visual image from the simultaneous measurement of spectra (as quantitative chemical), spatial, and time information.

2 days ago · In terms of resolution, SIMIP achieved a 1.5-fold improvement over conventional MIR photothermal imaging, with a full width at half-maximum (FWHM) of 335 nm versus 444 nm in standard methods.

Jan 1, 2015 · Chemical imaging methods reveal the chemical composition on a spatially resolved level over a range of length scales (millimetres to nanometres). They make use of a variety of excitation mechanisms and detection schemes such as: raster scanning, multichannel detection and parallel channel detection.

Dec 11, 2024 · Speakers and attendees have defined the mission of chemical imaging at two levels. The first is mapping of chemical distribution in cells, tissues, and functional materials. The second is imaging of molecular transformations in real time and space.

2 days ago · As super-resolution imaging continues to evolve, tools like SIMIP will undoubtedly play a central role in unraveling the intricacies of the nanoscale world, granting researchers the unprecedented ability to observe, analyze, and understand the chemical and structural dynamics of matter at an extraordinary level of detail.

Chemical imaging is the simultaneous measurement of spectra (chemical information) and images or pictures (spatial information). The technique has applications in chemistry, biology and medicine, and is most often applied to solid-state samples.
