Abstract:
An atomic force microscope (AFM) has been used to measure the modulated photothermal displacement of a surface, thus acting as a local detector. This was demonstrated with Fourier transform infrared (FT-IR) and filter spectrometers focused on various samples. Similarly, surface layers were removed by an AFM and analyzed by the photothermal deformation of the coated cantilever. This work shows that the AFM can function as both an infrared detector and a precise surface separation device for spectroscopic analysis. The AFM combined with an FT-IR has the potential to enhance the sensitivity, selectivity, and spatial resolution of infrared spectroscopy.

Abstract:
A medium resolution mid-infrared FT-IR instrument (IBM Instruments IR 44) has been modified to do step scanning; this has been done with the use of concepts previously applied to both near- and far-infrared instruments. In this paper we illustrate the method used for driving the mirror in the step scan mode and present some preliminary results from using the instrument with photothermal detection. At the current state of development, results obtained with the use of phase modulation indicate that this method produces significantly higher signal-to-noise ratios than does the use of amplitude (chopper) modulation to generate the photothermal signal.

Abstract:
Frequency-domain laser infrared photothermal radiometry (PTR) and photoacoustic Fourier transform spectroscopy (FT-IR/PAS) were used for the measurement of the thermophysical properties (thermal diffusivity, α, and conductivity, k) of specialty paper samples with various cotton contents. An improved one-dimensional photothermal model of a free-standing sheet of paper in air that includes both the transmission and backscattering mode was introduced. A high degree of accuracy and reliability was obtained when a multiparameter-fit optimization algorithm was used to examine the transmission and backscattered PTR experimental results. The ability to measure α and its variation, Δα, as a result of the manufacturing process via the PTR technique is invaluable in terms of the quality control of paper products.

Abstract:
Vibrational spectroscopic imaging has become an emerging platform for chemical visualization of biomolecules and materials in complex systems. For over a century, both Raman and infrared spectroscopy have demonstrated the capability to recognize molecules of interest by harnessing the characteristic features from molecular fingerprints. With the recent development of hyperspectral vibrational spectroscopy imaging, which records the chemical information without sacrificing the spatial-temporal resolution, numerous discoveries has been achieved in the field of molecular and cellular biology. Despite the ability to provide complimentary chemical information to Raman-based approaches, infrared spectroscopy has not been extensively applied in routine studies due to several fundamental limitations: 1). the poor spatial resolution; 2). inevitable strong water absorption; 3). lack of depth resolution.
Mid-infrared photothermal (MIP) microscopy overcame all the above mentioned problems and for the first time, enabled depth-resolved in vivo infrared imaging of live cells, microorganisms with submicrometer spatial resolution. The development of epi-detected MIP microscopy further extends its application in pharmaceutical and materials sciences. With the deployment of difference frequency generation and other nonlinear optical techniques, the spectral coverage of the MIP microscopy was significantly enhanced to enable chemical differentiation in complex systems across the broad mid-infrared region. In addition to the efforts to directly improve the performance of MIP microscopy, a novel quantitative phase imaging approach based on polarization wavefront shaping via custom-designed micro-retarder arrays was developed to take advantage of the highly sensitive phase measurement in combination with the photothermal effect. Besides, the extended depth-of-field and multifocus imaging enabled by polarization wavefront shaping could both improve the performance of MIP microscopy for volumetric imaging.

This article considers the use of microspectroscopy for discriminating nanomolecular cellular alterations in biomedical research. It begins with an overview of some existing mid-infrared microspectroscopy techniques, including FTIR microspectroscopy and Raman microspectroscopy. It then discusses near-field techniques such as scanning near-field optical microscopy, near-field Raman microscopy, and photothermal microspectroscopy (PTMS). It also examines promising alternative sources of IR light, possible advantages of using normal atomic force microscopy probes, experimental procedures for PTMS, and prospects for high spatial resolution in near-field FTIR spectroscopy. Finally, it describes the spectroscopic detection of small particles, along with the use of the analysis paradigm to discriminate nanomolecular cellular alterations in biomedical research.

Abstract:
Abstract Failure analysis of organics at the microscopic scale is an increasingly important requirement, with traditional analytical tools such as FTIR and Raman microscopy, having significant limitations in either spatial resolution or data quality. We introduce here a new method of obtaining Infrared microspectroscopic information, at the submicron level in reflection (far-field) mode, called Optical-Photothermal Infrared (O-PTIR) spectroscopy, that can also generate simultaneous Raman spectra, from the same spot, at the same time and with the same spatial resolution. This novel combination of these two correlative techniques can be considered to be complimentary and confirmatory, in which the IR confirms the Raman result and vice-versa, to yield more accurate and therefore more confident organic unknowns analysis.

Abstract:
Abstract This paper discusses the use of optical photothermal infrared (O-PTIR) spectroscopy combined with Raman analysis. The new technique overcomes many of the limitations of conventional FTIR and Raman spectroscopy when used alone. It is based on an infrared-visible pump-probe system that incorporates a wavelength-tunable IR laser that emits a pulsed beam that is combined colinearly with the output of a 532-nm green laser. As the paper explains, infrared radiation is partially absorbed by the test target when the wavelength of the laser resonates with the vibrational mode of the material. This excitation process causes the area under the infrared spot to heat up, in turn, causing local expansion along with changes in the refractive indices. These photothermal effects cycle on and off in synch with the pulsed IR beam and the amplitudes of the on-off states are captured by the co-located visible beam and plotted as a function of wavelength over the tunable range of the IR laser. The diffraction limited spot size of the visible beam is approximately 416 nm, corresponding to a spatial resolution of about 1 μm, which is 30 times more precise than conventional FTIR. In addition, by measuring photothermal effects in localized regions, it is possible to identify chemicals in quantities of matter as small as 0.4 pg. By comparison, the sensitivity of transmission mode FTIR is significantly less at around 100 pg.

Abstract:
Abstract High resolution scanning probe microscopy techniques combined with infrared (IR) light sources offer unique solutions to combined chemical/mechanical/electrical characterization of defects in nanoscale dimensions. Previously, atomic force microscopy combined with infrared (AFM-IR) technology has demonstrated its capability to characterize nano-patterned metal/low-k dielectrics, nanoscale organic contaminants, and directed self-assembly of block co-polymers used for advanced micro/nanofabrications. In this paper, two complementary nanoscale chemical analysis techniques, photothermal AFM-IR and scattering type scanning near-field optical microscopy, are implemented to isolate and characterize microelectronic device cross-sections. It is observed that both techniques are able to detect patterned features with a half-pitch less than 15 nm.

Abstract Rapid identification of organic contamination in the semi and semi related industry is a major concern for research and manufacturing. Organic contamination can affect a system or subsystem’s performance and cause premature failure of the product. As an example, in February 2019 the Taiwan Semiconductor Manufacturing Company (TMSC), a major semiconductor manufacturer, reported that a photoresist it used included a specific element which was abnormally treated, creating a foreign polymer in the photoresist resulting in an estimated loss of $550M [1].
