“…Natali et al 118 used a similar approach to characterize the temperature-dependent loss tangent of PS, PE, polycarbonate (PC), and a polymer-based nanocomposite from 25 to 70 °C. PS, PE, and PC were used as calibration samples to validate the approach over the temperature range; the resulting tan δ values agreed with data from the literature both in terms of their absolute values and their trends with temperature.…”

Contact resonance force microscopy (CRFM) is an atomic force microscopy (AFM) method that evolved from a curiosity about the detection of ultrasonic vibrations with an AFM cantilever and an unaddressed need to characterize the mechanical properties of stiffer materials (elastic modulus >50 GPa). The method has matured to allow near-surface and subsurface elastic property measurements of single crystals, thin films, nanomaterials, composites, and other advanced materials. More recently, CRFM has been extended to viscoelastic property measurements, where the CR frequency and CR quality factor are utilized to quantitatively assess properties such as storage modulus, loss modulus, and loss tangent. In this Perspective, we trace the evolution of CRFM from initial discovery to elastic property measurements to viscoelastic property measurements. The techniques for extending single-point property measurements to two-dimensional property maps are then described in terms of their operational characteristics, demonstrated on calibration materials, and validated via comparisons to other viscoelastic measurement tools. The focus of the discussion then shifts to viscoelastic CRFM in nonambient conditions to highlight the challenges and developments related to thermomechanical analyses and liquid operation. The current state-of-the-art and best practices in data acquisition and analyses for viscoelastic CRFM are elucidated via a step-by-step demonstration on a wood–polymer composite. Finally, we conclude with a discussion of potential polymer science application areas that are poised to benefit from the recent advances in the ambient and nonambient CRFM methodologies. Altogether, we feel that the recent addition of CRFM to commercially available AFMs together with guides that clearly define state-of-the-art and best practices will accelerate its acceptance and adoption in polymer science via viscoelastic property measurements at unprecedented length and time scales.

“…For this purpose, we acquired the values of f 1 and f 2 and the corresponding quality factors Q 1 and Q 2 on both the Ti/PMMA and the commercial bulk PMMA. The values of tanδ were then calculated as detailed elsewhere [49].…”

“…Formerly referred to as atomic force acoustic microscopy (Rabe, Kopycinska‐Müller, & Hirsekorn, ) or ultrasonic AFM (Yamanaka & Tsuji, ), from the value of one or more CRFs, CR‐AFM allows one to quantitatively measure and map the indentation modulus of materials with elastic properties varying in a broad range, that is, from stiff crystals, ceramics (Rabe et al, ) and gemstones (Passeri et al, ), hard coatings like diamond‐like carbon (Amelio et al, ; Passeri et al, ) to soft materials like polymers (Liu et al, ) or biological samples (Ebert et al, ). Moreover, by analyzing both CRFs and their quality factors Q c , CR‐AFM enables the characterization of viscoelastic materials allowing the quantitative mapping of storage and loss moduli and loss tangent, as demonstrated on polymer blends (Chakraborty & Yablon, ; Hurley, Campbell, Killgore, Cox, & Ding, ; Killgore, Yablon, et al, ; Yablon et al, ; Yablon, Grabowski, & Chakraborty, ), polymer‐based nanocomposites reinforced with hard nanomaterials (Natali et al, ), and biological samples (Churnside, Tung, & Killgore, ). The broadness of the range of materials which can be studied makes CR‐AFM a fairly versatile technique for subsurface imaging.…”

Identification of nanoparticles and nanosystems into cells and biological matrices is a hot research topic in nanobiotechnologies. Because of their capability to map physical properties (mechanical, electric, magnetic, chemical, or optical), several scanning probe microscopy based techniques have been proposed for the subsurface detection of nanomaterials in biological systems. In particular, atomic force microscopy (AFM) can be used to reveal stiff nanoparticles in cells and other soft biomaterials by probing the sample mechanical properties through the acquisition of local indentation curves or through the combination of ultrasound-based methods, like contact resonance AFM (CR-AFM) or scanning near field ultrasound holography. Magnetic force microscopy can detect magnetic nanoparticles and other magnetic (bio)materials in nonmagnetic biological samples, while electric force microscopy, conductive AFM, and Kelvin probe force microscopy can reveal buried nanomaterials on the basis of the differences between their electric properties and those of the surrounding matrices. Finally, scanning near field optical microscopy and tip-enhanced Raman spectroscopy can visualize buried nanostructures on the basis of their optical and chemical properties. Despite at a still early stage, these methods are promising for detection of nanomaterials in biological systems as they could be truly noninvasive, would not require destructive and time-consuming specific sample preparation, could be performed in vitro, on alive samples and in water or physiological environment, and by continuously imaging the same sample could be used to dynamically monitor the diffusion paths and interaction mechanisms of nanomaterials into cells and biological systems. This article is categorized under: Diagnostic Tools > In Vivo Nanodiagnostics and Imaging Nanotechnology Approaches to Biology > Nanoscale Systems in Biology.
