“…[1,2,3,4,5], which meant that it was a good candidate for the absorption or detection of small moelcules [6,7]. Since 2008, a variety of graphene nanocomposites with different morphologies, for example, nanosheets [8], nanobelts [9], quantum dots [10], nanofibers [11], and three-dimensional topographies [12], etc., have been reported.…”

Husk derived amino modified linear graphene nanocomposites (aLGN) with a diameter range of 80–300 nm and a length range of 100–300 μm were prepared by a modified Hummers method, ammonia treatment, NaBH4 reduction and phenylalanine induced assembly processes, etc. The resulting composites were characterized by transmission electron microscopy (TEM), atomic force microscopy (AFM), scanning electron microscopy (SEM), biological microscope (BM), and X-ray diffraction spectroscopy (XRD), etc. Investigations found that the aLGN can serve as the novel coating of stir bar sorptive extraction (SBSE) technology. By combing this technology with gas chromatography–mass spectrometry (GC-MS), the combined SBSE/GC-MS technology with an aLGN coating can detect seventeen kinds of amino acids of Camellia nitidissima Chi seeds, including Ala, Gly, Thr, Ser, Val, Leu, Ile, Cys, Pro, Met, Asp, Phe, Glu, Lys, Tyr, His, and Arg. Compared to a conventional polydimethylsiloxane (PDMS) coating, an aLGN coating for SBSE exhibited a better thermal desorption performance, better analytes fragmentation depressing efficiencies, higher peak intensities, and superior amino acid discrimination, leading to a practicable and highly distinguishable method for the variable amino acid detection of Camellia nitidissima Chi seeds.

“…Optoelectronic nanoscopy has been demonstrated to detect plasmons electrically. In 2016, Lundeberg et al detected the propagating graphene plasmons electrically for the first time. Graphene also acts as a thermoelectric detector by transferring electronic heat into a voltage signal, where a graphene sheet was clipped in h‐BN and two separated local gates were fabricated directly underneath the hBN.…”

Polaritons in 2D materials exhibit extensive optical phenomena, such as an ultrahigh field confinement and tunability and, thus, have been attracting increasing attentions. Many different methods have been developed to characterize and manipulate polaritons, which in turn has promoted a steady booming of this field. Here, the significant progress made in probing polaritons in 2D materials based on the characterization method, i.e., optical far‐field, optical near‐field, and (opto)electronic methods is reviewed. Perspectives on the potential development and applications of these methods are also discussed.

“…At the end of this section, we remark that, in addition to detecting polariton standing waves from scattering field off the s‐SNOM tip, the s‐SNOM setup can be implemented with photocurrent, photoinduced force or peak force setup, as photon‐free imaging schemes for polariton waves.…”

Phonon polaritons provide useful opportunities, complementary to those provided by plasmon polaritons, in the study of the interaction of light with matter at small scales. The focus of this review is on phonon polaritons in low‐dimensional van der Waals (vdW) materials and heterostructures. Phonon polaritons confined in vdW materials exhibit large electromagnetic localization and are easy to hybridize with other collective modes. The extreme optical anisotropy in vdW systems produces the natural hyperbolic dispersion, enabling the access to deep subdiffractional optics and often yielding improved figures of merit over hyperbolic metamaterials. These virtues hold promises for practical nanophotonic applications, including optical sensing, super‐resolution imaging, energy and emission engineering, quantum optics, and a next generation of optical circuit elements.
