“…Among these technologies, surface-enhanced Raman spectroscopy (SERS) has been identified as an impressive technique for recognizing environmental and biological traces of harmful substances, with superiorities such as prompt response, high sensitivity, and fingerprint characterization. , Silicon wafers and glass are the major substrates traditionally used in SERS . Nano-fabricated materials have been accurately prepared using ion beams, e-beam lithography, laser processing, and other methods to overcome the limitations associated with traditional SERS substrates. However, because of the high complexity of these substrate preparation techniques, the cost of large-scale production is too high.…”

In recent years, growing food safety and quality concerns have emerged and created an urgent need for the development of rapid and reliable food control technologies. This study proposes a novel surface-enhanced Raman spectroscopy (SERS) substrate printing technology that utilizes commercial filter paper functionalized by silver nanoparticles. We modified the Automatic TLC Sampler using a two-dimensional (2D) printer. The modification allows for various sampling modes which can be applied to 2D printing. The shape and size of nano silver on the substrate were determined, and the substrate sensitivity, uniformity, and stability were evaluated. As demonstrated by the experimental outcomes, the proposed technology is highly sensitive and reproducible, that is, the limit of quantitation was 10 −5 mg/kg, and the spot-to-spot and block-to-block Raman intensity variations were below 4.2%. We also successfully applied the technology to pears and apples for thiram recognition, yielding outstanding detectability down to 2.5 × 10 −6 and 3.9 × 10 −7 mg/mL (equal to 2.5 × 10 −3 and 3.9 × 10 −4 mg/kg), respectively. These were well below the maximum residue limit (7 mg/kg). More importantly, the linear relationships between thiram levels and the SERS intensity allow for sensitive monitoring of minute variations in agricultural insecticide residues. This proposed detection method can realize in situ detection with a strong signal fingerprint.

A fabrication technique is proposed based on tip-based ultrasonic vibration-assisted scratching (UVAS) combined with wet chemical etching. UVAS induced a deeper subsurface damage of the machined nanostructure than the conventional scratching (CS), obtaining a high depth-to-width ratio nanostructure after hydrofluoric acid etching. Furthermore, the tip wear for UVAS was lesser than that for CS owing to the small friction of UVAS. Furthermore, periodic nanograting structures, nanodot arrays, and chiral nanostructures were machined by controlling the UVAS trajectory. Moreover, surface-enhanced Raman scattering (SERS) substrates with nanodot arrays and chiral structures were prepared based on the transferred polydimethylsiloxane (PDMS) model after Au deposition. It was found that a large depth-to-width ratio SERS substrate contributed to a high enhancement of the Raman signal. A maximum enhancement factor of 4.03 × 105 could be obtained on an optimal nanodot array SERS substrate when measuring 10–5 mol/L rhodamine 6G (R6G). The circular dichroism (CD) spectra of the chiral nanostructures were revealed through the finite element method simulation. Moreover, the multipole resonance led to the CD enhancement of the chiral nanostructures. Furthermore, the chiral enantiomers (l- and d-cysteines) were tested with the SERS-active chiral nanostructures, which can be recognized using the chiral SERS substrates directly. Thus, the proposed method showed great potential in chiral applications such as chiral sensing and label-free detection.

In this study, a CBN liquid-body-armor-like grinding wheel was developed for high-shear and low-pressure (HSLP) grinding of Inconel718 alloy. The material removal mechanism of the novel CBN liquid-body-armor-like wheel was introduced in detail. Particle clustering effect of the new wheel was studied via the finite element method. A series of grinding tests were carried out to investigate the grinding performance under the various conditions. It was shown that the surface roughness Ra of the ground workpiece decreased from initial 0.3 to 0.094 μm. Simultaneously, the specific material removal rate of 1.069 × 105 μm3/mm·s was attained. The power spectral density function (PSDF) was employed to reveal the percentage of waviness and roughness of the surface profile, which was mainly concentrated in 0–40k Hz as compared with 60–120k Hz before grinding. It indicated that particle clustering effect was generated in the grinding zone. Besides, the maximum peak amplitude of the cross-correlation function coefficient of the ground workpiece surfaces before and after grinding was less than 0.3. The original scratches were completely removed. New and smooth textures generated after grinding. The experimental results demonstrated that the newly developed CBN liquid-body-armor-like grinding wheel was effective for surface finishing of the Inconel718 workpiece.
