“…Another published work about melting the material precisely in the regions of plasmonic hotspots also proves the effect of surface plasmon on laser ablation [17]. Moreover, a near-field laser ablation system was developed for the analysis of inorganic solid samples with a nanometer resolution [18]. With the assistance of plasmonic resonant of Au bowtie nano antennas, an ablation mechanism called gentle ablation (electrostatic ablation) since its ablation rate is several orders of magnitude lower than that of thermal ablation, was observed on SiO 2 [19][20][21].…”

Colloidal Au nanoparticles (NPs) were decorated on stainless steel for surface plasmon enhanced laser ablation. A comparative study of the laser ablation efficiency was carried out on stainless steel samples with and without the Au NPs decoration at a variable pulsed laser fluence and laser pulse number. Higher ablation efficiency was clearly demonstrated in the former as illustrated from the larger diameter, maximum depth and the cross-sectional area of the crater generated by the laser ablation under the same conditions. Additionally, both the maximum depth and efficiency enhancement were found to depend on the laser fluence and pulse number. The maximum enhanced ablation efficiency of 36% based on the cross-sectional area of the crater was obtained at 1 pulse number of laser fluence 1.53 J cm −2 . The efficiency enhancement of laser ablation is attributed to the highly enhanced surface plasmon field at the interface between Au NPs and stainless steel.

The wavelength dependence of atomic force microscope apertureless tip-enhanced laser ablation was studied using a series of organic dyes to assess the effect of surface optical absorption. An optical parametric oscillator laser with a tunable wavelength range of 410−2100 nm was used to irradiate a gold-coated atomic force microscope tip which was held 15 nm above the surface of a dye thin film vibrating in tapping mode to generate tip-enhanced laser ablation. Crater formation was investigated for rhodamine B, methylene blue, and IR 797 dye thin films which have absorption maxima near 550, 650, and 700 nm, respectively. Crater formation was not observed for wavelengths greater than 700 nm for any of the dyes. Below 700 nm, the crater size was greatest near 500 nm for all dyes and decreased from 500 to 700 nm, and no ablation was observed at longer wavelengths. The crater size did not correlate with the solution or thin film optical absorption of the dyes. The mechanism for tip-enhanced laser ablation is postulated to be either ballistic ejection of gold atoms or direct heat transfer from the tip to the surface.

Mass spectrometry imaging (MSI) technologies are widely used today to study the in situ spatial distributions for a variety of analytes. As these technologies advance, the pursuit of higher resolution in MSI has intensified. The limitation of direct desorption/ionization is its insufficient ionization, posing a constraint on the advancement of high‐resolution MSI technologies. The introduction of postionization process compensates the low ionization efficiency caused by sacrificing the desorption area while pursuing high spatial resolution, resolving the conflict between high spatial resolution and high sensitivity in direct desorption/ionization method. Here, we discuss the sampling and ionization steps of MSI separately, and review the postionization methods in MSI according to three different sampling modes: laser sampling, probe sampling, and ion beam sampling. Postionization technology excels in enhancing ionization efficiency, boosting sensitivity, mitigating discrimination effect, simplifying sample preparation, and expanding the scope of applicability. These advantages position postionization technology as a promising tool for biomedical sciences, materials sciences, forensic analysis and other fields.
