“…We compared our error bar by considering the evolution of the sample under irradiation. It is worth mentioning that quantitative data with a statistical approach should be considered to better describe the contribution of laser irradiation to the experimental data [11]. The intensity of light per unit area, or optical irradiance, is a key factor in numerous biological reactions.…”

“…It has been demonstrated that phototherapy [8] and antimicrobial photodynamic therapy [9] are an effective strategy against C. albicans infection. Moreover, the assistance of optical nonlinearities promoted by femtosecond lasers seems to promise positive results; however, it is necessary to optimize the parameters of irradiation to improve the elimination of bacteria [10] and improve the quality of the photoinduced effects [11].…”

This work reports the modification in the homogeneity of ablation effects with the assistance of nonlinear optical phenomena exhibited by C. albicans ATCC 10231, forming a biofilm. Equivalent optical energies with different levels of intensity were irradiated in comparative samples, and significant changes were observed. Nanosecond pulses provided by an Nd:YAG laser system at a 532 nm wavelength in a single-beam experiment were employed to explore the photodamage and the nonlinear optical transmittance. A nonlinear optical absorption coefficient −2 × 10−6 cm/W was measured in the samples studied. It is reported that multiphotonic interactions can promote more symmetric optical damage derived by faster changes in the evolution of fractional photoenergy transference. The electrochemical response of the sample was studied to further investigate the electronic dynamics dependent on electrical frequency, and an electro-capacitive behavior in the sample was identified. Fractional differential calculations were proposed to describe the thermal transport induced by nanosecond pulses in the fungi media. These results highlight the nonlinear optical effects to be considered as a base for developing photothermally activated phototechnology and high-precision photodamage in biological systems.

“…Hence, it is stipulated that the mercury was absorbed and accumulated in the root of fern, proving its ability as biosorbent for mercury. Not only as biosorbent, the enrichment of heavy metal in a solid sample such as the root is beneficial for contamination the monitoring techniques using laser spectroscopy [Iqhrammullah et al, 2021;Nisah et al, 2022]. As suggested previously, plants act as direct receivers of heavy metal contaminant through water absorption [Pal & Sukul, 2022].…”

“…Moreover, several studies have shown the use of ISE on the determination of total fluorine on different matrices, such as foams, fuels, lubricants, and organic materials [ 12 , 13 , 14 ]. Additionally, the successful fabrication of ISE from a polyurethane membrane for lead analysis was reported in several research studies [ 15 , 16 , 17 ]. An overview of common analytical techniques for the evaluation of TF/TOF and PFAS [ 18 ] is described in Table 1 .…”

Various testing methods and techniques have been used to identify and quantify per- and polyfluoroalkyl substances (PFAS) in food packaging. A common indirect measurement of PFAS is total fluorine (TF) and total organic fluorine (TOF). These methods are critical in rapidly screening food packaging materials for the >9000 PFAS and are often globally used for regulatory limits. However, this destructive approach requires careful sample preparation, combustion, and the analysis of the solution by a fluoride-specific electrode. The method described herein is a cost-effective, rapid, quantitative, and externally validated initial screening of packaging materials for fluoro-chemistry. This study presents validated protocols for measuring TF and TOF in packaging substrates using oxygen combustion sample preparation coupled with fluoride ion-selective electrode (F-ISE); the materials and required equipment are provided, and the step-by-step procedure from sample preparation to the analysis are described, including critical steps to minimize contamination and interferences during sample preparation.
