“…Fungal and yeast biofilms are a serious medical concern because they confer resistance to biotic and abiotic stress conditions in the microorganism [58], particularly due to their ability to resist common antibiotics [59]. However, promising research has explored the use of laser-based techniques, such as optical ablation and antimicrobial photodynamic inactivation, as potential treatments for biofilms [60]. The effectiveness of laser irradiation in suppressing the growth of the fungus has been reported in labeling antibacterial quantum dots, with complete ablation achieved at laser irradiance [53].…”

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.

“…Selenium is a widely known semiconductor with excellent optoelectronic properties and is widely used in photosensitive devices [1][2][3], photocells [4], and other applications. There are six known isomers, with gray t-Se being the most stable due to the formation of a selenium chain similar to the double helix structure of DNA, where each selenium atom shares two electrons with other selenium atoms.…”

Over the past few decades, single-element semiconductors have received a great deal of attention due to their unique light-sensitive and heat-sensitive properties, which are of great application and research significance. As one promising material, selenium, being a typical semiconductor, has attracted significant attention from researchers due to its unique properties including high optical conductivity, anisotropic, thermal conductivity, and so on. To promote the application of selenium nanomaterials in various fields, numerous studies over the past few decades have successfully synthesized selenium nanomaterials in various morphologies using a wide range of physical and chemical methods. In this paper, we review and summarise the different methods of synthesis of various morphologies of selenium nanomaterials and discuss the applications of different nanostructures of selenium nanomaterials in optoelectronic devices, chemical sensors, and biomedical applications. Finally, we discuss possible challenges for selenium nanodevices and provide an outlook on the future applications of selenium nanomaterials.

“…Indeed, the main advantage of PLAL over other techniques is the surface's purity of nanoparticles being produced by relying on electrostatic repulsion, instead of steric repulsion like wet-chemistry does. PLAL uses a pulsed high-energy laser beam that is focused on a solid target material totally submerged into a liquid solvent [18][19][20]. When the laser pulse strikes the target, it creates a plasma plume containing the ionized species from the target and solvent [21,22].…”

Pulsed laser ablation in liquids (PLAL) is a colloidal synthesis technique attracting significant interest from the scientific community due to the quality of the nanoparticles being produced. In this type of synthesis protocol, the cavitation bubble plays a vital role during the synthesis of nanoparticles. This work studied the effect of the laser beam power on cavitation bubble lifetime. Three different laser beam power values (5.8 W, 7.5 W and 10.5 W) were used to irradiate a pure nickel target in de-ionized (DI) water to synthesize nickel-based nanoparticles. The optimal repetition rate maximizing the production of nanoparticles was determined by atomic emission spectroscopy for each laser beam power. It was determined that the optimal repetition rate increased exponentially with laser beam power, while the cavitation bubble lifetime decreased logarithmically with the laser beam power. Moreover, the effect of the laser beam power on the cavitation bubble lifetime also had an effect on the size distribution of the nanoparticles being produced; the smallest size distribution was obtained at the highest laser beam power.
