“…It is known that laser fluence plays a critical role in laser-material interaction (Farha et al, 2012;Mahmood et al, 2009;Farha et al, 2012;Fornarini et al, 2006;Lippert et al, 1993). We previously found that laser fluence has a significant effect on thin film and nanoparticle properties, such as size, surface roughness, number of particles, and film density (Farha et al, 2012;Belekov et al, 2020;Kholikov et al, 2018;Hakimov et al, 2022).…”

The formation of laser-induced periodic surface structures (LIPSS) on mirror-polished 304-grade stainless steel sheets with dimensions 25 mm × 25 mm × 0.8 mm upon irradiation with picosecond laser pulses in air and water environments at different wavelengths, number of pulses, and laser energy densities was investigated. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) were used to characterize the LIPSS. Tunable periodicity of the LIPSS was observed in both media at different wavelengths and fluence. Fluence was shown to be the main formation parameter of LIPSS; however, the medium was also demonstrated to play an important role. Our results show that LIPSS can be successfully generated on stainless steel in a single-step process and that they can be easily modified by adjusting laser parameters.

“…Additionally, they have been found to inhibit the biofilm formation of PA [ 104 , 105 ]. Interestingly, silver nanoparticles have been combined with photosensitizer methylene blue to increase the antimicrobial effect of PDT [ 106 ]. As such, silver nanoparticles may provide synergistic interactions that could improve PDT and should be investigated in this field further.…”

As a prevalent medical problem that burdens millions of patients across the world, chronic wounds pose a challenge to the healthcare system. These wounds, often existing as a comorbidity, are vulnerable to infections. Consequently, infections hinder the healing process and complicate clinical management and treatment. While antibiotic drugs remain a popular treatment for infected chronic wounds, the recent rise of antibiotic-resistant strains has hastened the need for alternative treatments. Future impacts of chronic wounds are likely to increase with aging populations and growing obesity rates. With the need for more effective novel treatments, promising research into various wound therapies has seen an increased demand. This review summarizes photodynamic therapy, probiotics, acetic acid, and essential oil studies as developing antibiotic-free treatments for chronic wounds infected with Pseudomonas aeruginosa. Clinicians may find this review informative by gaining a better understanding of the state of current research into various antibiotic-free treatments. Furthermore. this review provides clinical significance, as clinicians may seek to implement photodynamic therapy, probiotics, acetic acid, or essential oils into their own practice.

“…Mechanistic studies demonstrated that most Ag NPs undergo intersystem crossing to the triplet state upon photoexcitation. Subsequent transitions to the triplet excited state significantly prolong the lifetime of the electrons, thereby enhancing the excitation ability of the oxygen molecules (Hakimov et al, 2022). Currently, Ag is primarily used as a carrier or enhancer in PDT.…”

Microbial infections continue to pose a significant health challenge, especially with an increase in drug-resistant bacteria. Conventional antibiotic treatments show limited efficacy, prompting researchers to explore alternative treatments. Photodynamic therapy (PDT) has emerged as a promising alternative that uses reactive oxygen species (ROS) to induce oxidative stress, offering the potential for cyclic treatment without fostering new drug resistance mechanisms. The success of PDT relies heavily on the selection of appropriate photosensitizers (PSs). Various nanomaterials are being developed as PSs or carriers to enhance the efficacy of PDT in the antibacterial field. In this comprehensive review, we discuss the four main ROS generated during PDT and outline their corresponding antibacterial mechanisms. Additionally, we highlight the prominent types of nanomaterials used as PSs or carriers in PDT. We analyze the current challenges associated with nanomaterial-based PDT for antibacterial therapy and propose potential strategies for optimizing their applications.
