“…It was demonstrated the ability of UV radiation to generate micropatterns, and chemical modifications on PC/PMMA blend surfaces. Regarding the chemical composition after UV laser irradiation, a more detailed study was performed by Ahad et al using a laser-plasma extreme ultraviolet (EUV) source [103]. XPS analysis revealed a decrease in the surface oxygen content after laser processing, which resulted in an increase of the hydrophobicity of the PC surface.…”

Polymers are materials widely used in biomedical science because of their biocompatibility, and good mechanical properties (which, in some cases, are similar to those of human tissues); however, these materials are, in general, chemically and biologically inert. Surface characteristics, such as topography (at the macro-, micro, and nano-scale), surface chemistry, surface energy, charge, or wettability are interrelated properties, and they cooperatively influence the biological performance of materials when used for biomedical applications. They regulate the biological response at the implant/tissue interface (e.g., influencing the cell adhesion, cell orientation, cell motility, etc.). Several surface processing techniques have been explored to modulate these properties for biomedical applications. Despite their potentials, these methods have limitations that prevent their applicability. In this regard, laser-based methods, in particular laser surface texturing (LST), can be an interesting alternative. Different works have showed the potentiality of this technique to control the surface properties of biomedical polymers and enhance their biological performance; however, more research is needed to obtain the desired biological response. This work provides a general overview of the basics and applications of LST for the surface modification of polymers currently used in the clinical practice (e.g., PEEK, UHMWPE, PP, etc.). The modification of roughness, wettability, and their impact on the biological response is addressed to offer new insights on the surface modification of biomedical polymers.

“…This method has some advantages, like low cost, high resolution, highoperating speed, and the fact that lasers do not change the bulk properties of implant and just treat a certain surface, which makes it an interesting method among other methods in polymer surface modification [30]. Considerable numbers of researches have been conducted regarding laser method for polymer modification and investigated the effect of the different laser device and laser parameters on the surface properties and cell adhesion, which is caused by the change of wettability and functional group of the surface [27,67,68]. Laser technique is one of the simplest techniques to modify both surface topography and chemistry.…”

“…The contamination of the process is easily avoided, offers high processing speed, easy automation, and the possibility to treat large areas by controlling the parameters of the laser process [18]. Therefore, laser technology has been used for surface modifications of materials, especially polymers like ultra-High-Molecular-Weight Polyethylene (UHMWPE) [19][20][21], polypropylene (PP) [22,23], Polyethylene (PE) [24,25], Polycarbonate (PC) [26,27], polytetrafluoroethylene (PTFE) [28], Polyimide (PI) [29] and PEEK, in some studies [30].…”

Polyether ether ketone (PEEK) is one the most interesting polymeric materials used in the industry today, such as aerospace, nuclear reactors, polymer electrolyte membranes and especially in biomedical applications like bone implants. PEEK’s desirable properties like mechanical strength, biocompatibility, chemical resistance, radiation resistance and high thermal stability in the body make this suitable polymer choice for a bone implant. Besides these useful properties, PEEK is bio-inert in the biological environment, which is a big problem in implant application. Fortunately, there are several methods to improve the surface bioactivity of such materials. Here surface modification methods of the PEEK, including laser and their effect on the surface bioactivity were studied. Laser techniques are one of the exciting methods for PEEK surface modification because of being a secure processing method, time-consuming, easy to control the laser parameter, which leads to the control of surface properties. Several kinds of laser with different settings is used for the enhancement of the surface of PEEK, were described here. Here different surface modification techniques to enhance the adhesion and wettability of the PEEK surface studied. Along with varying categories of laser were introduced and different laser methods, which used for PEEK surface treatment is collected, that is the exciting point of this review paper.

During the last two decades, the development of laboratory scale extreme ultraviolet sources has been intensified due to growing interest in use of extreme ultraviolet photons for various applications in science and technology. In this study, we present a potential application of extreme ultraviolet sources for surface modification of polymers to be used as substrates for cancer cell identification. The surface modification of polytetrafluoroethylene (PTFE) polymer samples was performed by a lab scale compact laser-plasma extreme ultraviolet source based on a double-stream gas-puff target. The gas target was irradiated with a 3 ns/0.8 J Nd:YAG laser pulse at 10 Hz. Reference HCV29 non-malignant transitional epithelium and T24 bladder cancer cells adhesion and proliferation studies on pure and extreme ultraviolet sources modified PTFE surfaces were performed. The extreme ultraviolet modified surfaces demonstrated regular increase in cancer cell proliferation comparing to pristine sample. Initial results indicate that extreme ultraviolet treated substrates can facilitate the identification of cancer cells.
