“…The surface roughness by itself could also affect the hydrophilicity of the surface. Ahad and collaborators [18] studied the surface modification of PET films by irradiation with extreme ultraviolet photons to further evaluate the effects on the surface structure and wettability. Results showed that the water contact angle increased with an increased surface roughness.…”

Polyethylene terephthalate (PET) is one of the most used polymeric materials in the health care sector mainly due to its advantages that include biocompatibility, high uniformity, mechanical strength and resistance against chemicals and/or abrasion. However, avoiding bacterial contamination on PET is still an unsolved challenge and two main strategies are being explored to overcome this drawback: the anti-adhesive and biocidal modification of PET surface. While bacterial adhesion depends on several surface properties namely surface charge and energy, hydrophilicity and surface roughness, a biocidal effect can be obtained by antimicrobial compounds attached to the surface to inhibit the growth of bacteria (bacteriostatic) or kill bacteria (bactericidal). Therefore, it is well known that granting antibacterial properties to PET surface would be beneficial in the prevention of infectious diseases. Different modification methods have been reported for such purpose. This review addresses some of the strategies that have been attempted to prevent or reduce the bacterial contamination on PET surfaces, including functionalisation, grafting, topographical surface modification and coating. Those strategies, particularly the grafting method seems to be very promising for healthcare applications to prevent infectious diseases and the emergence of bacteria resistance.

“…The polymer samples were irradiated with 50 or 300 EUV shots at 10 Hz repetition rate in the presence of EUV-ionized nitrogen gas in the interaction region [12]. The detailed arrangement and working of the source on PTFE and other polymers for application in biomedical engineering are documented before [11,13]. Cells grown on samples for 24, 48, 72, and 96 h and prepared for fluorescent microscopy according to procedures described elsewhere [14].…”

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.

“…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.
