Laser Surface Texturing for Biomedical Applications: A Review

Abstract

For generating a texture or pattern on a work surface, one of the emerging processes is laser surface texturing (LST). It is an effective method for producing texture on a work surface. Literature shows that various lasers have been applied to generate textures on the surface of work materials. Recently, LST has shown tremendous potential in the field of biomedical applications. Applying the LST process, the efficacy of the biomaterial has been drastically improved. This paper presents an in-depth review of laser surface texturing for biomedical applications. The effect of LST on important biomaterial has been thoroughly studied; it was found that LST has extreme potential for surface modification of biomaterial and can be utilized for biomedical applications.

Laser Processing of Polymer Films Fabricated from PHAs Differing in Their Monomer Composition

“…One of the new processes of adding texture or picture onto the effective surface of polymer products is laser surface texturing (LST) [59]. A number of studies showed the high potential of LST for modifying and enhancing the effectiveness of biomedical materials.…”

“…Shivakoti et al [59] presented an in-depth review of laser surface texturing for biomedical applications. The researchers used various types of lasers, such as CO 2 laser, excimer laser, fiber laser, etc., to produce texture to explore the efficacy of the process and its impact on proliferation, osseointegration, cell adhesion, etc.…”

“…Analysis of the most recent published studies, including a thorough review by Professor Ravi-Kumar et al [58], key experimental works [28,48,54,55], and the latest studies [56][57][58][59]61,62] has provided the basis for summarizing the currently available data and existing notions of the effects produced by laser treatment of polymer materials. Laser ablation is widely used today to treat various materials (metals, ceramics, glass, and polymers).…”

The Effect of Beam Direction on Absorption and Transmission of Ultraviolet to Infra-red Wave-length in Three Different Dentin Thicknesses

“…The domain of these effects is important from diagnostic, clinical, and cosmetic aspects as the adaptation of color plays a key role [1][2][3]. Additionally, the effects of the laser light on mechanisms associated with cavity preparation and treating the surface of dentin [4,5] as well as the process of disinfection [6], and different dimensions of tissue regeneration are well evident [7, 8].…”
