Surface modification of bio‐carrier by plasma oxidation‐ferric ions coating technique to enhance bacterial adhesion

Abstract RB-SiC ceramic is one of the most important and useful material as optical precision elements in many scientific research fields. In this paper, a novel cold atmospheric plasma (CAP), which is based on the precision grinding process in surface technology to modify at room temperature (RT) for grinding with a combination of plasma oxidation surface modification is proposed. To identify the performance of the proposed cold atmospheric plasma (CAP) method on the surface modification of RB-SiC ceramic, precision grinding test was conducted. To reveal the fundamental issue in the grinding of RB-SiC ceramic, numerical calculation and model analysis were conducted to investigate the effect of the composite process on grinding forces and the mechanism of subsurface material removal in the presence of plasma oxidation. As a result of the method included the kept constant during the precision grinding of the composite process self-adaption-grinding process to avoid the deviation caused by second grinding particle entry. As a summary, we provides a significant cold atmospheric plasma-precision grinding compound process toward the establishment of the basic theory by analyzing the mechanism of the simulated design and computation. The process and technical difficulties of RB-SiC ceramic and mechanism of subsurface material removal during precision grinding were be solved.

ABSTRACTThe goal of this research was to investigate the ability of lubricin to prevent bio-fouling of intraocular lenses after surgery, through surface coating trials with lubricin and analogues of the two major sub-units of the lubricin molecule (mucin and vitronectin). Yearly, there are over 6 million surgeries worldwide that involve intraocular lenses (IOLs) 1. However, preventing post-operative biofouling and bacterial infection of these implants remains a challenge 2. Surface modification of IOLs may provide a solution. This study proposes the use of the anti-adhesive protein lubricin (LUB), a glycoprotein found in the synovial fluid, as a means to make polymer surfaces less prone to bacterial adhesion and proliferation; thus, reducing the opportunity for post-operative infection 3. This study used extended bacteria growth trials on tissue cultures polystyrene coated with either lubricin, vitronectin, or mucin to investigate how lubricin and protein sub-regions of lubricin may reduce bacterial adhesion and proliferation.
