Studying the effect of MWCNTs/zirconia nano composite in reducing tumor cells

Abstract

The augmented popularity of all ceramic materials as an alternative to metal ceramic restorations attributed to their Excellent Aesthetics, Chemical Stability, and Biocompatibility. Recently, the expansion of advanced dental ceramics has led to the application of partially stabilized zirconia in restorative dentistry. In this study, we prepared zirconia matrix stabilized in the Tetragonal Phase by adding yttrium oxide (3% mol. Y2O3) with homogeneous distribution for different weight additions of (2%, 5%, 7%, 10%) wt of F-MWCNTs as reinforced to form (3% mol. Y2O3-ZrO2 / F-MWCNTs ) Nano composite materials using pressing uniaxially (624) MPa in the metal-die cylindrical to form pellets of (10 mm diameter), Then the pellets were sintering in air at (1550°C) for (2) hours. The results were characterized by using FTIR to determine the vibrational mode after treated MWCNTs. Besides, study the Cell viability of samples by MTT assay to investigate the activity of composite (3% mol. Y2O3- ZrO2) (10%) wt. F-MWCNTs in kill the tumor cells. The results improved best antibacterial activity of samples at concentration the 150µg.mL−1 of the ratio (7% - 10%) wt. of F-MWCNTs where three types of bacteria pathogen (E. coli, P. aeruginosa and S. aureus) which show the good antibacterial activity, also can see the good results of adhesion bacterial.The augmented popularity of all ceramic materials as an alternative to metal ceramic restorations attributed to their Excellent Aesthetics, Chemical Stability, and Biocompatibility.
