Abstract
In recent years, the introduction of nanoparticles (NPs) in coating systems to impart antibacterial activity to substrates of interest is on the rise to counteract drug-resistant bacterial infections. In this regard, a coating system was developed using curcumin/Ag NPs (C-Ag NPs) complex in ethanolic suspension to be used as an antibacterial coating material for gutta-percha (dental filler) and cotton fabric. The prepared NPs were thoroughly characterized by employing x-ray diffraction, high-resolution scanning electron microscopy, Fourier Transform infrared spectroscopy, UV–vis spectroscopy, and particle size analysis. A simple dip coating technique with a solvent evaporation route was employed to modify the surfaces of gutta-percha and the cotton fabric. The antibacterial activity of C-Ag NPs modified gutta-percha and cotton fabric was assessed using a modified colony counting route and AATCC-147 standard, respectively, and displayed better results than curcumin-modified substrates. Therefore, the pathway for bacterial infections after root canal treatment and the spread of hospital-acquired infections in the hospital sector can be restricted with the use of C-Ag NPs modified gutta-percha and cotton fabric, respectively.
