Functionalization of AgCl/Titania Nanocomposite with Folic Acid: A Promising Strategy for Enhancement of Antimicrobial Activity

Anti-quorum sensing activity of AgCl-TiO2 nanoparticles with potential use as active food packaging material

“…The anti‐QS activity of ATNPs in this study has been achieved at a much lower concentration of silver (effective silver concentration of 1·17 μ g ml −1 in NB and 0·29 μ g ml −1 in modified Tris minimal media), suggesting that entrapment of silver in a suitable matrix or its functionalization leads to efficient anti‐QS activity (Desai and Kowshik ; Desai et al . ; Naik et al . ).…”

Preparation of a magnetically separable CoFe2O4supported Ag nanocatalyst and its catalytic reaction towards the decolorization of a variety of dyes

“…folic-acid-functionalized AgCl/ TiO 2 (ref. 44) and Ag nanoparticle loaded mesoporous silica (SBA-15)) 45 exhibit high antibacterial activity against bacterial strains (Gram-positive; M. luteus, S. aureus and Gram-negative; E. coli, P. aeruginosa) and a fungal strain (C. albicans). The mechanism of the antimicrobial action of the Ag nanoparticles involves the binding of Ag + ions to the thiol (sulydryl) groups of proteins and enzymes, which causes inactivation and inhibition in cell processes.…”

Synthesis and Characterization of Antibacterial Photocatalytic Activated Carbon Black-Titanium Dioxide Composite Employing Ultrasonic Agitation Method

“…Currently, many TiO2 ̶ ̶ based composites with not only possessed antimicrobials activity but also belong to photocatalytic and anticancer activity have been successfully synthesized by using various counterpart matrices such as ZnO [16], Epoxy resin polymer [17], Polycaprolactone matrix [18], AgCl and Folic acid [19], SiO2 and ZrO2 [20] and so on. In these all cases, the role of the counterpart materials was to enhance the chemical and physical properties of TiO2 including its antibacterial and photocatalytic activity by decreasing its energy band gap reveal between VB and CB so that the electromagnetic visible light spectrum can force the VB electrons to jump into the CB surface.…”
