Antimicrobial activity of tellurium‐loaded polymeric fiber meshes

Abstract

A series of poly(methyl methacrylate) solutions loaded with varying concentrations of tellurium particles are prepared and processed into continuous and smooth microfiber meshes. Scanning electron microscopy and energy-dispersive X-ray spectroscopy are used to study the morphology and surface elemental composition of the composite fibers. Fiber diameters range between 7 and 14 mm with surface nanopores on the fibers ranging between 100 and 200 nm. Energy-dispersive X-ray spectroscopy confirmed successful incorporation of tellurium particles into the fibers. The concentration of tellurium in the composite significantly influenced fiber diameter, pore size, and morphology. The antibacterial activity of the prepared fibers is tested using Escherichia coli K12. The fibers are incubated in bacterial suspensions for 24 h at 37 8C and 150 rpm. Antibacterial activity is assessed through the colony-counting method and is found to be dose dependent. The fibers with 4 wt % tellurium exhibited the most potent antibacterial properties as a 1.16 log reduction was observed.

Developments in Pressurized Gyration for the Mass Production of Polymeric Fibers

“…As infectious diseases and antibiotic resistance become increasingly prevalent, there is greater focus on ultrafiltration with the incorporation of nanoparticles . To produce antimicrobial ultrafiltration systems for air, tellurium (Te) nanoparticles were embedded into a PMMA mesh using PG . Porous PMMA fibers with 1, 2, and 4 wt% Te particles were prepared, and SEM was used to confirm dispersion of antimicrobial Te particles.…”

“…[103,104] To produce antimicrobial ultrafiltration systems for air, tellurium (Te) nanoparticles were embedded into a PMMA mesh using PG. [105] Porous PMMA fibers with 1, 2, and 4 wt% Te particles were prepared, and SEM was used to confirm dispersion of antimicrobial Te particles. Increased concentration of Te particles led to wider diameter fibers, from 0% loaded Te fibers having diameters of 7.06 ± 3.77 µm to 4% loaded Te fibers having diameters of 13.9 ± 7.05 µm.…”

Development and characterization of ceftriaxone-loaded P3HB-based microparticles for drug delivery

“…To overcome these problems various approaches are developed including the use of immobilized biologically active agents, such as fullerenes, carbon nanotubes, graphite, nanodiamonds, graphene oxide, metal oxides' nanoparticles, and metalloids, which may be used for bacterial infections treatment. 4,5 The mechanism by which nanostructured materials inactivate bacteria is complex and depends on intrinsic properties materials, for example, composition and surface modification, the nature of the target microorganisms, and the characteristics of the environment in which cell-materials interactions take place. 6 Another popular approach to increase the effectiveness of antibiotic therapy is the use of antibacterial drugs in the form of microcarriers and nanocarriers.…”
