“…With regard to the chemical factor, it is important to note the absence of high-performance filtration systems ensuring 100% air purification. Industrial workers face the greatest risk levels, as they are exposed to numerous by-products, the most hazardous of which are ultrafine particles (<100 nm in size) that enter the environment and jeopardize the general population [ 1 ]. Moreover, exposure to nanoparticles may occur due to the extensive use of nanomaterials in engineering, different sectors of national economy, and medicine.…”

The main objective of this work was the production of novel polyvinylpyrrolidone/diacid modified Mg‐substituted fluorapatite (DM‐MFA) nanocomposites (NC)s, by sonication process. Mg‐substituted fluorapatite (MFA) powders with a chemical composition of Ca9.5Mg0.5(PO4)6F2 were prepared by mechanical alloying technique. Initially, surface of MFA was modified by bioactive chiral diacid monomer, N‐trimellitylimido‐l‐leucine as a coupling agent to form DM‐MFA nanoparticles. DM‐MFA NPs were utilized as a filler, to give the NCs with potential bioactivity. Examination of transmission electron microscopy (TEM), and field emission scanning electron microscopy (FE‐SEM) microphotographs displayed that, there is no aggregation of a large quantity of particles. The above NCs showed rather improved thermal stability compared with pure polymer. The improvement of thermal behavior was related to the uniform and good dispersion of DM‐MFA in the polymer matrix as well as the strong hydrogen bonding between CO of PVP and OH of DM‐MFA. © 2016 Wiley Periodicals, Inc.

Antimicrobial electrospun nanofibers of cellulose acetate and polyester urethane composite for wound dressing

et al. 2012

In this study, a series of nanofibrous membranes were prepared from cellulose acetate (CA) and polyester urethane (PEU) using coelectrospinning or blend-electrospinning. The drug release, in vitro antimicrobial activity and in vivo wound healing performance of the nanofiber membranes were evaluated for use as wound dressings. To prevent common clinical infections, an antimicrobial agent, polyhexamethylene biguanide (PHMB) was incorporated into the electrospun fibers. The presence of CA in the nanofiber membrane improved its hydrophilicity and permeability to air and moisture. CA fibers became slightly swollen upon contacting with liquid phase. CA not only increased the liquid uptake but also created a moist environment for the wound, which accelerated wound recovery. PHMB release dynamics of the membranes was controlled by the structure and component ratios of the membranes. The lower ratio of CA: PEU helped to preserve the physical and thermal properties of the membranes, and also reduced the burst release effectively and slowed down diffusion of PHMB during in vitro tests. The controlled-diffusion membranes exerted long-term antimicrobial effect for wound healing.
