“…The HA-Ag/SiO2/TiN/Ti coating presented a milder antibacterial effect, with close to 30% damaged bacteria at 2 h of contact, which increased to 40% at 4 h. Antibacterial properties of Ag incorporated in coatings have been found in the literature for release rates higher than those registered in the present work [13,57]. M.A.…”

“…Nanostructured materials doping has been useful for improve the structural and functional characteristics [14]. Specifically, antimicrobial activity can be conferred upon a biomaterial after doping with silver or copper through the release of these ions in the organism, antimicrobial mechanisms triggers membrane depolarization or generate SOS stress type in bacteria [15][16][17], however doping in implants is regulated by the ion lethal dose, plus the generated additional costs.…”

Advanced ceramics development is a promising area in regenerative medicine; although there are different biomaterials with features that make them viable enough, their improvement and optimization is required to produce biomaterials easier to bio assimilate and promote a faster tissue recovery. At this work a nanostructured bioglass based biomimetic scaffold is developed, beginning with the sol-gel synthesis parameters establishment coupled with a spray drying stage. through X-ray diffraction the crystal na 6 ca 3 si 6 o 18 phase was characterized, this phase is common to find in almost every 45s5 bioglass different synthesis processes, also a standard of mammalian hydroxyapatite was prepared to be used as a comparative control in determining the bioglass scaffold bioactivity. three-dimensional structure was characterized by optical and scanning electron microscopy, coupled to a semi-quantitative technique (eDs) to determine the composition of the synthesized biomaterial. subsequently, simulated body fluid (sBF) was used as an in vitro system, whose composition emulates the ionic blood concentration to evaluate the scaffold bioactivity.

Multi-purpose polyacrylamide (PAM) and polyacrylamide-co-sodiumpolyacrylate (PAM-co-NaPA) impregnated polyurethane foams (PUF) loaded with iodine have been prepared by in situ free radical polymerization. The prepared hydrogel networks displayed higher capacity for absorbing biological fluids as compared to regular PUF sheets and cotton matrices used in hospitals for maintaining hygiene conditions in cases of blood spillage and leakages. PAM-impregnated-PUF showed 910, 605, and 172% absorption in water, saline, and blood, respectively, whereas PAM-co-NaPA-impregnated-PUF showed absorption of 1545, 1395, and 269% in water, saline, and blood, respectively in 24 h. Exposure to nuclear, biological, and chemical (NBC) environment has become a grave predicament in today's world necessitating prevention of radiological contaminations especially in medical facilities. PAM-coNaPA-impregnated-PUF displayed 97% absorption of Tc 99 from whole blood whereas PUF sheets were highly hydrophobic and showed only 1% absorption of Tc 99 from whole blood. It was also demonstrated that modified foams have long-term broad-spectrum antimicrobial properties due to sustain release of ionic iodine. Thus, PAM-co-NaPA-impregnated-PUF sheets have strong potential to be used as matrices for carrying the injured patients, from field conditions to hospitals expose to NBC environment.
