“…In another study, incorporation of Ag 2 O into a bioactive glass enabled antimicrobial properties without compromising its bioactivity [124]. Antibacterial surfaces are of particular interest for reducing biomaterial-centered infection and, thereby, enhancing tissue integration and bone regeneration [124,143,144].…”

Critical-sized bone defects have, in many cases, posed challenges to the current gold standard treatments. Bioactive glasses are reported to be able to stimulate more bone regeneration than other bioactive ceramics; however, the difficulty in producing porous scaffolds made of bioactive glasses has limited their extensive use in bone regeneration. On the other hand, calcium phosphate ceramics such as synthetic hydroxyapatite and tricalcium phosphate are widely used in the clinic, but they stimulate less bone regeneration. This paper gives an overview of the recent developments in the field of bioactive nanoparticles, with a focus on nanohydroxyapatite and bioactive glasses for bone repair and regeneration. First, a brief overview of the chemical structure and common methods used to produce synthetic nanohydroxyapatite and bioactive glasses has been presented. The main body of the paper covers the physical and biological properties of these biomaterials, as well as their composites with biodegradable polymers used in bone regeneration. A summary of existing challenges and some recommendations for future directions have been brought in the concluding section of this paper.

“…Novel systems allowing controlled release of components are intensely investigated and various inorganic antibacterial materials containing silver (glasses, vitroceramics, composites) have been developed and some of them are already in the commercial use [10][11][12][13]. The vanadium oxide nanotubes (Ag/VO x -NT x ) modified by highly dispersed Ag nanoparticles proved also to have a strong antibacterial activity [14].…”

Structural investigation of V2O5–P2O5–K2O glass system with antibacterial potential

The xV 2 O(1 − x)[0.8 P 2 O 5 • 0.2 K 2 O] glass system with 0 ≤ x ≤ 50 mol% was prepared and the structural changes induced in these glasses by increasing the vanadium oxide content were investigated by IR and ESR spectroscopies. The dual behaviour role of V 2 O 5 oxide, as network modifier (for x ≤ 10 mol%) and the network former (x ≥ 20 mol%), as a consequence of phosphate network depolymerization and P-O-V and V-O-V linkages appearance was also highlighted. The antibacterial effect of the glasses with x ≤ 20 mol% V 2 O 5 content was tested by optical density (OD) measurements. A linear correlation between the amount of vanadium and the antibacterial effect was evidenced.

“…The antibacterial effect of bioactive glasses doped with AgNP was demonstrated in many studies [ 112 , 113 , 114 ]. Magyari et al [ 112 ] tested the antibacterial activity of borophosphate glasses with silver oxide (Ag 2 O) content using Listeria monocytogenes .…”

“…Vulpoi et al [ 114 ] tested antibacterial activity of the composite of polymer-bioactive glass with Ag 2 O on genetically modified light-emitting bacteria Escherichia coli and Staphylococcus epidermidis by measuring the bioluminescence of the indicator strains ( Figure 6 ). It was discovered that the polymer-bioactive glass composite with Ag content showed bactericidal effect, while inhibition of bacterial growth was also proved for the Ag-free polymer-bioactive glass composite.…”

Surface Plasmon Resonance or Biocompatibility—Key Properties for Determining the Applicability of Noble Metal Nanoparticles

et al. 2017

View full text Add to dashboard Cite

Metal and in particular noble metal nanoparticles represent a very special class of materials which can be applied as prepared or as composite materials. In most of the cases, two main properties are exploited in a vast number of publications: biocompatibility and surface plasmon resonance (SPR). For instance, these two important properties are exploitable in plasmonic diagnostics, bioactive glasses/glass ceramics and catalysis. The most frequently applied noble metal nanoparticle that is universally applicable in all the previously mentioned research areas is gold, although in the case of bioactive glasses/glass ceramics, silver and copper nanoparticles are more frequently applied. The composite partners/supports/matrix/scaffolds for these nanoparticles can vary depending on the chosen application (biopolymers, semiconductor-based composites: TiO2, WO3, Bi2WO6, biomaterials: SiO2 or P2O5-based glasses and glass ceramics, polymers: polyvinyl alcohol (PVA), Gelatin, polyethylene glycol (PEG), polylactic acid (PLA), etc.). The scientific works on these materials’ applicability and the development of new approaches will be targeted in the present review, focusing in several cases on the functioning mechanism and on the role of the noble metal.
