“…It may be that the hemiacetal hydroxyl group in cellulose is reductive, which led to part of silver ions was reduced to nanosilver particles. Besides, PVP was also used as reducer in some reports, maybe the generation of nanosilver particles partly owed to the reducibility of PVP . In Fig.…”

A simple, green, and efficient microwave‐assisted heating method was developed to synthesize the cellulose/Ag nanocomposites by reducing silver nitrate in aqueous solution. The structure of nanocomposites was analyzed with X‐ray diffraction and Fourier transform infrared, the results showed that nanosilver particles were synthesized successfully on the surface of cellulose and did not change the structure of cellulose obviously. The shape and average size of silver nanoparticles and its distribution on cellulose fiber surface were observed by scanning electron microscopy, and the results demonstrated that the silver nanoparticles had a good distribution on the surface of cellulose fiber and high dosage of polyvinyl pyrrolidone decreased the size of nanosilver particles. Atomic absorption spectroscopy was used to measure the silver content in the composites, it was found that the silver content was higher in composites obtained by microwave heating compared with oil bath heating. The effect of silver nanoparticles on the thermal stability of cellulose fiber was studied by thermogravimetric analysis and differential scanning calorimetry, and it revealed that the silver nanoparticles had no obvious influence on the thermal stability of cellulose. The excellent antimicrobial activity against both Escherichia coli (gram‐negative bacteria) and Staphylococcus aureus (gram‐positive bacteria) showed a potential application in medical and health care field.

“…Recently silver nanoparticles became a fresh member of antimicrobial Ag family due to their higher specific surface area and high fraction of surface atoms compared to bulk Ag [40,41]. By means of mycelium growth rate, the results showed that, at the same conditions, the inhibition rates of Ag + , Ag (200 nm), and Ag (2 nm) against wheat phytoalexin were 15.47%, 25.46%, and 49.64%, respectively ( Figure 5).…”

This paper focuses on the synthesis of novel Ag nanoclusters (NCs) using DHLA as capping reagents in aqueous solution by a photoreduction method. Luminescence studies indicated that the DHLA-Ag NCs exhibited strong blue emission with maximum peak at 480 nm. The maximum emission of the NCs can be greatly improved with irradiating time by around 15-fold from 3 h to 67 h. By means of mycelium growth rate, the results showed that the Ag NCs with smaller sizes had a good antimicrobial effect.

“…Additionally, anti-bacterial coatings such as Ag/ND could be used as anti-contaminant implant co atings owing to their antimicrobial properties against E. coli 79 . The anti-microbial properties of NDs have been attributed due to the presence of oxygen-containing groups and charges on their surface [56].…”

Nanodiamonds (NDs) have been used in various fields of medicine such as drug delivery, tissue regeneration and gene therapy. Although there has been research carried out investigated the potential of these remarkable materials in dentistry, to date no review has been published to summarize the studies conducted.Due to their target cell specificity, small size and fluorescence they have also been found to be usefulness in dentistry. Main applications of NDs in dentistry and medicine include guided tissue regeneration, reinforcement of polymers and drug delivery to treat infections and cancers. Recent research also suggests that NDs can also be used as bioactive or antibacterial dental implant coatings. However, to date, the research conducted on their biocompatibility is limited and inconclusive. Hence, substantially more in vitro and in vivo studies are required to envisage the future of NDs in dentistry. It is hoped that in the next decade these promising materials will find a variety of uses in routine dentistry.
