“…Hence, it is evident that the antibacterial activity of the present work can be improved via doping and the approach is highly safe to use for biological applications. This is important to emphasize as chemical synthesized nanoparticles may lead to toxic or side effects due to the existence of toxic chemicals [60]. The antibacterial mechanism of CB-Hap NRs may involve (i) the size-mediated penetration of nanorods into the bacterial cell wall to interact with the cellular biomolecules that increases the osmotic potential and its associated irreversible damage and (ii) the generation of free reactive oxygen species (ROS) radicals that are induced by nanorods that interact with the bacterial membrane and result in oxidative stress [61].…”

Cuttlefish bones are an inexpensive source of calcium carbonate, which are produced in large amounts by the marine food industry, leading to environmental contamination and waste. The nontoxicity, worldwide availability and low production cost of cuttlefish bone products makes them an excellent calcium carbonate precursor for the fabrication of hydroxyapatite. In the present study, a novel oil-bath-mediated precipitation method was introduced for the synthesis of hydroxyapatite (Hap) nanorods using cuttlefish bone powder as a precursor (CB-Hap NRs). The obtained CB-Hap NRs were investigated using transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA) techniques to evaluate their physicochemical properties. The crystallite size (20.86 nm) obtained from XRD data and the elemental analysis (Ca/P molar ratio was estimated to be 1.6) showed that the Hap NRs are similar to that of natural human bone (≈1.67). Moreover, the FTIR data confirmed the presence of phosphate as a functional group and the TGA data revealed the thermal stability of Hap NRs. In addition, the antibacterial study showed a significant inhibitory effect of CB-Hap NRs against S. aureus (zone of inhibition – 14.5 ± 0.5 mm) and E. coli (13 ± 0.5 mm), whereas the blood compatibility test showed that the CB-Hap NRs exhibited a concentration-mediated hemolytic effect. These biogenic CB-Hap NRs with improved physicochemical properties, blood compatibility and antibacterial efficacy could be highly beneficial for orthopedic applications in the future.

“…16 Nanomaterials possess relatively higher degrees of chemical, physical and biological activities due to their large surface area with respect to their bulk counterparts. [17][18][19][20][21] Among nanomaterials, titanium dioxide (TiO 2 ) is still a very promising candidate for light-assisted photocatalysis and degradation of many kinds of pollutant present in wastewater. 22 TiO 2 nanoparticles (NPs) are chemically active, abundant, non-toxic and possess satisfactory photocatalytic activity.…”

“…These nanomaterials possess significant properties, such as chemical compositions similar to teeth and its components, wettability, surface energy, and surface roughness, which makes them highly beneficial for the dental applications (Rasouli et al, 2018). However, the chemicals used for the fabrication of these nanomaterials are toxic toward human cells and high energies are involved in the nanomaterial formation, which has been identified as potential limitations to recommend them for large-scale commercial dental implant applications (Jeevanandam et al, 2020b). The toxicity of these chemical or physical synthesized nanomaterials depends on the type of reducing and stabilizing agent used for nanomaterial fabrication, size, morphology, and surface functional groups as well as their surface charge of nanomaterials (Ganguly et al, 2018;Qu et al, 2018).…”

Dental implants resemble synthetic materials, mainly designed as teeth-mimics to replace the damaged or irregular teeth. Specifically, they are demarcated as a surgical fixture of artificial implant materials, which are placed into the jawbone, and are allowed to be fused with the bone, similar to natural teeth. Dental implants may be categorized into endosteal, subperiosteal, and zygomatic classes, based on the placement of the implant “in the bone” or on top of the jawbone, under the gum tissue. In general, titanium and its alloys have found everyday applications as common, successful dental implant materials. However, these materials may also undergo corrosion and wear, which can lead to degradation into their ionic states, deposition in the surrounding tissues, as well as inflammation. Consequently, nanomaterials are recently introduced as a potential alternative to replace the conventional titanium-based dental implants. However, nanomaterials synthesized via physical and chemical approaches are either costly, non/less biocompatible, or toxic to the bone cells. Hence, biosynthesized nanomaterials, or bionanomaterials, are proposed in recent studies as potential non-toxic dental implant candidates. Further, nanobiomaterials with plant origins, such as nanocelluloses, nanometals, nanopolymers, and nanocarbon materials, are identified to possess enhanced biocompatibility, bioavailability and no/less cytotoxicity with antimicrobial efficacy at low costs and ease of fabrication. In this minireview, we present an outline of recent nanobiomaterials that are extensively investigated for dental implant applications. Additionally, we discuss their action mechanisms, applicability, and significance as dental implants, shortcomings, and future perspectives.
