“…This enhancement in wear resistance can be associated with improved hardness (table 5). It can be said that the boron addition to the coating increased the coating density thus increasing the hardness of the coating, which is in accordance with the studies that evaluated the boron-doped coatings [69,[105][106][107]. Additionally, it is clear from figure 8(e) and figure 8(f) that the coated layer is still intact in some areas inside the wear tracks of HA-B samples.…”

Plasma electrolytic oxidation coupled with hydrothermal treatment is a relatively new technique to form a hydroxyapatite/TiO2 layer on titanium alloys for biomedical applications. Hence the process allows achieving a bioactive and bactericidal surface by using electrolytes that contain ions (such as calcium-phosphorus and boron) necessary for desired properties. The coating properties are controllable by adjusting the parameters in the PEO process. In the present study, an electrolyte that contains both calcium, phosphorus, and boron ions was used to form a rough and porous oxide layer on Ti6Al7Nb which is known to be less toxic than the most widely used Ti alloy for biomedical applications, Ti6Al4V. A hydroxyapatite and boron-containing oxide layer was obtained after plasma electrolytic oxidation and hydrothermal treatment. Coatings were examined by XRD, XPS, SEM, contact angle measurement system, micro-hardness tester, wear tester, and corrosion measurement system. The results showed that the wear and the corrosion properties of all coated samples increased. Especially boron doping enhanced both the wear and corrosion resistance. Relatively the best corrosion resistance was achieved from CaP-B and the best wear resistance was from HA-B samples. The hardness values and mean surface roughness of all coated samples also increased while the average friction coefficients decreased. The hardness increased from 323 ± 5 HV0.1 to 1084 ± 16 HV0.1 where the coefficient of friction decreased from 0.5672 ± 0.01 to 0.4697 ± 0.03.

“…These scaffolds were prepared using emulsion freeze-drying, [153] phase separation, [154] electrospinning, [149] and 3D printing. [152] Third, h-BN can form a biocomposite coating through strong interface bonding with hydroxyapatite, [155,156] gelatin, [157] etc., which enhances bone tissue healing and bone formation. Yoo et al used hyperbranched polyglycerol (HPG) to functionalize BNNS and gelatin to synthesize an artificial pearl layered material (HPG-g-BNNS), which shows excellent mechanical strength similar to human cortical bone with the biological activity to induce cell differentiation.…”

Hexagonal boron nitride (h‐BN) nanomaterials are a rising star in the field of biomedicine. This review presents an overview of the progress in h‐BN nanomaterials for biological applications. It begins with a general introduction of the structural characteristics of h‐BN, followed by the brief introduction of its physical and chemical properties, including thermal, band and mechanical properties, chemical reactivity, biodegradability and biocompatibility, then emphasizes on the recent progress in the biomedical applications including drug delivery, boron neutron capture therapy (BNCT), bioimaging and nanozyme, and ends with the challenges and perspectives related to the biomedical applications. The advantages of BN nanomaterials used for biomedical applications were analyzed, and their problems were also discussed, inspiring the future rational designs of the BN nanomedicines.

“…Considering all the above-mentioned properties, BN has been used as an antimicrobial coating material for biomedical implants. Yenal et al have used wollastonite and BN-doped, hydroxyapatite-based HAp-Wo-BN composite coatings on the surface of Ti 6 Al 4 V where BN was used for its bone tissue healing and antimicrobial property . A very recent study also has reported the antimicrobial action of BN in a coating material made of boron nitride nanosheets containing a chitosan-based coating on a Mg alloy where BN has showed its antimicrobial property against E.…”

Recently, the upsurge in hospital-acquired diseases has put global health at risk. Biomedical implants being the primary source of contamination, the development of biomedical implants with antimicrobial coatings has attracted the attention of a large group of researchers from around the globe. Bacteria develops biofilms on the surface of implants, making it challenging to eradicate them with the standard approach of administering antibiotics. A further issue of current concern is the fast resurgence of resistance to conventional antibiotics. As nanotechnology continues to advance, various types of nanomaterials have been created, including 2D nanoparticles and metal and metal oxide nanoparticles with antimicrobial properties. Researchers from all over the world are using these materials as a coating agent for biomedical implants to create an antimicrobial environment. This comprehensive and contemporary review summarizes various metals, metal oxide nanoparticles, 2D nanomaterials, and their composites that have been used or may be used in the future as an antimicrobial coating agent for biomedical implants, as well as their succinct mode of action to combat biofilm-associated infection and diseases.
