“…This was the motivation behind the development of bioinspired superhydrophobic materials for antimicrobial coating . The successful repulsion and removal of microbial colonies, such as E. coli , Streptococcus mutans , P. aeruginosa , and S. aureus or any Gram-positive or Gram-negative bacteria, from different superhydrophobic surfaces have been carried out, − which shows the importance of superhydrophobic surfaces or coatings for antimicrobial repellence.…”

The ongoing worldwide pandemic due to COVID-19 has created awareness toward ensuring best practices to avoid the spread of microorganisms. In this regard, the research on creating a surface which destroys or inhibits the adherence of microbial/viral entities has gained renewed interest. Although many research reports are available on the antibacterial materials or coatings, there is a relatively small amount of data available on the use of antiviral materials. However, with more research geared toward this area, new information is being added to the literature every day. The combination of antibacterial and antiviral chemical entities represents a potentially path-breaking intervention to mitigate the spread of disease-causing agents. In this review, we have surveyed antibacterial and antiviral materials of various classes such as small-molecule organics, synthetic and biodegradable polymers, silver, TiO2, and copper-derived chemicals. The surface protection mechanisms of the materials against the pathogen colonies are discussed in detail, which highlights the key differences that could determine the parameters that would govern the future development of advanced antibacterial and antiviral materials and surfaces.

“…The coating exhibits excellent robustness under mechanical abrasion or impact damage (1600 to 20,000 cm) (Zhang et al 2019b). Q. Cheng et al have prepared the micro-nanostructure superhydrophobic SiO 2 coating through a facile spray-coating method with the contact angle (CA) of 155.9 and the sliding angle (SA) less than 1 with good transparency properties (Cheng et al 2019 Fig. 3 Schematic image of the various methods for coating (Wu et al 2016) and exhibit the hydrophobic behavior without any surface modification or treatment (Kumar et al 2011a).…”

This chapter is based on the recent literature on the superhydrophobic surface coated using various kinds of nanostructured materials (such as metal oxide and composite) and surface functionalizaton. Superhydrophobic surfaces repel water generally due to their surface texture or chemical properties, and surface possesses a high apparent contact angle (>150) and very low sliding angle (<5). Superhydrophobic coatings have received great attention worldwide for its multifunctional application in automotive, marine, and building sector.

“…These characteristics made such coatings to be acknowledged by selfcleaning surfaces and the photocatalytic characteristic of these materials, which allows their use in several types of surfaces, including the oral environment (Cheng et al, 2019;Kamegawa et al, 2012). In Dentistry, the biocompatibility of TiO 2 coating has been tested to induce antimicrobial properties in surfaces, cement, and resins (Fatani et al, 2017;Salehi et al, 2018).…”

“…Among the NPs, the titanium dioxide (TiO 2 ) and silica dioxide (SiO 2 ) have gained attention in the food, textile, automotive, and aviation industries and in the biological control of surfaces due to their hydrophobic properties, preventing the adherence of dirt and bacteria. These characteristics made such coatings to be acknowledged by self‐cleaning surfaces and the photocatalytic characteristic of these materials, which allows their use in several types of surfaces, including the oral environment (Cheng et al, 2019; Kamegawa et al, 2012). In Dentistry, the biocompatibility of TiO 2 coating has been tested to induce antimicrobial properties in surfaces, cement, and resins (Fatani et al, 2017; Salehi et al, 2018).…”

Several mechanical and biological factors may change the orthodontic wire frictional resistance (FR). Titanium dioxide (TiO2) and silica dioxide (SiO2) nanoparticle (NP) coatings may be used to improve the characteristics of materials, reducing FR between archwire and bracket. This in vitro study aimed to evaluate the FR of orthodontic wires with and without coating in both dry and wet environments and measure the surface roughness (SR). One hundred and eighty segments of rectangular Cr–Ni orthodontic wires (Morelli Co, Brazil) were divided into three groups according to the NP coating applied: TiO2 group; SiO2 group; and control group. The SR parameters were measured in an optical profilometer, the surface morphology was analyzed with scanning electron microscopy (SEM), and FR was performed in a universal testing machine in dry and wet environments (n = 30). The statistical analysis was performed using the Generalized Estimated Equations model with a Bonferroni post‐test (α = 0.05). It was observed that SiO2 NP coating decreased FR significantly when compared to the TiO2 and control groups, in both environments (p < .001). The SiO2 and TiO2 groups presented statistically lower SR than the control group and were similar to each other (p < .001). The SiO2 group presented the lower depth of Valley parameter than the TiO2 group (p < .001). The SEM showed that the TiO2 coating had the most heterogeneous surface morphology than the SiO2 and control groups. The orthodontic wires with NP coating modified the FR and morphology. The SiO2 coating reduced FR in both dry and wet environments and decreased SR. Titanium dioxide (TiO2) and silica dioxide (SiO2) nanoparticles coatings may be used to reduce frictional resistance (FR) between archwire and bracket as well as to improve surface morphology. The SiO2 coating reduced FR in both dry and wet environments and decreased the SR of Cr–Ni orthodontic wire. The TiO2 coating promoted the most heterogeneous surface morphology of Cr–Ni orthodontic wire.
