“…It is known that surface topography is one of the multiple factors that can influence how bacteria interact with surfaces. As discussed in our previous work where antibiofilm coatings with R a in the ranges of 373–503 nm [ 16 ] and 398–560 nm [ 17 ] were produced, the generation of different topographies has different effects. For instance, rough surfaces can magnify surface hydrophilicity to the point that bacterial cells are repelled by surface hydration, and they can reduce the contact area between the bacteria and the surfaces.…”

“…[ 12 ] Also, as discussed in our previous publications, strong hydrophilic surfaces (WCA < 20°) can reduce biofilm formation through the generation of a hydration layer that acts as a barrier against the attachment of bacterial cells and proteins. [ 16–18 ]…”

“…In some of our most recent publications, functional coatings that were deposited by an APPJ system using acrylic acid as the precursor reduced the formation of biofilm of several bacterial species on 3D‐printed [ 16,17 ] and stainless steel substrates. [ 18 ] According to our observations, the strong hydrophilic character of those coatings (WCA < 20°), which promotes the generation of a hydration layer that acts as a barrier against the attachment of bacterial cells and proteins, was the key to their effectiveness at reducing biofilm formation.…”

Biofilms pose important economic and health risks in biomedical applications and in food industries. In this study, coatings that reduce the biofilm formation of Pseudomonas aeruginosa on polystyrene cell culture plates are deposited by plasma polymerization of (3‐aminopropyl)triethoxysilane using an atmospheric pressure plasma jet system at three different power levels. Surface characterizations and quantification of biofilm formation during 1 week after deposition suggest that the higher concentration of oxygenated carbon groups on the coated samples than on uncoated ones can induce higher levels of oxidative stress in the bacteria in contact with the coatings. This causes an initial overproduction of extracellular polymeric substances that can avoid further bacterial attachment and biofilm formation at later cycles of biofilm development.

Healing of bone fractures highly depends on the biocompatibility, stability in biological conditions, biodegradability, technical functionality, and shelf‐life of biomaterials. Metallic biomaterials offer excellent mechanical properties and biocompatibility. However, metallic bone implants result in stress shielding, release of toxic ions, excessive wear, and corrosion. Polymer materials are being explored for bone implants due to their light‐weight, biocompatibility, biodegradability, and absence of stress shielding. In the new era, additive manufacturing (AM) is being preferred due to its capability of fabricating customer specific implants with minimum material wastage. However, AM based polymer implants lack in mechanical strength and biological properties. Surface modification of polymeric substrates using coatings and incorporation of bioadditives have been regarded as alternatives for improvement of mechanical and biological properties. This review discusses about various coating techniques and gives an overview about coatings and bioadditives that can be used for enhancement of properties. From the review, it is evident that reinforcement of hydroxyapatite to polylactic acid resulted in prevention of crack growth during shape recovery cycles which can be used for self‐fitting implants. Coatings have been successful in enhancing hydrophilicity, mechanical properties, anti‐biofouling, antibacterial and anti‐coagulative properties, adhesion, proliferation, and differentiation of cells on the coated surface. This review also discusses the challenges that need to be overcome for progression in this field.
