“…Namely, hydrophobic surfaces can be turned to hydrophilic, while hydrophilic materials become hydrophobic [130] after immersion in an aqueous solution of hydrophobin. Textile materials can be finished with various functionalization agents, such as chitosan microcomposites [131] or nanocomposites [132,133], medicinal herbs [134], nisin [135], polyhexamethylene biguanide [136], or PMMA nanocomposites [137], in order to obtain new surface properties like antimicrobial, hydrophobicity, resistance to laundering, or protection against decoloration. Due to exceptional surface properties and to the tuning opportunities, their use is envisaged in cosmetic industry, polymer emulsion synthesis, and biosensing [138].…”

There are many studies in literature concerning contact angle measurements on different materials/substrates. It is documented that textiles can be coated with multifunctional materials in form of thin films or nanoparticles to acquire characteristics that can improve the protection and comfort of the wearer. The capacity of oxide nanostructures to inhibit fungal development and neutralize bacteria is a direct consequence of their wetting behavior [1-6]. Moreover, the radical modification of wetting behavior of nanostructures from hydrophilic to hydrophobic when changing the pulsed laser deposition (PLD) ambient will be thoroughly discussed. When an implant is introduced inside the human body, its surface is first wetted by the physiological fluids. This further controls the proteins adsorption followed by the attachment of cells to the implant surface. Hence, surface wettability is considered an important criterion that dictates biocompatibility of the implant and could stand for a decisive factor for its long-term stability inside the human body. In Section 1 of this chapter, the reader is briefly introduced to wetting phenomenon, and correlations between well-known Young, Cassie, and Wenzel approaches are made. Next, one of the most spread techniques to measure the wettability of surface, the contact angle measurement, is thoroughly explained and relevant examples are given. Section 2 begins with a summarized table about previous works on synthesis of hydrophobic or hydrophilic nanostructures with a special focus on ZnO, SiO x , TiO 2 , and DLC materials. A short presentation of the advantages of their synthesis by PLD, sol-gel, thermal evaporation, solution based on chemical approaches, sputtering, and plasma enhanced chemical vapor deposition will be introduced.

“…This produces extracellular polysaccharides, resulting in the formation of a biofilm and eventually leading to infections . A promising strategy to overcome the barrier is the fabrication of biomaterials with proper antimicrobial surfaces, such as surfaces with designed micropatterns, surfaces with attached chemical groups, and surfaces with coatings incorporating antibiotics via novel physical and/or chemical methods …”

An innovative antibacterial thin film with imbedded silver nanoparticles (AgNPs) is investigated through atmospheric pressure plasma deposition. The process is based on a single‐step fabrication of nanocomposite films where AgNPs are fed directly into the discharge zone. The morphology and stoichiometry of the thin films, characterized with SEM/EDX, GD‐OES, and XPS, can be tailored by the plasma parameters and the quantity of introduced AgNPs. An exceptional 32 at% of AgNPs is reached in the work. The antibacterial assays using Escherichia coli and Staphylococcus aureus strains show effective antibacterial activity of the films and indicate that the fabrication of nanocomposite films using atmospheric pressure plasma represents a feasible way to overcome the issue of device related infection.

“…Therefore, there is a reduction in zeta potential as pH increases, which tends toward the zeta potential of untreated PET at a very high pH of 10. Indeed, the isoelectric pH corresponding to a neutral structure of untreated PET is reached at pH z 4 [30]. Fig.…”
