“…[1][2][3] The antimicrobial properties of copper alloy surfaces makes them the preferential material for touch surfaces e.g. 5 Copper doped CaSiO 3 coatings have been investigated to provide antimicrobial properties to titanium surfaces of metallic implants. 4 Doping of paints with copper particles of different sizes demonstrated the highest antifouling potential when nano-particles were used, e.g.…”

Copper(i)oxide microparticles – synthesis and antimicrobial finishing of textiles

et al. 2015

Copper containing particles are of high interest to provide antibacterial activity to textiles for medical products, hygiene application or where odor formation as result of bacterial activity has to be controlled. Cu(I)oxide microparticles with a rather uniform diameter between 1.5 and 2 µ m can be prepared by controlled reduction of alkaline Cu(II)-tartaric acid complexes. Such particles can be bound to textile surfaces by means of a pigment binder system used in pigment dyeing. By a simple pad-dry process textile fabrics with a Cu-content of 250 -270 mg Cu / kg fabric could be prepared. The samples (fabrics) exhibited a reduction in viability of 100 % for Staphylococcus aureus and 84 % for Klebsiella pneumonia as estimated by the ASTM E2149 antimicrobial test. Simulated wash procedures led to a reduction in Cu-content to 60 -50 % of the initial value. Reduction in viability remained at 99 % for Staphylococcus aureus and 78 % for Klebsiella pneumoniae. The new process is of high value to impart antimicrobial properties to textile products because an antimicrobial product with good wash permanence can be delivered using rather simple processing and ordinary chemicals.

“…The visual make-up of the polymer using electron microscopy was still "smooth" and, thus, little changes in water contact angle are shown. [9][10][11]18] In all cases, the plasticizer has reduced the water contact angle of the polymer (n ¼ 10 AE 1 SD). Figure 3 shows that the full range of plasticizers has reduced the overall superhydrophobic water contact angle of the polymer.…”

“…[6] The plasticizer enables interruption of the vinyl chloride repeating unit polymer chains and enables the property of PVC to be changed from brittle to more pliable. [9] A surface, which possesses superhydrophobicity has a small contact area between the solid and water interface inducing water resistance and, thus, "fouling" [10,11] or attachment of certain molecules. Typically, PVC has a water contact angle of 90 .…”

Here we show an easy to synthesize superhydrophobic material using a solvent phase-separation process of poly vinyl chloride. It is found that solvents mixed in different ratios increase the dielectric value of the solvent and can be tuned to produce superhydrophobic PVC. The PVC solution is then spin-coated onto glass slides for characterization using scanning electron microscopy. Plasticizers are doped into the 70% (v/v) PVC to determine their overall effects; it is found that plasticizers reduce the water contact angle value. The final coatings were tested in a series of antifouling assays in a marine environment lab study; it is found that the superhydrophobic PVC material reduced marine biofouling.

“…Critically, the importance of being able to quantify baseline levels of the detachment phase during a biofilm cultivation experiment in order to study the actual effect of remediation or mitigation techniques (i.e., increased shear, biocidal agents [3,4,[14][15][16]) is extremely important. Previously, authors have demonstrated that detachment occurred only when the biofilm was fully formed-however, this is incorrect and detachment can occur at any time of the biofilm formation process.…”

The rheological properties of biofilms have a great impact on major processes such as transport of nutrients, light, biocides, water, biochemicals and cells. The knowledge of the mechanical properties of biofilms is essential in quantifying the overall process of biofilm development and bacterial survival (and proliferation)-one of the key processes in a biofilm lifecycle is detachment. It is therefore crucial to be able to predict the biofilm detachment and break up in response to internal and external forces that drive the biofilm cycle. This chapter aims to highlight some of the important processes in the biofilm detachment cycle. It will also draw on some new and old concepts on this age old battle of biofilm survival and proliferation.
