“…Hydrolysis is the main mechanism involved in the degradation of antifouling binders. This reaction can be conducted through pendant ester groups in the case of acrylic polymers and copolymers or within the polymer backbone as in the cases of polylactides, polyamides, polyhydroxyalkanoates and polyanhydrides (Omae, 2003b;Yebra et al, 2004;Faÿ et al 2006Faÿ et al , 2007aFaÿ et al , 2007bFaÿ et al , 2007c. For (meth)acrylic copolymers bearing hydrolysable side ester groups in sea water, the reaction mechanism yields the conversion to sodium salt of some 18.3 CLSM micrographs of the cross-section of a rosin-based paint (a) and TBT-SPC coating (b) after two months of immersion in fl uorescein.…”

This Review compiles the synthesis, physical properties, and biomedical applications for the polyesters based on castor oil and ricinoleic acid. Castor oil has been known for its medicinal value since ancient times. It contains ∼90% ricinoleic acid, which enables direct chemical transformation into polyesters without interference of other fatty acids. The presence of ricinoleic acid (hydroxyl containing fatty acid) enables synthesis of various polyester/anhydrides. In addition, castor oil contains a cis-double bond that can be hydrogenated, oxidized, halogenated, and polymerized. Castor oil is obtained pure in large quantities from natural sources; it is safe and biocompatible.

“…Others focus on the use of metal-based coatings such as zinc pyrithione [ 17 , 18 ], zinc oxide [ 19 ], copper [ 20 ], titan dioxide [ 21 , 22 , 23 ], or silver [ 24 , 25 ]. Biocides such as diuoron, and Sea-Nine 211 were also effective [ 17 , 26 ]. Additionally, there is a vast amount of enzyme-based coating alternatives [ 27 ].…”

Millions of people use public transportation daily worldwide and frequently touch surfaces, thereby producing a reservoir of microorganisms on surfaces increasing the risk of transmission. Constant occupation makes sufficient cleaning difficult to achieve. Thus, an autonomous, permanent, antimicrobial coating (AMC) could keep down the microbial burden on such surfaces. A photodynamic AMC was applied to frequently touched surfaces in buses. The microbial burden (colony forming units, cfu) was determined weekly and compared to equivalent surfaces in buses without AMC (references). The microbial burden ranged from 0–209 cfu/cm2 on references and from 0–54 cfu/cm2 on AMC. The means were 13.4 ± 29.6 cfu/cm2 on references and 4.5 ± 8.4 cfu/cm2 on AMC (p < 0.001). The difference in microbial burden on AMC and references was almost constant throughout the study. Considering a hygiene benchmark of 5 cfu/cm2, the data yield an absolute risk reduction of 22.6% and a relative risk reduction of 50.7%. In conclusion, photodynamic AMC kept down the microbial burden, reducing the risk of transmission of microorganisms. AMC permanently and autonomously contributes to hygienic conditions on surfaces in public transportation. Photodynamic AMC therefore are suitable for reducing the microbial load and closing hygiene gaps in public transportation.
