The biological resistance and the environmental issues of biocide influence researchers to develop environmental-friendly biocides. Scientists from the US Naval Research Laboratory, Massachusetts Institute of Technology and Penn State University recently engineered a water-repellent film by a process that deposits nanorods on a thin film. Scientists at Rensselaer Polytechnic Institute demonstrated a biocidal effect by inserting lysostaphin, a naturally occurring microbial-derived defensive enzyme, in a carbon nanotube. Poseidon scientists have entered into R&D collaboration with Selenium Ltd (Texas) in developing new applications using covalently bonded selenium that can be permanently attached to the surface and continue to be biologically active. Se is a nutritional supplement and also possesses anti-bacterial properties through the release of reactive oxygen species, such as hydrogen peroxide. Poseidon-Selenium collaboration is aimed at developing coating technologies that would prevent fouling without the need for biocidal treatment.

The current regulatory trends, environmental safety and tests that generate a better estimation of the safety of a given coating or coating additive are discussed. The pharmaceuticals, chemicals and cosmetics industries have been inundated with regulations, public backlash and unwanted attention from environmental groups because of chemicals that are perceived as environmentally unfriendly. The key phrase that affects the marine paint industry those policymakers has discretionary decisions in situations where there is evidence of potential harm in the absence of complete information. Coatings comprise a diversity of polymers and a myriad of other additives. There are standardized methods in testing toxicity, such as the ASTM (American Society for Testing and Materials) E729- 1996 (re-approved 2002) in the USA and other similar methods in Japan and the EU. Also needed is to evaluate the coatings after longer periods of operational use to determine if such coatings retained a level of toxicity to other non-target animals.

Various studied are being conducted to study the potential of covalently bound selenium (Se) for its potential for hydraulically fractured wells. Texas Tech University (TTU) system has developed a green technology called SeLECT, marketed under the SeGuard brand. The technology works on the principle that selenium is bound permanently to the coating and yet remains bioactive and as such do not have to leave the surface to exert its antimicrobial action. Poseidon Sciences and Selenium Ltd. entered into a strategic partnership to develop coatings containing covalently bound Se. In an another work, a culture of the iron bacteria Gallionella sp was undertaken at Poseidon Sciences' facilities, making it possible to develop a bioassay to evaluate the performance of SeGuard. A second experiment conducted in which Se-treated and untreated immersed in a Gallionella-rich culture for 14 days at 86°F under anaerobic conditions, showing that the control washers demonstrate the beginnings of corrosion compared to the Se-coated surfaces.
