Bioburden control in biopharmaceuticals and single-use technology

In the first part of this series on bioburden control, Chris Davis defined biopharmaceutical products, outlined the risks inherent in biopharmaceutical processes and examined how to prevent microbial contamination. In this concluding part, he examines the control measures that can be applied to the process, such as steam-in-place and hot-water sanitisation, and the increasing use of single-use technology. The bioburden control measures applied to the process are listed in Table ...

Researcher engineers clean water-treatment option to target sporadic outbreaks

A University of Cincinnati (UC) researcher has engineered an environmentally friendly technology to zap outbreak-causing viruses and bacteria from public drinking water. Environmental and biomedical engineer David Wendell, an associate professor in UC's College of Engineering and Applied Science, developed a protein-based photocatalyst that uses light to generate hydrogen peroxide to eliminate E. coli, listeria, and potentially protozoa like giardia and cryptosporidium. If mass ...

Bioburden control in biopharmaceuticals: managing the risks

The last twenty years has seen significant investments in biopharmaceutical manufacturing in Ireland and this is set to continue with the likes of BMS, Pfizer, Eli Lilly, Regeneron, Shire and Alexion all undertaking major biopharmaceutical capital projects in Ireland. Adequate bioburden control is of paramount importance to the production of biopharmaceuticals and this is achieved through proper equipment preparation, a combination of cleaning, steaming-in-place (SIP) and hot water ...

Engineering polymer brush patterns: quicker and more versatile methods

Antimicrobial cutting boards. Flame-retardant carpets. Friction-resistant bearings. Engineered surfaces add value to the things we use, providing extra layers of safety, easing their operation, preserving their quality or adding utility. At UC Santa Barbara, materials researchers are looking to greatly improve on the concept with a method of micron-scale surface chemical patterning that can not only decrease time and money spent in their manufacture, but also add versatility to their ...

Successful water treatment – setting the scales straight

Conducting effective ongoing maintenance of commercial and industrial water-treatment systems requires attention to detail, customisation and preparation to ensure that the scales are perfectly balanced at all times. Similar to humans, each water system is different to the next, requiring tailored treatments that are individual to each independent system. This is where continuous and accurate monitoring provides the perfect balance. Direct analysis response technology (DART) constantly ...

The importance of properly classifying chemical substances and mixtures

The United Nations (UN) estimates that there are over 100,000 chemicals present on the global market, some 20,000 of which are considered to be dangerous. Given this extensive use of dangerous chemicals on the global market, a global approach to their safe use, transport and disposal is imperative. The protection of human health and the environment has been a primary focus of the UN for many years, specifically addressed in Agenda 21, which originated at the Rio Earth Summit in ...
