Single-Use Technologies: Bridging Polymer Science to Biotechnology Applications
During the last decade, single-use bioreactors or storage vessels made of flexible bags have been well-established in biopharmaceutical production. However, some developers and producers of biopharmaceuticals refuse their usage because of potential interactions of the plastic material with cells and proteins. Most dreaded apart from extractables are leachables (such as bDtBPP [1]), that derive from additives and are formed during the bag manufacturing process or gamma sterilization. Leachables can migrate from the film contact layer into the process fluid under process conditions and can inhibit cell growth or impair product quality. A further reason for cell growth limitations can be …

We have performed first-principles density functional theory calculations, incorporated with van der Waals interactions, to study CO2 adsorption and diffusion in nanoporous solid – OMS-2 (Octahedral Molecular Sieve). We found the charge, type, and mobility of a cation, accommodated in a porous OMS-2 material for structural stability, can affect not only the OMS-2 structural features but also CO2 sorption performance. This paper targets K+, Na+, and Ba2+ cations. First-principles energetics and electronic structure calculations indicate that Ba2+ has the strongest interaction with the OMS-2 porous surface due to valence electrons donation to …
