Impact of Dean Vortices on the Integrity Testing of a Continuous Viral Inactivation Reactor [PDF]
Biotechnology Journal, 2018 We propose a standard protocol for integrity testing the residence‐time distribution (RTD) in a “Jig in a Box” design (JIB)—a previously described tortuous‐path, tubular, low‐pH, continuous viral inactivation reactor, ensuring that biopharmaceutical products will be incubated for the required minimum residence time, tmin .

Advanced Science, EarlyView.A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.
