Microfluidic devices have shown promising applications in the bioprocessing industry. However, the lack of modularity and high cost of testing and error limit their implementation in the industry. Advances in 3D printing technologies have facilitated the conversion of microfluidic devices from research output to applicable industrial systems. Here, for the first time, we presented a 3D printed modular microfluidic system consisting of two micromixers, one spiral microfluidic separator, and one microfluidic concentrator. We showed that this system can detach and separate mesenchymal stem cells (MSCs) from microcarriers (MCs) in a short time while maintaining the cell’s viability and functionality. The system can be multiplexed and scaled up to process large volumes of the industry. Importantly, this system is a closed system with no human intervention and is promising for current good manufacturing practices.
Graphical Abstract
In article number 2005363, Majid Ebrahimi Warkiani and co‐workers comprehensively review the existing intracellular delivery technologies at the macro‐ and micro‐/nanoscale based on their impact resolution. This study gives an insight to researchers interested in intracellular delivery, ranging from biologists looking for the most appropriate cargo‐delivery method, to cell physiologists seeking a deeper understanding of intracellular delivery and its underlying mechanisms, to biomanufacturing experts eager to boost production efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
