Abstract

Buffer exchange is a common process in manufacturing protocols for a wide range of bioprocessing applications, with a variety of technologies available to manipulate biological materials for culture medium exchange, cell washing and buffer removal. Microfluidics is an emerging field for buffer exchange and has shown promising results with both prototype research and commercialised devices which are inexpensive, highly customisable and often have the capacity for scalability to substantially increase throughput. Microfluidic devices are capable of processing biological materials and exchanging solutions without the need for conventional processing techniques like centrifugation, which are time-consuming, unsuitable for large volumes and may be damaging to cells. The use of microfluidic separation devices for cell therapy manufacturing has been under-explored despite some device designs successfully being used for diagnostic enrichment of rare circulating tumour cells from peripheral blood. This mini-review aims to review the current state of microfluidic devices for buffer exchange, provide an insight into the advantages microfluidics offers for buffer exchange and identify future developments key to exploiting the technology for this application.
