Abstract

The economic and ecological importance of microorganisms and their fundamental functions in different contexts is well-documented. They constitute the major part of the world's biomass, represent the lowest level of the food chain [1] and are utilised in a wide range of applications that encompass food and beverage preparation, genetic engineering and renewable energy. [2, 3] Some microorganisms can swim and propel themselves and are termed as microswimmers; the definition includes bacteria, spermatozoa, unicellular, colonial algae and protozoans. [1] This work focuses on the fluid dynamic behaviour of Dunaliella Salina (DS) (a type of halophile green micro-algae found in hypersaline environments) in microfluidic contraction-expansion geometries for varying flow conditions, in order to engineer the motion of the cells and enhance the efficiency of their applications.
