“…Changes in swimming are even predicted at low obstacle volume fractions. Leshansky showed that the presence of stationary obstacles in the fluid increases the swimming speed and efficiency of a helical filament with a fixed rotation rate or even with fixed power input (Figure 2b), essentially by pushing off of the surrounding obstacles (through the fluid) (25,29). Experiments with C. elegans showed too an enhanced mobility in such environments due to an increase in tangential/normal drag anisotropy (Figure 2c) (26).…”

We review the literature on swimming in complex fluids. A classification is proposed by comparing the length and time scales of a swimmer with those of nearby obstacles, interpreted broadly, extending from rigid or soft confining boundaries to molecules which confer the bulk fluid with complex stresses. A third dimension in the classification is the concentration of swimmers, which incorporates fluids whose complexity arises purely by the collective motion of swimming organisms. For each of the eight system classes which we identify we provide a background and describe modern research findings. While some classes have seen a great deal of attention for decades, others remain uncharted waters still open and awaiting exploration.

“…In this respect, several microrobots have been proposed to offer high resolution maneuverability in complex environments. ,,− While this problem is interesting from a fundamental perspective and will enable future studies on directing the motions of multiple microrobots, single microparticle maneuverability in a complex physiological environment is not applicable to most biomedical tasks. Applications such as medical catheterization, stent placement, and clot clearance do require precise single particle manipulation; , however, many proposed applications such as remote biopsy, surgery, and sensing are likely infeasible given the current capabilities of microrobots, meaning that a focus on such applications will only hinder clinical translatability.…”

Microrobots are being explored for biomedical applications, such as drug delivery, biological cargo transport, and minimally invasive surgery. However, current efforts largely focus on proof-of-concept studies with nontranslatable materials through a "design-and-apply" approach, limiting the potential for clinical adaptation. While these proof-of-concept studies have been key to advancing microrobot technologies, we believe that the distinguishing capabilities of microrobots will be most readily brought to patient bedsides through a "design-by-problem" approach, which involves focusing on unsolved problems to inform the design of microrobots with practical capabilities. As outlined below, we propose that the clinical translation of microrobots will be accelerated by a judicious choice of target applications, improved delivery considerations, and the rational selection of translation-ready biomaterials, ultimately reducing patient burden and enhancing the efficacy of therapeutic drugs for difficult-to-treat diseases.
