Smart soft materials are envisioned to be the building blocks of the next generation of
advanced devices and digitally augmented technologies. In this context, liquid crystals (LCs) …

Bacteria are among the oldest and most abundant species on Earth. Bacteria successfully
colonize diverse habitats and play a significant role in the oxygen, carbon, and nitrogen …

Liquid crystals (LCs) are ubiquitous in display technologies. The orientational ordering in the
nematic phase of LCs gives rise to structural anisotropy, the ability to form topological …

We review the literature on swimming in complex fluids. A classification is proposed by
comparing the length-and timescales of a swimmer with those of nearby obstacles …

Colloids are abundant in nature, science, and technology, with examples ranging from milk
to quantum dots and the colloidal atom paradigm. Similarly, liquid crystal ordering is …

We review recent work on active colloids or swimmers, such as self-propelled
microorganisms, phoretic colloidal particles, and artificial micro-robotic systems, moving in …

There has been a significant interest in the development of microswimmers for medical drug
and cargo delivery, but the majority of current micromotors rely on toxic fuel sources and …

Active matter exhibits remarkable collective behaviour in which flows, continuously
generated by active particles, are intertwined with the orientational order of these particles …

Micro/nano‐robots are powerful tools for biomedical applications and are applied in disease
diagnosis, tumor imaging, drug delivery, and targeted therapy. Among the various types of …

Active colloids in liquid crystals (ACLCs) are an active matter with qualitatively new facets of
behavior as compared to active matter that becomes isotropic when relaxed into an …
