Taxis orientation is common in microorganisms, and it provides feasible strategies to
operate active colloids as small‐scale robots. Collective taxes involve numerous units that …

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 …

The past two decades have seen a remarkable progress in the development of synthetic
colloidal agents which are capable of creating directed motion in an unbiased environment …

Fluid flow is ubiquitous in many environments that form habitats for microorganisms.
Therefore, it is not surprising that both biological and artificial microswimmers show …

Biological microswimmers navigate upstream of an external flow with trajectories ranging
from linear to spiralling and oscillatory. Such a rheotactic response primarily stems from the …

Bacterial contamination of biological channels, catheters or water resources is a major threat
to public health, which can be amplified by the ability of bacteria to swim upstream. The …

The active delivery of drugs to disease sites in response to specific biomarkers is a holy grail
in theranostics. If successful, it would greatly diminish the therapeutic dosage and reduce …

As a novel mobile nanodevice, micro‐nano motors (MNMs) can convert the energy of the
surrounding environment into mechanical motion. With this unique ability, they promise …

Through billions of years of evolution, microorganisms mastered unique swimming
behaviors to thrive in complex fluid environments. Limitations in nanofabrication have thus …

Synthetic chemically powered active matter aims to reproduce many of the salient features of
out-of-equilibrium living systems. These include exhibiting emergent properties and complex …
