Untethered small-scale machines (USSMs) that can actively adjust their motion,
deformation, and collective states in response to external stimuli have gained enormous …

Fluid manipulation plays an important role in biomedical applications such as biochemical
assays, medical diagnostics, and drug development. Programmable fluidic manipulation at …

The bottom‐up construction of a synthetic cell from nonliving building blocks capable of
mimicking cellular properties and behaviors helps to understand the particular biophysical …

Magnetic cell separation has become a key methodology for the isolation of target cell
populations from biological suspensions, covering a wide spectrum of applications from …

Manipulation of micro-and nano-objects has been widely studied in the past two decades
due to its potential applications in various fields. In this review, we focus primarily on …

Tissue engineering raised a high requirement to control cell distribution in defined materials
and structures. In “ink”-based bioprintings, such as 3D printing and photolithography, cells …

Cell spheroids (esp. organoids) as 3D culture platforms are popular models for representing
cell–cell and cell–extracellular matrix (ECM) interactions, bridging the gap between 2D cell …

In nature, cells self-assemble into spatially coded tissular configurations to execute higher-
order biological functions as a collective. This mechanism has stimulated the recent trend in …

Manipulation of micro-objects have been playing an essential role in biochemical analysis
or clinical diagnostics. Among the diverse technologies for micromanipulation, acoustic …

All matter has density. The recorded uses of density to characterize matter date back to as
early as ca. 250 BC, when Archimedes was believed to have solved “The Puzzle of The …
