Smart Sampling Capsule for Capture and Detection of Enteric Pathogens in the Small Intestine

Advanced Materials Technologies, EarlyView.
An ingestible smart sampling capsule for capturing asymptomatic enteric pathogens at their primary sites of interaction within the small intestine. This capability enables non‐invasive detection of early pathogen colonization within the gut environment prior to fecal shedding, providing a robust approach for pathogen surveillance and microbiome studies.

Untethered Magnetic Microswimmers for Targeted Particle Transport and Flow Manipulation

Advanced Materials Technologies, EarlyView.
This work introduces magnetically actuated microswimmers to dynamically reconfigure fluid flow within a single microfluidic device. Multiple homogeneous microswimmers are independently controlled by an external magnetic field to perform translational and rotational motions, thereby inducing real‐time flow manipulation.

Programmable Microscale Actuation of Hydrogels With Tunable Response via Printing on Particles

Advanced Materials Technologies, EarlyView.
We fabricate microscale hydrogels with precisely tunable phase transition temperatures (23–60 °C) by particle‐templated two‐photon polymerization using chemically tailored inks. Multi‐material printing enables stepwise thermal actuation through sequential volume changes at distinct VPTTs, while pH‐dependent hysteresis drives anisotropic actuation with ...
