Manipulating Liquid‐Liquid Interphase Solute Diffusion for the Construction of Non‐Symmetric Metal‐Quinone Network Nanoarchitectonics and Nano‐Motorization

open access: yesAdvanced Science, EarlyView.
Non‐symmetric metal‐quinone network (MQN) nanoarchitectonics with controllable morphology and size are constructed by manipulating interphase solute diffusion during the nanoprecipitation process. Self‐propelled nanomotors developed from non‐symmetric MQN nanoarchitectonics exhibit chemotactic autonomous motion toward overexpressed H2O2 in tumor ...

Oscillating Magnetic Field Induced Bone Injury Repair by using Drug‐Free Micromotors

open access: yesAdvanced Science, EarlyView.
This work presents a payload‐free, minimally invasive approach for bone repair using magnetic hydrogel micromotors, which enhance bone regeneration via localized micromovement stimulation, achieving a twofold increase in new bone formation in vivo. Abstract Bone injury repair remains a significant clinical challenge due to the tissue's limited self ...

Magnetite Micro/Nanorobots for Efficient Targeted Alleviation of Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
Improved reactive oxygen species scavenging capacities of functionalized micro/nanorobots (MNRs) are useful for the treatment of inflammatory bowel disease (IBD). MNRs can break the harmful bacteria in IBD, thereby eliminating inflammation and restoring the intestinal barrier function.

Mechanotransduction Activates Microglia and Impairs Phagocytosis in Stiff Amyloid‐β Plaques

open access: yesAdvanced Science, EarlyView.
The study constructs an in vitro Aβ plaque‐associated microglia model and uses SECM and SICM to in situ monitor changes in ROS levels, membrane permeability, and phagocytosis of microglia during Aβ clearance. It is found out that Aβ stiffness triggers microglial activation via the PIEZO1 mechanotransduction pathway, causing neuroinflammation and ...

Electrochemical‐Genetic Programming of Protein‐Based Magnetic Soft Robots for Active Drug Delivery

open access: yesAdvanced Science, EarlyView.
This manuscript presents a protein‐based soft robot for active drug delivery. Stimuli‐responsive protein is rationally designed and processed into the substrate of robots. Superparamagnetic Fe3O4 nanoparticles are patterned on the substrate using an electrochemical method, enabling the robot to respond to external physical fields.
