4D–Printed Photothermally Actuated Soft Microgripper on an Optical Fiber Tip for Biomedical Applications

Advanced Materials Technologies, EarlyView.
In this study, we developed a light–driven soft microgripper by 3D–printing a photo–crosslinkable, temperature–responsive hydrogel with embedded silver particles onto an optical fiber tip. The microgripper actuates via photothermal effects at cell culture temperature and can gently grasp spheroids without minimal damage, offering a compact, actuator ...

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

Role of residual kidney function and convective volume on change in β2-microglobulin levels in hemodiafiltration patients

, 2010
Background and objectives: Removal of β2-microglobulin (β2M) can be increased by adding convective transport to hemodialysis (HD). The aim of this study was to investigate the change in β2M levels after 6-mo treatment with hemodiafiltration (HDF) and to ...

Wireless Precise Manipulation of Tumor Spheroids Using a Millirobot Controlled by Permanent Magnetic Traps

Advanced Robotics Research, EarlyView.
A magnetic donut‐like millirobot is developed for label‐free pick‐and‐place of a tumor spheroid wirelessly controlled by a magnetic trap. Spheroids are important 3D multicellular culture systems that recapitulate key structural and functional features of native tissues.
