Tunable Enhancement of T Cell Expansion Through Modulation of Stiffness and Adhesion Receptor Engagement in an Engineered Hydrogel Platform

Advanced Materials, EarlyView.
We develop a hydrogel scaffold with controlled substrate stiffness and ligand functionalization for cell culture. Stiff substrates presenting CD3/CD28/CD2 ligands induce 2000‐fold expansion of T cells; this is 68% greater than the clinical standard (Dynabeads) and the first hydrogel capable of large‐scale expansion. Although expanding at a lower yield,

A Reconfigurable Crawling Robot Driven by Electroactive Artificial Muscle

International Conference on Soft Robotics, 2019
In nature, inchworms can move freely on uneven terrains where conventional wheeled or tracked robots cannot. Emerging soft actuation technologies such as dielectric elastomer actuators (DEAs) offer a new approach for inchworm-inspired robot designs ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Ligand-specific binding forces of LFA-1 and Mac-1 in neutrophil adhesion and crawling

Molecular Biology of the Cell, 2017
The force spectra for various LFA-1/Mac-1–ligand bonds were compared and their functions tested in mediating PMN recruitment under flow. Multiple endothelial ligands present distinct bond rupture forces and lifetimes, which correlate well with their ...

Multifunctional Fluidic Units for Emergent, Responsive Robotic Behaviors

Advanced Materials, EarlyView.
A multifunctional reconfigurable fluidic unit can be used as sensor, valve and actuator is presented. A unique configuration combines the features of the three components as a Responsive self‐oscillating actuator. The remarkable versatility of the fluidic unit is demonstrated by building different robots with the same fluidic units only by varying ...

Crawling EDGAR

The Spanish Review of Financial Economics, 2012
While our kids may think this paper is about spiders, it is, unfortunately, about rms in the United States reporting relevant business information to the Securities and Exchange Commission (SEC). The paper is meant to serve as a primer for economists in the computing details of searching for information in the Internet.

Crawling-induced floor dust resuspension affects the microbiota of the infant breathing zone

Microbiome, 2018
Floor dust is commonly used for microbial determinations in epidemiological studies to estimate early-life indoor microbial exposures. Resuspension of floor dust and its impact on infant microbial exposure is, however, little explored.

Review of Thin Lithium Metal Battery Anode Fabrication – Microstructure – Electrochemistry Relations

Advanced Materials, EarlyView.
Thin, lightweight lithium‐metal anodes are pivotal for practical high‐energy batteries. This review surveys processing routes that convert diverse Li precursors, e.g., ingots, melts, solutions, and vapor, into Li‐rich foils with controlled thickness, areal density, and tailored functionality.

Emergent Motility of Self‐Organized Particle‐Giant Unilamellar Vesicle Assembly

Advanced Materials, EarlyView.
Giant unilamellar vesicles (GUVs), when combined with silica particles under alternating electric fields, spontaneously self‐assemble into motile structures. Asymmetric particle decoration induces fluid flows that propel the assemblies, enabling persistent motion and reversible control.
