Reactivity‐Guided Janus Graphene With Asymmetric Interfacial Electrostatics for Tunable Charge Transport

Advanced Materials, EarlyView.
Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.

Laser Speckle Contrast Imaging of Hepatic Microcirculation

Biomedical Optics Express
Abstract The liver controls blood homeostasis and depends critically on adequate blood supply. While the global regulation of liver blood flow via the hepatic arterial buffer response is well established, the mechanisms governing hepatic sinusoidal hemodynamics remain elusive.

Light-Sheet Laser Speckle Imaging

, 2022
Abstract Laser speckle imaging (LSI) as a label-free flow mapping technique has numerous potential clinical applications and plays an increasingly important role in translational medicine. Conventional LSI, however, is limited to qualitative flow change assessment and two-dimensional topographic imaging.

Mechanoactive Biomaterials for Cell–Matrix Mechanotransduction

Advanced Materials, EarlyView.
The graphical abstract shows how individual triggers (force, light, or temperature) and combined optothermal or receptor‐targeted actuation induce material responses at the tissue, cellular, and receptor scales. Their spatial (global or focused) and temporal (continuous or cyclic) modulation determines the resulting mechanical output.

Harnessing speckle for a sub-femtometre resolved broadband wavemeter and laser stabilization

Nature Communications, 2017
The complex speckle pattern produced by coherent multiple scattering contains information about the incident light field, which has recently been used for imaging. Metzgeret al. use speckle to construct a wavemeter with sub-femtometre resolution which is

Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

Advanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.
