Direct Ink Writing of Conductive Hydrogels
Advanced Functional Materials, EarlyView.This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

Quantification of depletion-induced adhesion of Red Blood Cells [PDF]
, 2012 Red blood cells (RBC) are known to form aggregates in the forms of rouleaux due to the presence of plasma proteins under physiological conditions. Rouleaux formation can be also induced in vitro by the addition of macromolecules to the RBC solution. Current data on the adhesion strength between red blood cells in their natural discocyte shapes mostly ...

Advanced Functional Materials, EarlyView.On‐cell covalent crosslinking of hydrogel matrix to the membrane of a single cell using droplet microfluidics enables mechanotransduction and influences stem cell fate. This newly established approach influences stem cell fate, independent of YAP/TAZ mechanotransduction and non‐covalent reversible binding ligands yet by various intracellular ...

Colloids Yes or No? - a “Gretchen Question” Answered
Frontiers in Veterinary Science, 2021 Colloid solutions, both natural and synthetic, had been widely accepted as having superior volume expanding effects than crystalloids. Synthetic colloid solutions were previously considered at least as effective as natural colloids, as well as being ...

Effects of dextran and dextran sulfate on the glucoamylase-catalyzed reaction.
Agricultural and Biological Chemistry, 1977 The hydrolysis of maltose by glucoamylase (EC 3. 2. 1. 3 from Rhizopus niveus) was carried out in the presence and absence of dextran and dextran sulfate, which are the components of supports of immobilized enzymes. The interaction between dextran and the enzyme was observed by the fluorescence spectrophotometry.

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment
Advanced Functional Materials, EarlyView.H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...
