One‐Step Tunable Human Hair Keratin Gradient Hydrogel with Antibacterial Activity for Tissue Engineering

open access: yesSmall, EarlyView.
A gradient hydrogel made from human hair extracted keratins is formed via a diffusion‐mediated silver‐thiolate complexation process, driven by keratin's naturally occurring high cysteine content. This single‐step platform offers tunable gradient hydrogel properties, antibacterial activity, and supports extracellular matrix production in vitro. Enhanced

Hydrostatic Pressure Induces Osteogenic Differentiation of Single Stem Cells in 3D Viscoelastic Microgels

open access: yesSmall Science, EarlyView.
Single mesenchymal stem cells are encapsulated in arginine‐glycine‐aspartic acid‐functionalized alginate microgels using a microfluidic chip. After secondary crosslinking, cells are cultured under cyclic hydrostatic pressure in a custom pressurization setup.

A Facile Platform for One‐Step Generation of Uniform Microdroplets through Dehydration‐Driven Phase Separation in Microfluidics

open access: yesSmall Methods, EarlyView.
This study introduces a novel droplet generation method that exploits the intrinsic water absorption of polydimethylsiloxane (PDMS) microchannels. A homogeneous polyethylene glycol/dextran mixture is gradually dehydrated, leading to phase separation and the formation of uniform DEX‐rich droplets.

Combining Nanoscale Curvature and Polymer Osmotic Pressure for Efficient Giant Vesicle Assembly Under Physiological Conditions

open access: yesSmall Methods, EarlyView.
Polymer‐coated nanocellulose paper (PCP) combines nanoscale curvature and polymer osmotic pressure to promote high‐yield giant vesicle assembly under physiological conditions. PCP‐assisted hydration is scalable, compatible with diverse polymers and biochemical encapsulants, and enables robust GUV formation from small to large substrates across a wide ...
