A Microfluidic Gradient Generator Post‐Modified by Two‐Photon Direct Laser Writing for Dynamic Particle Functionalization

Journal of Applied Polymer Science, Volume 143, Issue 21, June 5, 2026.
We present a Christmas‐tree‐shaped microfluidic gradient generator (MGG) that is equipped with dynamic trapping chambers, based on thermoresponsive microactuators. At room temperature, amine‐functionalized polystyrene beads are trapped inside the pNIPAM funnels and fluorescently labeled.

Investigating Hydrogel Structural Parameters in the Flory–Rehner Model Using Bayesian Optimization

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Hydrogels exhibit tunable solvent absorption driven by environmental stimuli such as temperature, pH, and light. While prior work established connections between synthesis processes and swelling behavior of temperature‐responsive hydrogels, the current study bridges the internal structure and the temperature‐responsive swelling behavior. First,

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

Advanced Materials Technologies, Volume 11, Issue 10, 22 May 2026.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across
