Amine‐Functionalized Chitosan/dECM Composite Promotes Cutaneous Regeneration and Hair Follicle Activation by Regulating Oxidative Stress and Inflammation

Advanced Healthcare Materials, EarlyView.
An amine‐functionalized chitosan and hydrolyzed dECM composite promotes cutaneous regeneration by modulating oxidative stress and inflammatory pathways. The material accelerates wound closure and stimulates hair follicle activation in UV‐damaged cutaneous tissue.

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia

Advanced Healthcare Materials, EarlyView.
This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

Advanced Materials, EarlyView.
This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.

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 ...

Refractive index sensor for sensing high refractive index bioliquids at the THz frequency

Journal of the Optical Society of America B, 2021
In this paper, a highly sensitive and low loss refractive index (RI) biosensor for high RI bio-analytes detection, such as for cholesterol, nicotine, and bacillus bacteria, is proposed. A novel, to the best of our knowledge, decagonal structure with porous core photonic crystal fiber (PC-PCF) is introduced.

Twisted Optical Microfibers for Refractive Index Sensing

IEEE Photonics Technology Letters, 2011
A simple, compact, and robust refractive index sensor is developed, by twisting a pair of silica microfibers to form a coupling device. The transmission spectrum of the device is highly sensitive to the surrounding refractive index and the highest sensitivity obtained is -2377 nm/refractive index unit (RIU), at the refractive index value of - 1.3680 ...
