A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

open access: yesAdvanced Healthcare Materials, EarlyView.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.

Electromechanical wavelength tuning of double-membrane photonic crystal cavities [PDF]

open access: yes, 2011
We present a method for tuning the resonant wavelength of photonic crystal cavities (PCCs) around 1.55 um. Large tuning of the PCC mode is enabled by electromechanically controlling the separation between two parallel InGaAsP membranes.

A Synovium‐on‐Chip Platform to Study Multicellular Interactions in Arthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
The Synovium‐on‐Chip comprises a thin microporous PDMS membrane to support co‐culture of fibroblast‐like synoviocytes (FLS), THP‐1‐derived macrophages, and endothelial cells, enabling real‐time analysis of synovial‐vascular interactions. FLS migration through the pores drives endothelial remodeling, while TNF‐α stimulation induces robust inflammatory ...

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Experimental Study of Plasma Actuator Effects on Flow Field Separation Bubble around Blunt Flat Plate

open access: yesJournal of Applied Fluid Mechanics, 2016
In this paper, the air flow around a blunt flat plate with a rounded leading edge has been experimentally examined with and without the presence of a plasma actuator. Tests have been conducted with Reynolds numbers ranging from 104 to 105.

Temporally Delayed Deployment of Photo‐Responsive Liquid Crystal Polymer Networks Toward Neural Interfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
Deployable medical devices typically need external stimuli to trigger deployment. However, external stimuli are difficult to supply within tissues. Here, we describe a strategy to deploy small‐scale structures into soft tissues after insertion without the need for any stimulus. We demonstrate deployment within a tissue phantom.
