Covalent Binding of Dexamethasone to Polyimide Improves Biocompatibility of Neural Implantable Devices

open access: yesAdvanced Healthcare Materials, EarlyView.
The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.

Training to meet the need for refractive error services

open access: yesCommunity Eye Health Journal, 2007
In many low- and middle-income countries, there are inadequate refractive error services for the many people who are currently either blind or visually impaired because they lack a pair of spectacles.The prioritisation of refractive error and low vision ...

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Investigation on the Influence of Protein Corona and Platelet Adhesion on Storage Bag Surface on the Platelet Storage Lesion

open access: yesAdvanced Healthcare Materials, EarlyView.
Platelet quality deteriorates during storage due to protein and platelet adhesion to current bag materials. Here, polymer coatings are identified that reduce adhesion and translated them to mini‐storage bags. Platelet quality are not impacted, despite significantly reducing adhesion.

Human Skin Models in Biophotonics: Materials, Methods, and Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
This review discusses how the optical properties of human skin can be replicated in human skin models. It describes the principles, materials, and techniques used to develop artificial skin for biophotonics research. Finally, the article highlights recent advances and shows how these models improve the study of light‐skin interactions without the need ...
