Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes

open access: yesAdvanced Materials Technologies, EarlyView.
This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...

Cardiovascular effects of iodinated contrast agents

open access: yesThe American Journal of Cardiology, 1990
The ideal intravascular contrast agent would be biologically inert and have no pharmacologic actions. Pharmacologic actions of currently used radiographic contrast agents are determined principally by 3 physicochemical properties of the iodine-bearing molecule and its formulation: osmolality, sodium concentration and calcium-binding properties.
