Method for the preparation of thin-skinned asymmetric reverse osmosis membranes and products thereof [PDF]

open access: yes, 1984
A method for preparing water insoluble asymmetric membranes from water soluble polymers is discussed. The process involves casting a film of the polymer, partially drying it, and then contacting it with a concentrated solution of a transition metal salt.

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

Delivery of Islatravir via High Drug‐Load, Long‐acting Microarray Patches for the Prevention or Treatment of Human Immunodeficiency Virus

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Islatravir‐loaded dissolving microarray patches (MAPs) provide a minimally invasive, long‐acting solution for HIV‐1 prevention and treatment. In rats, sustained islatravir delivery lasts up to three months, while in minipigs, efficacious plasma levels are detected for six days.

Reservoir‐Type Subcutaneous Implantable Devices Containing Porous Rate Controlling Membranes for Sustained Delivery of Risperidone

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a novel implantable drug delivery systemwith a biodegradable poly(caprolactone) membrane and compressed drug core forsustained release. These implantable devices deliver risperidone in vitro for 170 days and in vivo for 49 days in rats, showing promise for chronic conditions like schizophrenia.

Dexamethasone Delivery via Amphiphilic, Low‐swelling Hydrogels Treats Postoperative Inflammation in Cervical Spine Applications

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
DexaPatch, an implantable, low‐swelling amphiphilic hydrogel system containing dexamethasone‐PLGA microparticles, is developed and characterized for sustained local steroid release to reduce postoperative inflammation in tight surgical spaces. DexaPatch significantly reduces postoperative edema and fibrosis in a rabbit model of anterior spinal surgery,

3D Bioprinting‐Assisted Engineering of Stem Cell‐Laden Hybrid Biopatches With Distinct Geometric Patterns Considering the Mechanical Characteristics of Regular and Irregular Connective Tissues

open access: yesAdvanced Healthcare Materials, EarlyView.
A hybrid biopatch platform integrating 3D printed polymeric patterns with stem cell‐laden collagen bioinks is developed to mimic the mechanical properties of connective tissues. By tailoring geometric architectures, the constructs replicate anisotropic or isotropic mechanics, enhancing tissue‐specific regeneration.
