Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

open access: yesAdvanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

open access: yesAdvanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

Polyesters and Polyester Nano- and Microcarriers for Drug Delivery

open access: yesPolymers
Many therapies require the transport of therapeutic compounds or substances encapsulated in carriers that reduce or, if possible, eliminate their direct contact with healthy tissue and components of the immune system, which may react to them as something foreign and dangerous to the patient’s body.

Concept of Recycling‐on‐Demand Investigated on Linear Poly(Ester‐Co‐Acetal)s

open access: yesMacromolecular Materials and Engineering
Effective recycling of polymers into valuable resources is the basis for establishing a circular economy. Whereas mechanical recycling often leads to downcycling, the concept of recycling‐on‐demand (ROD) has high promise.
