A 3D Printing Strategy for Hard Curved Surfaced Circuits: From Materials to Applications

open access: yesAdvanced Science, EarlyView.
Conventional PCB etching (multi‐step) and indirect transfer techniques fail to meet structural electronics’ demands for lightweight, miniaturized, and customized manufacturing. 3D‐printed conformal circuits enable direct integration of conductive traces into substrates or onto surfaces, achieving integrated structural‐functional fabrication.

Bionic Microneedle Patch Inspired by Drosophila Tarsal Paws Boosts Healing in Bacterial Infectious Stomatitis

open access: yesAdvanced Science, EarlyView.
Microneedle suction cup patches, prepared using bionic Drosophila tarsal claws, can effectively treat bacterial infectious stomatitis by rapidly and efficiently leveraging multiple effects, including antibacterial and anti‐inflammatory properties, promotion of vasodilation, and active mechanical contraction of the wound.

Gut Metabolite Indole‐3‐Propionic Acid Regulates Macrophage Autophagy Through PPT1 Inhibiting Aging‐Related Myocardial Fibrosis

open access: yesAdvanced Science, EarlyView.
IPA is an intestinal tryptophan metabolite whose effects decline with decreased heart function. Supplementing IPA can alleviate the aging‐related myocardial fibrosis through PPT1. PPT1 is a key protein localized to lysosomes, and IPA can restore macrophage autophagy function by regulating PPT1 expresssions, thereby reducing aging‐related myocardial ...

ε‐Poly‐L‐lysine‐graft‐oligo(3‐hexylthiophene) Copolymers as Antibacterial and Biodegradable Polymer Electronics

open access: yesAdvanced Science, EarlyView.
ε‐Poly‐L‐lysine‐graft‐oligo(3‐hexylthiophene) (EPL‐g‐O3HT) copolymers are engineered as biodegradable and antibacterial materials for transient electronics. EPL‐g‐O3HT exhibits tunable conductivity, controlled enzymatic degradability, good biocompatibility, and potent antibacterial activity. They are demonstrated in electromyography sensors and organic
