Article Abstract
Current myocardial infarction (MI) treatment strategies remain challenged in suboptimal pharmacokinetics and potential adverse effects. Here we present a bioelectronic interface capable of producing on-demand abundant bioactive extracellular vesicles (EVs) near the MI area for in-situ localized treatment. The technology, termed electroactive patch for wirelessly and controllable EV generation (ePOWER), leverages wireless bioelectronic patch to stimulate embedded electrosensitive macrophages, actively modulating the biosynthesis of EVs and enabling EV production with high programmability to be delivered directly to the MI area. ~2400% more bioactive EVs were produced per cell under our ePOWER system. When surgically implanted, we demonstrate the therapeutic potential of in-situ EV production system to alleviate MI symptoms and improve cardiac function. This programmable ePOWER technology enables in-situ production of therapeutically rich EVs, thus reducing the need for exogenous cell expansion platforms and dedicated delivery, holding promise as a therapeutic all-in-one platform to treat various diseases.

Infected wounds remain a major clinical challenge due to bacterial invasion, which disrupts the natural healing cascade through excessive reactive oxygen species (ROS) generation, severe vascular damage, and persistent inflammation. Inspired by the catechol-rich adhesive domains of mussel foot proteins, we developed an extracellular matrix (ECM)-mimetic polyethylene glycol (PEG) hydrogel incorporating polydopamine (PDA)-functionalized zinc oxide nanoparticles (ZnONPs) for infected wound therapy. The amino acid-functionalized PEG hydrogel reproduces ECM-like properties to facilitate cell migration and efficient exudate management; however, its lack of intrinsic antimicrobial activity limits therapeutic efficacy.

Nano-sized extracellular vesicles (EVs) possess a lipid bilayer and are secreted from cells into their surrounding environment. The transport of multiple biomolecules, including DNA together with RNA, microRNAs (miRNAs), lipids, proteins, and metabolites, happens through biofluids via EVs for intercellular communication. Extracellular vesicles play crucial roles during the embryo production (IVEP) process.

Heart failure (HF) is a global public health challenge closely associated with oxidative stress and immune dysregulation. However, current therapeutic strategies for HF generally lack specific targeting to cardiac tissue, and the high perfusion rate of the heart further exacerbates insufficient drug accumulation at lesion sites, thus compromising therapeutic efficacy. Inspired by the barb-hook of Xanthium strumarium, FeO@UiO-66 is functionalized with tannic acid (TA) to obtain a dual-target nanocatalyst, termed FUTA.

Extracellular vesicles (EVs) are heterogeneous populations of membrane-bound particles released from almost all cell types in an organism and play pivotal roles in cell-cell communication. EVs carry nucleic acids, proteins, metabolites and other bioactive substances, which are taken by the recipient cells to alter cell physiology and functions. The cargo landscapes of EVs are influenced by the cell contexts and the biogenesis mechanisms of EVs, in which certain molecules govern both biogenesis and cargo sorting.

Large, complex wounds frequently exhibit suboptimal healing, leading to scarring and functional impairment. While bioactive materials and electrical stimulation (ES) show promise, their individual limitations call for novel approaches. This study investigates the combined effects of combining 4-aminopyridine (4AP) and electrical stimulation (ES) on human dermal fibroblasts (hDFBs) using a stable, ionically conductive (IC) chitosan-based scaffold for controlled drug delivery.
