Core Viewpoint - The article discusses a significant breakthrough in drug delivery technology, specifically through the development of a flexible, implantable bioelectronic device called POCKET, which allows for precise and efficient drug delivery to complex organ surfaces, addressing long-standing issues in traditional drug delivery methods [2][3]. Research Background - The research originated from a clinical challenge faced by doctors regarding hereditary ovarian gene mutations, where traditional gene therapy methods pose risks to reproductive cells. The team shifted focus to a physical method called electroporation to deliver therapeutic agents safely to ovarian surface cells without affecting the eggs [7]. Breakthrough Innovation - The research team drew inspiration from traditional paper-cutting art to create a "customized organ conformal kirigami theory," establishing a quantitative relationship between geometric parameters of the kirigami structure and the curvature of organs, enabling the design of patches that achieve over 95% coverage on organ surfaces [9]. Device Design and Functionality - The POCKET device features a four-layer functional design, including a nanopore array film for direct tissue contact, a hydrogel drug-loading layer, a silver nanowire electrode layer for electric field distribution, and a flexible substrate layer. This design allows for high conformability and large-area adhesion to various organ surfaces [12]. Efficacy Validation 1: Ovarian Cancer Prevention - In animal models, POCKET successfully delivered functional BRCA1 plasmids to ovarian surface cells, significantly reducing cancer risk without affecting reproductive cells. This approach restored ovarian hormone secretion and fertility, providing a viable alternative to surgical removal for women with cancer risk mutations [15]. Efficacy Validation 2: Organ Damage Repair - In kidney transplant scenarios, POCKET was used to deliver anti-inflammatory drugs locally, showing significant improvement in tubular repair and kidney function while avoiding systemic side effects associated with oral medications, highlighting its advantages in chronic disease management [19]. Technology Translation and Clinical Application - The POCKET platform offers new tools for precise treatment of ovarian cancer prevention and organ damage repair, integrating flexible electronics and micro-nano processing for effective control and long-term operation. The technology has progressed from laboratory to industry, with a high-tech company already established and the first product, Ultra-NEP, applied in skin health [22][24].

Core Viewpoint - The research teams from Tsinghua University and Capital Medical University have developed a novel method to bypass the blood-brain barrier using nanoparticles to deliver drugs directly to stroke lesions, potentially overcoming a significant challenge in neurological disease treatment [1][3]. Group 1: Research Findings - The study reveals that the bone marrow within the skull is not a static structure but is connected to the meninges through microchannels, allowing immune cells to bypass the blood-brain barrier and enter the brain [3]. - The research team utilized a minimally invasive injection method to deliver albumin nanoparticles into the skull bone marrow, which were efficiently taken up by immune cells, forming "skull immune cell micro-nanobots" for targeted drug delivery [3][4]. - The nanoparticles demonstrated low systemic exposure, with minimal entry into peripheral blood and major organs, ensuring good biocompatibility and safety [3][4]. Group 2: Clinical Implications - In mouse models of acute ischemic stroke, the new delivery method significantly reduced infarct volume and edema, improved neurological function, and showed long-term benefits in reducing brain atrophy and enhancing survival rates [4]. - An exploratory clinical study involving 20 patients with malignant cerebral artery occlusion indicated that the procedure was well-tolerated, with no severe adverse events reported, and showed positive trends in neurological recovery [4][5]. Group 3: Future Prospects - The research suggests that this delivery pathway could extend beyond drug delivery, potentially integrating with brain-machine interface technologies to facilitate multi-directional exchanges of materials, energy, and information between the brain and artificial systems [5].

Core Viewpoint - The research highlights the superior potential of small intracellular vesicles (sIV) over small extracellular vesicles (sEV) in drug delivery and retinal neuroprotection, suggesting a promising avenue for clinical applications in biomedical engineering [3][9][12]. Group 1: Research Findings - The study developed a method for isolating sIV from various cell types and demonstrated that sIV outperforms sEV in uptake, drug delivery, and retinal neuroprotection [3][7]. - sIV are smaller in size and yield higher quantities compared to sEV, exhibiting stronger cellular uptake capabilities in both in vitro and in vivo models [9]. - Molecular analysis revealed that sIV are enriched with endoplasmic reticulum and Golgi apparatus-related proteins, possessing unique microRNA characteristics associated with the intracellular membrane system, and contain higher levels of phospholipids such as phosphatidylcholine and phosphatidylethanolamine [9]. Group 2: Therapeutic Applications - sIV derived from mesenchymal stem cells (MSC) showed remarkable therapeutic effects in a retinal degeneration model by alleviating endoplasmic reticulum stress and delivering neuroprotective factors [9][11]. - The enhanced drug loading and delivery capabilities of sIV allow for effective transport of lipophilic compounds, such as rapamycin, to the retina [11]. Group 3: Implications for Clinical Translation - The findings indicate that sIV could serve as a promising alternative to traditional biological nanovesicles in clinical translation, potentially overcoming the limitations faced by sEV in therapeutic applications [12].
