Erectile dysfunction (ED) is a major threat to male fertility and quality of life, mesenchymal stromal cells (MSCs) are promising therapeutic option. However, outcomes compromised by low MSC retention survival rates in corpus cavernosum tissue. Here, we developed an innovative magnetic soft microrobot comprising ultrasoft hydrogel microsphere embedded with nanoparticle chain for delivery. This design also features phenylboronic acid groups scavenging reactive oxygen species (ROS). With Young’s modulus less than 1 kPa, the adapts its shape within narrow blood vessels, ensuring uniform distribution MSCs cavernosum. Our findings showed that compared traditional injections, delivery (MSC-Rob) significantly enhanced survival. In both rat beagle ED models, MSC-Rob treatment accelerated repair tissue restored erectile function. Single-cell RNA sequencing (scRNA-seq) revealed facilitates nerve vessel regeneration increasing presence regenerative macrophages. Overall, our not only advances clinical application therapy but broadens scope microrobots other cell therapies.

The advent of autonomous nanomotors presents exciting opportunities for nanodrug delivery. However, significant potential remains enhancing the asymmetry and advancing development second near-infrared (NIR-II) light-propelled capable operating within deep tissues. Herein, we developed a dual-ligand assisted anisotropic assembly strategy that enables precise regulation interfacial energy between selenium (Se) nanoparticle periodic mesoporous organosilica (PMO). This facilitates controllable growth PMO on Se nanoparticle, leading to formation Se&PMO Janus nanohybrids. exposure ratio subunit nanohybrids can be finely tuned from 0% 75%. Leveraging transformability subunit, variety functional MxSe&PMO nanocomposites (MxSe denotes metal selenide) were further derived. As proof concept, CuSe&PMO nanohybrids, with NIR-II photothermal properties, employed as light-driven nanomotors. By precisely controlling CuSe nanostructure, these achieved optimal self-propulsion, thus cellular uptake promoting tumor penetration. Furthermore, high loading capacity hydrophobic framework enabled incorporation disulfiram, thereby significantly boosting efficacy synergistic active-motion therapy.
