Adaptive hierarchical origami-based metastructures

Nature Communications, Год журнала: 2024, Номер 15(1)

Shape-morphing capabilities are crucial for enabling multifunctionality in both biological and artificial systems. Various strategies shape morphing have been proposed applications metamaterials robotics. However, few of these approaches achieved the ability to seamlessly transform into a multitude volumetric shapes post-fabrication using relatively simple actuation control mechanism. Taking inspiration from thick origami hierarchies nature, we present hierarchical construction method based on polyhedrons create an extensive library compact metastructures. We show that single structure can autonomously adapt over 10

Oral administration microrobots for drug delivery

Bioactive Materials, Год журнала: 2024, Номер 39, С. 163 - 190

Опубликована: Май 21, 2024

Oral administration is the most simple, noninvasive, convenient treatment. With increasing demands on targeted drug delivery, traditional oral treatment now facing some challenges: 1) biologics how to implement and ensure bioavailability not lower than subcutaneous injections; 2) How achieve therapy of drugs in gastrointestinal tract? Based these two issues, delivery microrobots have shown great application prospect due their characteristics flexible locomotion or driven ability. Therefore, this paper summarizes various developed recent years divides them into four categories according different driving modes: magnetic-controlled microrobots, anchored self-propelled biohybrid microrobots. As involve disciplines such as materials science, mechanical engineering, medicine, control systems, begins by introducing barriers that must overcome. Subsequently, it provides an overview typical involved design process To enhance readers' understanding working principles we present a guideline for designing Furthermore, current development status types reviewed, summarizing respective advantages limitations. Finally, considering significant concerns regarding safety clinical translation, discuss challenges prospections translation presented paper, providing corresponding suggestions addressing existing challenges.
