Background Drug delivery systems (DDSs) encompass a wide range of methods, including oral, injectable, and topical routes of administration, all tailored to meet specific patient needs. Micro and nanorobots, equipped with pioneering propulsion mechanisms that convert external energy sources into precise movements, have revolutionized drug delivery. This cutting-edge technology ensures highly efficient drug delivery, particularly when targeting specific targets within intricate physiological environments. In contrast to traditional drug delivery approaches that rely on bloodstream circulation, engineered micro/nanorobots have autonomous mobility, enabling drug delivery to previously unreachable areas. Main body of the abstract Integrating micro/nanorobots into drug delivery raises vital safety and biocompatibility issues. These encompass material selection, degradation in-vivo, overcoming biological barriers, controlled movement, external interference, immune response, chemical reactions, systemic effects, long-term impact, and real-time monitoring. While micro/nanorobots hold immense transformative potential, they confront significant hurdles in their journey toward practical applications. Chief among these challenges are concerns regarding biocompatibility, ensuring that these tiny devices do not trigger adverse reactions. Long-term safety remains a critical issue, as understanding the effects of prolonged exposure and potential accumulations within the body and navigating complex biological environments with precision is another obstacle. Short conclusion The paper summarizes how to explore the various ways in which micro/nanorobots can be employed to enhance drug delivery, including their precision, targeting capabilities, and adaptability to different physiological conditions. Additionally, the review seeks to highlight the transformative potential of these technologies and their impact on the pharmaceutical industry.

“…The degree of alignment and corresponding swelling anisotropy can be effectively modulated primarily by adjusting the nozzle diameter and print. 64,67,75 Smaller nozzle diameters, for instance, lead to more pronounced alignment as shear forces inversely scale with nozzle diameter. However, the adoption of smaller nozzle diameters may be constrained by the rheological properties of the ink.…”

“…Creating smart materials using laser processing and shape change manipulation is a modern approach that involves using laser irradiation to induce controlled changes in the shape and dimensions of a material. It is particularly useful for developing materials with shape memory properties, making it suitable for 4D processes, such as the creation of objects that can change their shape in response to various cues [135][136][137]. 4D printing is an emerging technology that extends the concept of 3D printing by adding an additional dimension-time.…”
