Description
Summary:After the tremendous advances over the past two decades, micro‐/nanorobots can effectively convert other forms of energy into propulsion and movement, as well as be navigated to targeted locations under physiological conditions and environments. They have been demonstrated to have the potential to load, transport, and deliver therapeutic payloads directly to disease sites, thereby improving the therapeutic efficacy and reducing systemic side effects of highly toxic drugs. In this feature article, the various propulsion modalities of micro‐/nanorobots ranging from chemical/biochemical reactions to external fields, and to motile microorganisms are summarized and commented in terms of driving forces required by the automotive motion in biological media, biocompatibility, as well as the corresponding advantages and limitations in terms of biomedical applications. Then, the latest developments of in vitro and in vivo active drug delivery based on micro‐/nanorobots are discussed in detail. The challenges and future prospects are also highlighted in the end. With ever booming research enthusiasm in this field and increasing multidisciplinary cooperation, micro‐/nanorobots with intelligence and multifunctions will emerge in the near future, which would have a profound impact on the treatment of diseases. An overview of recent developments of active drug delivery based on micro‐/nanorobots has been presented. With continuous innovation, future micro‐/nanorobots with intelligence and multifunctionality will represent an important modality within diverse biomedical applications, providing unlimited opportunities beyond one's imagination.
