Targeting Cancers with Microrobots and Bacteriobots.

Developing efficient medication delivery systems is a key area of research that will improve the efficacy of cancer treatments. As cancer cells have certain characteristics, it is crucial to precisely deliver chemotherapeutic drugs to the tumor microenvironment without harming healthy tissues. There has been a growing interest in exploiting biological agents to overcome the disadvantages of traditional cancer treatments in targeting and delivering drugs. These technologies utilize specific properties of the tumor microenvironment, such as the availability of excess glucose. This review discusses the current understanding of microrobots for cancer treatment with a special focus on bacteriobots. Bacteriobots are excellent candidates for smart cancer therapy because they can respond to particular cues from the tumor microenvironment. Similarly, microrobots include bacteriobots and other miniature materials/devices for the precise and specific targeting of cancer cells. Here, we discuss synthetic and biohybrid microrobots. It is imperative to make further technological advancements so that they can be employed on a large scale for cancer treatment.
