Applications of Nanorobots in Targeted Therapy for Cancer

Nanorobots have broad application prospects in the field of targeted cancer therapy. First, this paper summarizes the basic concepts of nanorobots, classifies and introduces their diverse species, and then summarizes the unique characteristics of nanorobots at the physiological level, especially the influence of their size and shape on the targeting mechanism, and the key role of material selection in biocompatibility. In view of the urgent need for cancer treatment, this paper analyzes the research route of nanorobots in this field in detail and discusses their application principles as targeted therapy tools. Nanobots provide new solutions for cancer treatment through precise targeting mechanisms and efficient drug loading and release strategies. In addition, this paper highlights innovations in the way nanorobots are driven and manipulated, especially their ability to move in a directional manner in response to external stimuli (e.g., magnetic, light, acoustic, or electric), which significantly improves the precision and efficiency of treatment. However, the application of nanorobots in targeted cancer therapy also faces many risks and challenges, including the limitations of real-time in vivo observation and imaging technology, and the safety of long-term use. These challenges are both a test of existing technologies and a key driver for the further development of nanorobotics. Finally, this paper looks forward to the future development of nanorobots and points out the importance of interdisciplinary cooperation and technological innovation to overcome existing problems and promote the vigorous development of nanomedicine. Nanorobots are expected to play a more important role in cancer treatment and other medical fields and make greater contributions to the cause of human health.
