The Architecture of Nanorobots: From Advanced Materials to Structural Visualization

Nanorobots represent a significant technological frontier with applications ranging from targeted drug delivery to environmental remediation. Their successful engineering depends on the synergy between advanced materials-including inorganic, organic, and framework structures-and the sophisticated design logic that governs their function at the nanoscale. This review places a special emphasis on the pivotal role of advanced structural characterization in bridging design with application. We highlight how microscopy techniques, such as Transmission Electron Microscopy and Scanning Probe Microscopy, provide essential high-resolution feedback on atomic structures and dynamic behaviors. This characterization-driven approach is critical for validating design concepts, optimizing performance, and ultimately enhancing the functionality and reliability of next-generation nanorobots.
