Experiments on individual molecules using scanning probe microscopies have demonstrated an exciting diversity of physical, chemical, mechanical, and electronic phenomena. They have permitted deeper insight into the quantum electronics of molecular systems and have provided unique information on their conformational and mechanical properties. Concomitant developments in experimentation and theory have allowed a diverse range of molecules to be studied, varying in complexity from simple diatomics to biomolecular systems. At the level of an individual molecule, the interplays of mechanical and electronical behavior and chemical properties manifest themselves in an unusually clear manner. In revealing the crucial role of thermal, stochastic, and quantum-tunneling processes, they suggest that dynamics is inescapable and may play a decisive role in the evolution of nanotechnology.
利用扫描探针显微镜对单个分子进行的实验已经证明了物理、化学、机械和电子现象令人兴奋的多样性。这些实验使人们能够更深入地了解分子系统的量子电子学，并提供了有关其构象和机械性能的独特信息。实验和理论的同步发展使得人们能够研究从简单双原子分子到生物分子系统等各种复杂程度不同的分子。在单个分子层面，机械行为、电子行为和化学性质之间的相互作用以一种异常清晰的方式展现出来。在揭示热、随机和量子隧穿过程的关键作用时，这些实验表明动力学是不可避免的，并且可能在纳米技术的发展中起决定性作用。
