This cutting-edge book moves from the current ability to position nanoparticles on surfaces, to a new dimension of spatial control. The authors report that a new technique called “nanoscopic lens” is able to produce a variety of 3D nano-structures in a controlled manner. Particle trajectory calculations can efficiently predict the whole process of 3D assembly. The nanoscopic lens technique serves as the foundation of a multifaceted technology for device development including creating a wide range of bio-nanoelectronic devices.
