From Self-Assembly to Controlled-Assembly, From Optical Manipulation to AFM Manipulation

Moving nanoparticles/atoms to study the nearfield interaction between them is one of the many approaches to explore the optical and electrical properties of these assemblies. Traditional approach included the self assembly by spinning or drying nanoparticles in aqua on the substrate is well practiced. Lithography technique is another popular approach to deposit limited nano/micro patterns on substrates. Later optical and mechanical manipulations were used to have more control over moving individual elements of nano and microstructures and even atoms. Optical tweezers, optical trapping and AFM manipulation are examples of these precise approaches.
