Nanocrystal superlattices

Article Abstract:

An exciting new class of materials is made up of ordered arrays, which may also be called superlattices, of insulating, metallic or semiconducting quantum dots (QDs). Superlattices are often referred to as artificial solids. The nanocrystals in these materials act as atoms do in traditional solids. The packing arrangement of the nanocrystal determines the superstructure unit cell parameters. Various approaches to putting together nanocrystal superlattices are reviewed.

Polymer adsorption-driven self-assembly of nanostructures

Article Abstract:

This review examines the principles underlying functionally useful nanostructure formation by macromolecules such as polymers. Theoretical and computational studies elucidate the principles, as in biomimetic recognition between polymers and patterned surfaces, of nanomechanical motion due to biopolymer adsorption and binding, and creation of nanostructures.

Surface biology of DNA by atomic force microscopy

Article Abstract:

This review describes application of atomic force microscopy techniques to studies focusing on DNA condensation, DNA mapping and sizing, cancer, and nanotechnology. The atomic force microscopy is very useful in studying isolated DNA molecules in terms of their single-molecule-mechanics and thermodynamics.
