Atomic force microscopy (AFM) has become an important tool to characterize and image surfaces with nanoscale resolution. AFM imaging technique has been utilized to study a wide range of substances such as DNA, proteins, cells, silicon surfaces, nanowires etc. Hence AFM has become extremely important in the field of biochemistry, cell biology and material science. Functionalizing the AFM tip made it possible to detect molecules and their interaction using recognition imaging at single molecule level. Also the unbinding force of two molecules can be investigated based on AFM based single molecule force spectroscopy. In the first study, a new chemical …

Deoxyribonucleic acid (DNA) has emerged as an excellent molecular building block for nanoconstruction in addition to its biological role of preserving genetic information. Its unique features such as predictable conformation and programmable intra- and inter-molecular Watson-Crick base pairing interactions make it a remarkable engineering material. A variety of convenient design rules and reliable assembly methods have been developed to engineer DNA nanostructures. The ability to create designer DNA architectures with accurate spatial control has allowed researchers to explore novel applications in directed material assembly, structural biology, biocatalysis, DNA computing, nano-robotics, disease diagnosis, and drug delivery. This dissertation focuses on developing …
