Available in PDF, EPUB and Kindle. Book excerpt: At the nanometer scale, the physical and chemical properties of materials heavily depend on their sizes and shapes. This fact has triggered considerable efforts in developing controllable nanomaterial synthesis. The controlled growth of colloidal nanocrystal is a kinetic process, in which high-energy facets grow faster and then vanish, leading to a nanocrystal enclosed by low-energy facets. Identifying a surfactant that can selectively bind to a particular crystal facet and thus lower its surface energy, is critical and challenging in shape controlled synthesis of nanocrystals. Biomolecules exhibiting exquisite molecular recognition properties can be exploited to precisely engineer nanostructured materials. In the first part of my thesis, we employed the phage display technique to select a specific multifunctional peptide sequence which can bind on Pd surface and mediate Pd crystal nucleation and growth, achieving size controlled synthesis of Pd nanocrystals in aqueous solution. We further demonstrated a rational biomimetic approach to the predictable synthesis of nanocrystals enclosed by a particular facet in the case of Pt. Specifically, Pt {100} and Pt {111} facet-specific peptides were identified and used to synthesize Pt nanocubes and Pt nano-tetrahedrons, respectively. The mechanistic studies of Pt {111} facet-specific peptide had led us to study the facet-selective adsorption of aromatic molecules on noble metal surfaces. The discoveries had achieved the development of design strategies to select facet-selective molecules which can synthesize nanocrystals with expected shapes in both Pt and Pd system. At last, we exploited Pt facet-specific peptides and controlled the molecular interaction to produce one- and three- dimensional nanostructures composed of anisotropic nanoparticles in synthetic conditions without supramolecular pre-organization, demonstrating the full potential of biomolecules in mediating material formation process. My research on biomimetic synthesis of nanocrystals with shape control and nanostructures with control over the anisotropy are unprecedented, representing a step forward in achieving the goal of producing complex nanostructures with required properties. The fundamental studies on the biomolecule-inorganic interfaces have contributed to advancing the synthesis tool of colloidal nanomaterials and enriching understating of organic-inorganic interface, impacting many applications.

Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor nanocrystals are used widely as biological labels and components of optoelectronic devices. The spectral tunability and stability of these materials makes them ideal building blocks and probes. This thesis describes work on a class of semiconductor nanocrystals with properties controlled by the structure and sequence of nucleic acids. Controlling nanocrystal properties using rationally designed nucleic acids structures and sequences presents a new means to engineer inorganic structures with desired properties, and provides a means to produce biofunctionalized imaging labels in a single step. The materials produced using this approach have favorable characteristics, including bright emission, high stability, and straightforward synthetic manipulation.The properties of semiconductor nanocrystals are known to be strongly dependent on the ligand used during synthesis that serves to passivate the surface. We endeavored to use a class of ligands that would have intrinsic self-assembly properties and inherent biocompatibility. We therefore tested nucleic acids including DNA and RNA molecules as ligands for cadmium and lead-based nanocrystals formation. Nucleic acids molecules passivate on semiconductor nanocrystal surface through their nucleobase functionalities as well as the phosphate backbone. Among the four natural mononucleotides, guanine is the most effective nucleotide for semiconductor nanocrystals formation. Semiconductor nanocrystals synthesized with different DNA homopolymer sequences possess distinct luminescence intensities. A general approach is being developed to systematically control semiconductor nanocrystals luminescence using rationally designed DNA sequences. In addition, the effect of nucleic acids structure on CdS semiconductor nanocrystals properties is elucidated using transfer RNA molecules as a ligand system, and differences in size and morphology were observed for the semiconductor nanocrystals synthesized with different RNA structures.DNA-passivated semiconductor nanocrystals exhibit low cytotoxicity and high stability in biological media and thus are superior for bioimaging applications. Given the molecular recognition properties of DNA and RNA aptamers with other biomolecules such as proteins or cell surface receptors, we were inspired to use a bi-functional DNA template to generate biofunctionalized semiconductor nanocrystals in a simple one-pot process. This novel strategy is realized by the design of a chimeric DNA template with a phosphorothioate domain for semiconductor nanocrystals passivation and a phosphate domain (aptamer) for biomolecule recognition. CdTe semiconductor nanocrystals synthesized with the chimeric DNA template possess high specificities towards the cognate DNA, protein, and cancer cell targets.
