Summary
A Pico-Newton Scale Force Measurement Apparatus for Polymer Physics and Non-equilibrium Statistical Mechanics. We propose to build a state-of-the-art Optical Tweezers apparatus that measures small forces and torques on micron-sized objects located in 'optical traps'. Using a single laser beam and computer-generated holograms, we will create arrays of optical traps that move or 'dance', and alter the force/torque-imposing properties of each trap. This proposed research equipment will be used (1 ....A Pico-Newton Scale Force Measurement Apparatus for Polymer Physics and Non-equilibrium Statistical Mechanics. We propose to build a state-of-the-art Optical Tweezers apparatus that measures small forces and torques on micron-sized objects located in 'optical traps'. Using a single laser beam and computer-generated holograms, we will create arrays of optical traps that move or 'dance', and alter the force/torque-imposing properties of each trap. This proposed research equipment will be used (1) to study the physics of single synthetic polymer and naturally occuring biopolymer chains, (2) to quantify experimentally, and for the first time, newly predicted molecular-scale forces, and (3) to demonstrate new theories in non-equilibrium statistical mechanics that quantitatively describe the operation of nanomachines.

Self-assembled polyphiles: molecular nanopatterns. 21st century technology is certain to rely on advanced materials, utterly new in character, function and manufacturing process. Control of material structure, from the atomic and molecular scales and upward will be a central focus, to engineer specific features from electronic or photonic functionality, to chemical selectivity.

Control of material structure, from the atomic and molecular scales and upward will be a central focus, to engineer specific features from electronic or photonic functionality, to chemical selectivity. The manufacturing principle of biological materials, made routinely in vivo with exquisite economy and control at all length scales, will be adopted for materials design. The route to these materials is self-assembly. We will explore in detail theory and practical manufacture of self-assembled nanostructured materials, building molecular honeycombs combining composite material features at the nanoscale.Read moreRead less
Single Molecule Studies of Replisomal Function. It has recently become possible to watch the copying of DNA molecules with a specialized microscope in real time. This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work ....Single Molecule Studies of Replisomal Function.

This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work and simultaneously measure the very small forces that the machines generate. This will give Australian scientists access to a new technology for studying molecular machines.Read moreRead less
Salt, Sugar and Sequence: The Effect of Molecular Forces on Polymer Conformation. We propose a combined experimental and theoretical investigation of single polymer chains, exploring how their shape or conformation, and stretching characteristics are affected by specific molecular interactions. Our tools in this study are both experimental and theoretical: optical tweezers, atomic force microscopy, as well as new theories in colloid science, and computer simulation. In particular, we will exa ....Salt, Sugar and Sequence: The Effect of Molecular Forces on Polymer Conformation. We propose a combined experimental and theoretical investigation of single polymer chains, exploring how their shape or conformation, and stretching characteristics are affected by specific molecular interactions. Our tools in this study are both experimental and theoretical: optical tweezers, atomic force microscopy, as well as new theories in colloid science, and computer simulation. In particular, we will examine the effect of different salts and sugars upon the properties of polymers such as DNA, and how monomer sequence can lead to dramatically different structures in solution which in turn will lead to novel materials.Read moreRead less

This application seeks to exploit our established lead in the measurement of diffuse scattering from disordered materials and its analysis using large-scale computer simulations. Many industrially important materials such as ceramics, superconductors, catalysts, electro-optical materials and minerals owe their special properties to the disorder in their structure. This disorder causes diffuse X-ray scattering which can be probed using synchrotron X-rays and powerful computers to reveal details about the material's nanoscale structure. The new methodology being developed will enhance our detailed understanding of the relationships between structure and properties in materials and help promote the design of new materials.

Polymer Globules: Beyond the Homopolymer Model. Polymers are long chainlike molecules which play a crucial role in many aspects of our lives. As plastics they represent the most versatile and ubiquitous of man-made materials. Moreover, all living things depend on polymers for the structure of their cells and for the inheritance and function through DNA and proteins. Despite their importance our understanding of polymers is rather limited. The research funded by this proposal will enable us to ....Polymer Globules: Beyond the Homopolymer Model.

Moreover, all living things depend on polymers for the structure of their cells and for the inheritance and function through DNA and proteins. Despite their importance our understanding of polymers is rather limited. The research funded by this proposal will enable us to understand more complicated kinds of polymers. This will help uncover some fascinating physics and in the long term develop new materials and promote new advances in biology. Read moreRead less
Macromolecular Condensates: From Globules to Toroids and Beyond. Polymers are long-chain molecules which are vital for all living things. Examples include proteins and DNA which carries all of the information needed for life. In the cell and in the laboratory these polymers are often found in a compact folded state. Current polymer science is good at describing very flexible polymers, but fails to describe most biological polymers which have backbones that are difficult to bend.

It is responsible for the growth of complex multiscale structures found in biology and materials science and is a crucial concept for development of viable nanotechnologies. Complex systems, from biological ecosystems to financial markets and the Internet, are also characterized by spontaneous clustering and linkages that determine their collective behaviour.
