Controlled propulsion of artificial magnetic nanostructured propellers.
For biomedical applications, such as targeted drug delivery and microsurgery, it is essential to develop a system of swimmers that can be propelled wirelessly in fluidic environments with good… Expand
Swimming by reciprocal motion at low Reynolds number
Biological microorganisms swim with flagella and cilia that execute nonreciprocal motions for low Reynolds number (Re) propulsion in viscous fluids. This symmetry requirement is a consequence of… Expand
Direct chiral discrimination in NMR spectroscopy
Abstract Conventional nuclear magnetic resonance spectroscopy is unable to distinguish between the two mirror-image forms (enantiomers) of a chiral molecule. This is because the NMR spectrum is… Expand
Hybrid nanocolloids with programmed three-dimensional shape and material composition.
Tuning the optical, electromagnetic and mechanical properties of a material requires simultaneous control over its composition and shape. This is particularly challenging for complex structures at… Expand
Nanopropellers and their actuation in complex viscoelastic media.
Tissue and biological fluids are complex viscoelastic media with a nanoporous macromolecular structure. Here, we demonstrate that helical nanopropellers can be controllably steered through such a… Expand
Holograms for acoustics
We introduce monolithic acoustic holograms, which can reconstruct diffraction-limited acoustic pressure fields and thus arbitrary ultrasound beams. Expand

We developed a method of constructing 3D organ models from medical imaging data using a 3D wax printing and molding process to make a human kidney phantom with realistic anatomical structures and physical properties. Expand
Diffusion Measurements of Swimming Enzymes with Fluorescence Correlation Spectroscopy.
Self-propelled chemical motors are chemically powered micro- or nanosized swimmers. The energy required for these motors' active motion derives from catalytic chemical reactions and the… Expand

Motility in living systems is due to an array of complex molecular nanomotors that are essential for the function and survival of cells. These protein nanomotors operate not only despite of but also… Expand
