We develop distributed digital manufacturing of nanomaterials and nanodevices from nanoscale colloidal particles, wires and membranes as building blocks. We invent a series of user-friendly light-powered tools to sculpt and assemble the building blocks into complex architectures in an automated way. Inline metrology enables in-situ structural and functional measurements. 

Many of the basic molecular building blocks of life are chiral species. Chiral molecules are non-superimposable on their mirror images. We develop chiroptical devices that enable high-performance label-free enantiodiscrimination and enantioselective separation of chiral molecules to advance space life detection and to improve studies of the origin and rules of life.

We develop user-friendly light-powered micro/nanorobots and lab-on-a-chip devices to bring healthcare diagnostics and therapy to underserved areas while advancing life sciences. Our robots and devices merge photonics, thermodynamics, fluidics and artificial intelligence at the nanoscale to interrogate tissues, biological cells, organelles and molecules at unprecedented levels.
