As the innovation of the digitized world, the chip continues to shrink the pitch with increased transistor density, increased speed and reduced power consumption. I developed various novel methods which can achieve high precision patterns and manufacturing of functional metamaterials or atomic nanodevices. With the capability of achieving high-throughput, versatile, and maskless patterning on different materials, my technique can be used to significantly improve the throughput and precision for the development of microelectronic devices, including field-effect transistors, photon detectors, light emitting diodes, and solar cells.

I focused on developing new tools to improve the optical manipulation with high precision. For instance, I developed versatile optical techniques using optical heating to manipulate microscopic objects. The novelty of these works relies on laser-driven heating to achieve trapping, which shows significant improvement over the conventional optical tweezer. My technique has more applicability thanthe conventional technique and manipulations of the nanoobjects (i.e., metallic particles and vesicles), which can hardly be achieved using conventional techniques, have been demonstrated.

I aimed to solve a problem that has been troubling the biological and pharmaceutical industry for decades, which is the lack of a way for rapid chirality sensing of chiral molecules and their precursors at low sample consumption. My solution to this problem is a lap-on-a-chip chiral sensor device with strong chiral plasmonic resonances. Benefiting from its ultra-high sensitivity and compactness, our lab-on-a-chip chiroptical nano-device significantly facilitates the enantiodiscriminative characterization of drug-related molecules, thus reducing the cost and increasing the efficiency during drug development processes.
