Latest Patents

One of Xiaoyun Ding's latest patents is titled "Gym on a chip for small animal exercise." This invention introduces a novel on-chip system named Acoustic Gym, designed to control the swimming exercise of small animals, such as zebra fish, at desired intensities and durations. The system utilizes a surface acoustic wave (SAW) device, which consists of a circular chamber filled with fluid, positioned between a pair of offset interdigital transducers (IDTs) on a piezoelectric substrate. When activated by a radio frequency (RF) source, the SAW propagates along the substrate, inducing acoustic streaming in the fluid to stimulate the swimming exercise of small animals. The streaming velocity can be precisely controlled through the RF signal input power, allowing for regulation of the exercise duration and intensity.

Another notable patent is "Cell transfection by precise mechanical membrane disruption." This invention relates to a microfluidic poration device featuring narrow channels slightly smaller than the width of a target cell. The channels are lined with a series of nanospikes that extend down the middle, allowing for simultaneous squeezing of cells while piercing holes in their membranes. This innovative approach enables the introduction of foreign molecules into the cells, with the holes in porated cells spontaneously closing after exiting the channels. The resulting porated cell population boasts approximately 95% viability, with over 50% containing at least one foreign molecule.
