Title：Acoustic trapping: an emerging tool in micro-array technologies

Time: 14:00~15:00 PM, Dec 3rd (Tuesday)

Location: Meeting Room #308, Building 910

Abstract：

Spatial indexing is critical in experiments that require to identify and monitor hundreds to millions of individual microcompartments over a range of timescales and chemical/physical environments. This enables the high-throughput analyses of chemical/biochemical, and cellular processes, and the digital measurements of rare events in a large sample. Systematic arrangement of individual or clusters micro-compartments or cells in 2D micro-arrays provides a miniaturized platform, in which the addressability of the objects in the array can be indexed on the basis of one or more spatial variables. Typically, arrays of micro-compartments or cells with a uniform size have been prepared by microfluidics, microfabrication, printing and by application of electrical or magnetic fields. In this talk, I will present some of our recent work on how to utilize ultrasound to organize liquid droplets, lipid vesicles, and cells in 2D micro-array. I will also discuss the use of micro-array for non-equilibrium chemical sensing, protocellular differentiation, the construction of synthetic “prototissues”, exploration of localized enzyme-directed chemical communication, and design of vesicle-mediated chemical communication pathways in protocell/living cell consortia.
