LPL40: Digitized Microfluidic Device for Single Cell Analysis


Most of current clinical diagnosis is based on observation and analysis on a large number of cells, which provides averaged or integrated information about the disease state. However, many diseases start from a small number of mutated or unhealthy cells while most other cells remain normal. In order to detect these precursors as early as possible, a high throughput single cell based detection method is required for the analysis of large number of cells from tissue samples. Here we report a microfluidic device where individual cells are encapsulated in nano-liter aqueous compartments separated by non-aqueous (oil) compartments in a fast flowing micro-channel. Subsequent single cell lysis and analysis, including DNA amplification and biochemical assay, can be applied to each cell compartment on the same chip without contamination from other compartments.
