| 20100075867 | Rotating Microfluidic Array Chips - A microfluidic chip for carrying out live cell assays and showing observable color change is provided. The microfluidic chip has at least one fluid channel and a plurality of holes punched in a first side of the chip in fluid communication with the at least one fluid channel. Gelled medium containing live cells may be applied to the holes without obstructing the at least one fluid channel. A plain disk is applied to a second side of the chip to seal the fluid channels. Liquid to be distributed to the cells in the holes may be flowed through the at least one fluid channel by spinning the chip. The gelled medium may alternatively contain a reagent to be assayed by producing an observable change upon interaction with a second reagent when the chip is spun. | 03-25-2010 |
