1.3 Mega pixels CCD pH imaging sensor with 3.75 μm spatial resolution

We have demonstrated for the first time a megapixel (1.3M pixels) CCD pH imager featuring a flash-injection-of-signal-electrons scheme. With a spatial resolution of 3.75μm and pH resolution of 0.16pH at 27.5fps we believe this is a promising device technology for applications such as high throughput DNA sequencing and label-free cell measurement system with sub-cell-size spatial resolution and real-time response.
