We have developed a multimodal CMOS sensing device to detect fluorescence image and electrical potential for neural activities in a mouse deep brain. The device consists of CMOS image sensor with on-chip electrodes and excitation light sources, all of which are integrated on a polyimide substrate. The novel feature of this device is its embedded on-chip electrodes which are partially transmit incident...
We have developed CMOS based image sensing devices that can be implanted in a mouse deep brain to monitor the neural activities of a freely-moving mouse. Transgenic mice that express GFP (green fluorescence protein) in the midbrain DA (dopamine) neurons under the control of the rat TH (tyrosine hydroxylase) gene promoter, was used for the experiments. The fluorescence was measured through GFP which...
This paper describes the design, fabrication and characterization of CMOS optical sensors for cancer detection based on autofluorescence emission spectra. These optical sensors were fabricated for being an integrated part of an endoscopic capsule used in diagnosis of gastrointestinal diseases. Cells and tissues show autofluorescence, in a part of the visible spectrum, when excited by ultraviolet or...
We have developed a new method for in vivo functional imaging of the mouse brain using a dedicated CMOS image sensor chip. The image sensor has 176times144-pixels with pixel size of 7.5times7.5 mum 2. A novel packaging process is developed to enable on-chip fluorescence imaging. The sensor chip is attached to a flexible polyimide substrate and sealed in epoxy. A thin-film resist is spin-coated directly...
