New Optical Array, Multisite Stimulator Advances Optogenetics (IMAGE)
Caption
A) Schematic of the integrated device with the glass Utah Optrode Array (UOA) bonded to a microLED array. Illumination is from the microLED, through the sapphire (which is bonded to the glass UOA) and delivered to tissue either by the glass needles or through interstitial sites. A pinhole layer (not shown) is patterned onto the sapphire substrate of the microLED array before bonding to reduce optical crosstalk. B) Completed device with polymer coated wire bonds permitting independent control of the microLEDs. C) Illumination of a single microLED delivering high-intensity light to the needle tip. D) All 100 sites simultaneously illuminated.
