The invention relates to a method of identifying nuclear receptor controlled genes in specific tissues. The photosensitive unit includes a photosensitive member with a photosensitive layer. If only one of the confidence indices of the two recognition results reaches the threshold, then only this result is used as the output. In further embodiments, the crown comprises a thermally volume-stable material. The radio frequency-responsive element has information storage and transmission capabilities adapted to enable an interrogation system to obtain information from the radio frequency-responsive element.
