研制了一种用于pH和光学成像的低干扰多模态传感器。pH值和光学输出之间发生的干扰信号被发现是由光生电子在pH传感过程中引起的。这种干扰可以通过向传统的多模态传感器结构添加另一个电荷积累区域来抑制，以便仅测量光生电子。常规pH感测装置结合用于光生电子的联合收割机积累区域，从而区分pH和光学信号。
A low-interference multimodal sensor for pH and optical imaging has been developed. The interference signal that occurs between pH and the optical outputs is found to be caused by photogenerated electrons during pH sensing. This interference could be suppressed by adding another charge-accumulation region to a conventional multimodal sensor structure in order to measure only photogenerated electrons. Conventional pH sensing devices combine accumulation regions for photo generated electrons, thereby discriminating between pH and optical signals.
