title = "Notice of Retraction: Si multi-nanochannel FETs to improve device uniformity/stability and detection of 10 fM insulin in serum",
abstract = "Here we demonstrate the use of multiple Si nanochannel (NC) or nanograting (NG) instead of the conventional single channel or nanowire design in biosensors can significantly reduce device to device variation, and improve device performance (higher current, higher ON/OFF ratio, smaller SS, lower Vt) in buffer solution. NG devices also result in higher sensor stability (repeated sensing over tens of hours) in buffer and human serum. We believe such improvements are due to reduced discrete dopant fluctuation and biochemical noise in the solution. The improved devices allow us to sense pH linearly with 3-aminopropyltriethoxysilane (APTES) coated devices, and to selectively detect insulin with limit of detection down to 10fM in both buffer solution and human serum without pre-purification.",
