The sensor kinase NreB from Staphylococcus carnosus contains an O(2)-sensitive [4Fe-4S](2+) cluster which is converted by O(2) to a [2Fe-2S](2+) cluster, followed by complete degradation and formation of Fe-S-less apo-NreB. NreB.[2Fe-2S](2+) and apoNreB are devoid of kinase activity. NreB contains four Cys residues which ligate the Fe-S clusters. The accessibility of the Cys residues to alkylat...

An increasing integration of nanoscale sensors is being observed in BioSensing and Biomimetic systems. Power consumption is deemed a major limiter as the complexity of integration increases. Supply voltage based scaling using CMOS is also a challenge due to increasing leakage currents. This work presents alternative devices – Interband Tunnel Field Effect Transistors (TFETs) and Split-Gate Quan...
