Paper based pressure sensor for green electronics [PDF]

2017 IEEE SENSORS, 2017
This work reports a resistive paper-based disposable pressure sensor based on porous 3D conductive cellulose micro-fiber network. The conductivity in microfibers was achieved by subjecting the network to graphene oxide (GO) - poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) solution.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
