Can we use ADA4530-1R-EBZ-TIA for converting pA current from bio sensor to measurable voltage level?

We are building an application where our bio-sensors give us current in the range of 50-200 pA. We need to design a front end that would convert this small current to voltage of appropriate level which can be fed to ADC for digital conversion for processing. We want to use ADA4530-1R-EBZ-TIA board from ADI for our application. Since this is an expensive board for an academic project so we want to be absolutely sure that it is ideal for our application. Please let us know if this board would work. Do you have any instances where this board is used for converting such small currents (pA range) to appropiate voltage levels?
