Do you have any transimpedance amplifier that can amplify picoampere or lower current ?

  • Any op amp with low low input bias current, can have a resistor added to form a TIA.

    If this is for a photodiode,, see the Wizard:

    Photodiode Circuit Design Wizard | Analog Devices 

    If this is for one system at room temperature, you ccould use almost any CMOS op amp with TYPICAL

    input bias current that is low;  HOWEVER, not a guaranteed max.  E.G.  AD8603.

    If you need guaranteed, see the ADA4530 data sheet, user guide, and app note.  80 pages.
