Opamps have pretty much always been able to work off of a single supply. even "dual supply" opamps can. The only issue is that they are not optimized for such operation. Particularly in terms of working with very-low supply voltages, inputs near -Vee (0V), and outputs near -Vee (0V).
There are also issues with operating any opamp with a single power supply, especially when a signal extends to DC. This is because to use an opamp with a single supply, a DC bias must be added and possibly removed at a later stage.
a variety of charge pumps exist that can give you a negative rail if one is really justified.
