Abstract: The invention generally relates to ion generation using modified wetted porous materials. In certain aspects, the invention generally relates to systems and methods for ion generation using a wetted porous substrate that substantially prevents diffusion of sample into the substrate. In other aspects, the invention generally relate to ion generation using a wetted porous material and a drying agent. In other aspects, the invention generally relates to ion generation using a modified wetted porous substrate in which at least a portion of the porous substrate includes a material that modifies an interaction between a sample and the substrate.
