Photoinhibited superressolution (PInSR) lithography is a two--color, one-photon scheme that promises high throughput far-field patterning t deep subwwabvelength scales. Previous work ha shown that the technique susceptible to blurring from active species diffusion, an issue which we have recently overcome with the use of a low-diffiusivity methrylate resist. Here we present out first clear demonstration of superresolution, showing feature spacing 3X better than the 0.2 NA diffraction limit.
