ASML offers lithography with a resolution of a couple of nanometres. 
They use very deep ultra-violet irradiation - wavelength 13.5nm - to get 
there.

https://www.asml.com/en/products/euv-lithography-systems

The Nature Photonics paper your puff is based on specifies that their UV
LEDs emit 270nm radiation, twenty times longer, so they aren't in the hunt.

It looks like a useful development, but it isn't going to threaten 
ASML's market.
