Hi, I'm currently working on an undergraduate project concerning the optical fabrication of nanoparticles and have come across a problem.
One of the methods that we're charged with investigating is photo induced polymerisation. The wavelengths of light used to induce these reactions is typically in the UV range. If I was to induce the reaction using a beam with a wavelength 300nm, would the smallest feature size I'd be able to create also be limited at 300nm, or is there a way of creating smaller features perhaps using two photon absorption or other methods?
Any input, help, ideas or suggestions would be welcome, thanks.
