In our recent study, which was published in Nanotechnology, low dose FIB processing was performed on extremely soft polymeric material (PDMS) by flooding an electron beam simultaneously on the fabricated area to relieve charge accumulation.

The proposed approach for the fabrication of ordered nanostructure arrays using a FIB could provide a promising way of constructing various functional structures or devices on electrically insulating surfaces such as biotemplates, microlenses, multifunctional microfluidic devices and waveguides with diffractive optical structures.

Systematic studies focusing on protein nanopatterning and high-throughput bioassays are underway in the group's lab based on the well defined nanodot and nanohole arrays.
