Silk patterns made by direct femtosecond laser writing
journal contribution
posted on 2016-09-01, 00:00 authored by K Maximova, X Wang, A Balčytis, Linpeng Fan, Jingliang LiJingliang Li, S JuodkazisSilk patterns in a film of amorphous water-soluble fibroin are created by tailored exposure to femtosecond-laser pulses (1030 nm/230 fs) without the use of photoinitiators. This shows that amorphous silk can be used as a negative tone photoresist. It is also shown that water insoluble crystalline silk films can be precisely ablated from a glass substrate achieving the patterns of crystalline silk gratings on a glass substrate. Bio-compatible/degradable silk can be laser structured to achieve conformational transformations as demonstrated by infrared spectroscopy.
