IEEE Trans Nanobioscience 2:138-45. 2003..76 microm. In addition, L929 might grow only on the top of the laser-patterns attaching the ridges when the groove widths were narrow, but might grow into the microgrooves when the width went beyond 5.04 microm...
- Laser interference lithography as a new and efficient technique for micropatterning of biopolymer surfaceFayou Yu
Department of Materials Science, Saarland University, D 66123 Saarbrucken, Germany
Biomaterials 26:2307-12. 2005..The AFM photographs show that the micropatterns are well-defined and of great consistency. Polymer properties and laser parameters related to LIL as well as laser ablation mechanisms are discussed in this technical note...
