Outline of Final Research Achievements

Multifunctional polymeric materials with controlled topography and physical/chemical properties were produced by optimizing quantum-beam-induced chemical reactions and their three-dimensional distributions. Particularly, reagent-free functionalization and micro/nanopatterning of biocompatible polymers were realized in this study: gelatin hydrogels having variable stiffness in the range of soft tissue (1-100 kPa) and various micro-topography were developed for controlling cell morphology, and single-step fabrication of polydimethylsiloxane microwell arrays with long-lasting hydrophilic surfaces were fabricated for trapping cells/single-cells.
