  1. Biopolymer Solution Background: Using pulsed laser-generated multiphoton excitation to fabricate micron scale hydrogel matrices from biopolymer solutions. Biopolymer Hydrogel Matrix Focused, pulsed laser Microscope Objective Motivation: Use this method to fabricate cell scaffolds for neural tissue engineering applications. Goal:Fabricate hydrogel microstructures with tunable functional and mechanical properties.

  2. Diffusible Gradients Hill & Shear, Analytical Chemistry, 2006

  3. Flat Cubes

  4. Bridges

  5. Stepped Blocks

  6. Next • Functionalization – continue work with diffusible gradients in flow chamber • Modulus – Currently quantifying data from first experiment with Ti:S fabricated structures • CNT – effect of CNT on modulus of GMHA/BSA hybrid structures. • Combined study – Functionalize slabs, note effect on modulus
