Purpose

To create a polycaprolactone mesh which enables cell activity and seeks to eventually provide an application in the field of tissue engineering toward biomimetic skin graft.

Progress since last meeting

Spun 4 more meshes

Visited Janelia Farm and used SEM

Changed procedure slightly

Created Timeline

Electrospun Meshes

All 15 wt. % solution using acetic acid as solvent

15 kV 15cm Used syringe pump (flow rate .02 ml/s)

for first three meshes› Now using pipette to reduce beading
