Dehydration was completed by covering the scaffolds in hMDs ( hexamethyldisilazane) ( Sigma ) for minutes and repeating.

Scaffolds were left overnight in a fume-hood for any remaining HMDS to evaporate fully. Micro-pipettes were pulled on a horizontal micro-electrode puller (PN Narishige, Tokyo) with tip apertures below um and silanized with hexamethyldisilazane ( HMDS , Sigma , St. Louis) at the comparatively low temperature of 120°C. Protocol A: Preparation of photoresist-coated glass coverslips 1. Wash with toluene ultrasonic bath 15min.

The cell- scaffold constructs were then attached to aluminum stubs, sputter-coated with gol and then examined under a LEO-Gemini Schottky FEG scanning electron microscope. HMDS has the desirable property of reacting more selectively, in some instances, than other reagents. SIGMA -ALDRICH sigma -aldrich. It is a popular choice for silylating .
