(1) Physical modification of biomaterials
(2) Chemical modification of biomaterials

24 hr study illustrating cell viability using live/dead assay (green-live, red-dead)
72 hr study illustrating cell viability using live/dead assay (green-live, red-dead
Cells: PC12 (rat adrenal tumor cells) neuron-like cells used in study
Material: Copolymer of poly-lactic acid (PLA) and poly-ethylene glycol (PEG)
*Control: Cells were plated on the same surface area using plexiglass wells on polystyrene TC dishes
Conclusion: Results showed excellent potential for NGC development
using Microfab polymer, because in vitro studies demonstrated
comparable PC12 adhesion and viability

Biotin moieties presented at the polymer surface are used to immobilize tetrameric avidin molecules. Free biotin binding sites on the avidin molecules are in turn used to anchor biotinylated ligands such as, bNGF.
