we guess, we had uncompleted reaction between formalin and phenol or some changes are needed in process.
and also we need to have final resin with 50% solid content and 200 cp in viscosity.
The endothelial cells have more affinity to positively surface of polymer scaffold, I want to know why ECs were attached to that nanoparticles which I called. Please help me.
