injection of PVA MBs via microcatheter in microfluid channel

jinjection tests operating the syringe manually, also in reverse flux, to verify the absence of obstructions and damages.Thereafter, the injection syringe was mounted on a programmable, step-by-step motor driven syringe pump system which was set at different constant volumetric flow rates, ranging from 0.05 ml/min to 1.12 ml/min according to material and methods, section "Handling of microcatheters with PVA MBs for insertion in microfluidic channels"
