Patent ID: 8480945

Claim:
An electrospinning manufacture for drug carriers, comprising: a preliminary step mixing an alginate with a predetermined drug in a ratio of 2:1 and then dissolving the mixed predetermined drug and alginate in a saline to obtain a mixture wherein a combined weight of the predetermined drug and the alginate is 0.5 to 3 wt % in the saline; an electric field establishing step providing a collection plate and an emitter, filled with divalent cation agent and the mixture, respectively, wherein a voltage is applied to the collection plate and the emitter to form an electric field from 45 to 150 KV/m therebetween; and an electrospinning step sequentially dropping the mixture from the emitter into the divalent cation agent filled in the collection plate with a speed of 0.5 to 3 milliliter per hour via the driving of the electric field, triggering a crosslinking-gelating reaction between the divalent cation and the alginate to form a gel coating serving as a drug carrier.
