Drug Needle injectors have been the common means by which vaccines and protein therapeutics are transdermally delivered. However, the use of needle injectors have elicited painful reactions, and have also caused infection due to repeated use of needles particularly in under-developed countries . Because of these disadvantages, researchers have endeavored to developing alternative methods for drug delivery. New methods incorporating liquid jet injections have been developed ; however, liquid jet has not succeeded in replacing needle based injectors yet. Despite the fact that jet injection can alleviate patients aversion to needles, it has not gained much popularity for the following reasons: i) it is still reported to be painful, ii) it is not stabilized in control, and iii) the risk of cross-contamination due to back splash is still prevalent [3, 4]. Therefore, in order to release the stronghold that needle injection has on the drug delivery domain, methods such as jet injection must make a major breakthrough.
