Abstract
Nowadays, microneedles are attracting a lot of attention because microneedles can deliver drugs, vaccines and hormones into the body without pain unlike conventional hypodermic needles. Furthermore, microneedles are safe for self-injection and disposal. This work aims to develop novel microneedles made of a solution of polystyrene (PS) in toluene. The mechanical properties of the fabricated PS microneedles were characterized in failure strength test and skin penetration test. According to the experimental results, a PS microneedle could withstand a large force up to 1.0 N without fracturing. Owing to the superior mechanical strength, the PS microneedles could penetrate the skin without any deterioration making them a promising alternative for commercial applications.
