Current techniques to fabricate microneedles remain challenging – sugar-based polymeric materials are unstable at high temperatures in casting methods, other techniques limit drug encapsulation and some require sophisticated machinery, thereby incurring high costs and become inaccessible. In this chapter, we describe a simple photolithographical approach to fabricate polymeric microneedles, using poly (ethylene glycol) diacrylate (PEGDA), a biocompatible and commonly used substrate in tissue engineering. This process is a one-step method by UV photolithography, amenable to other photocrosslinkable polymers and suitable for scaling up commercially.
