This comprehensive review provides contemporary knowledge on the design approaches of dissolvable transdermal microneedles, the materials science facilitating these delivery systems, and the opportunities these advanced materials can provide to enhance clinical outcomes.
Dissolvable transdermal microneedles (mu ND) are promising micro-devices used to transport a wide selection of active compounds into the skin. To provide an effective therapeutic outcome, mu NDs must pierce the human stratum corneum (~10 to 20 mu m), without rupturing or bending during penetration, then release their cargo at the predetermined area and time. The ability of dissolvable mu ND arrays/patches to sufficiently pierce the skin is a crucial requirement, which depends on the material composition, mu ND geometry and fabrication techniques. This comprehensive review not only provides contemporary knowledge on the mu ND design approaches, but also the materials science facilitating these delivery systems and the opportunities these advanced materials can provide to enhance clinical outcomes.
