A microneedle assembly that is capable of transdermal delivery of a drug compound, such as a vaccine, (e.g., vaccine) across a dermal barrier of a subject (e.g., human), and/or detecting the presence of an analyte in the subject is provided. The microneedle assembly comprises a plurality of microneedles arranged on a support that each contain a tip and base, one or both of which are formed from a polymer composition that includes a liquid crystalline polymer. By selectively controlling the specific components of the polymer composition, as well as their relative concentration, the resulting microneedles may exhibit a high degree of physical alignment, which can help ensure better performance during use of the microneedle assembly.
A microneedle assembly comprising an array of microneedles being arranged in at least one predetermined geometric pattern on a support, wherein the microneedles contain a base that includes a lower portion positioned in proximity to the support and an opposing upper portion extending from the lower portion in a longitudinal direction, wherein a tip extends from the upper portion of the base in the longitudinal direction and terminates at an edge, the tip, the base, or a combination thereof include a polymer composition containing a liquid crystalline polymer, and wherein a centerline extends through the base in the longitudinal direction, and further wherein the microneedles exhibit an offset factor, k, of about 20 or less as determined according to the following equation:
