Abstract
A microneedle assembly that is capable of delivering a drug compound (e.g., vaccine) and/or detecting the presence of an analyte is provided. The assembly comprises at least one microneedle extending outwardly from a support. The microneedle includes a polymer composition containing a thermoplastic polymer having a melting temperature of about 250° C. or more. The polymer composition exhibits a melt viscosity of about 100 Pa-s or less and a tensile elongation of about 5% or less.
Claims52
A microneedle assembly comprising at least one microneedle extending outwardly from a support, wherein the microneedle includes a polymer composition containing a thermoplastic polymer having a melting temperature of about 250° C. or more, wherein the polymer composition exhibits a melt viscosity of about 100 Pa-s or less as determined in accordance with ISO Test No. 11443:2014 at a shear rate at a shear rate of 1,000 seconds−1 and temperature of about 30° C. above the melting temperature, and further wherein the polymer composition exhibits a tensile elongation of about 5% or less as determined at in accordance with ISO Test No. 527:2012 at a temperature of about 23° C.
